## Key Improvements
| Aspect | Before (Pushgateway) | After (gitops-status-server) |
|--------|---------------------|-------------------------------|
| **Data Format** | Single metric (0/1) | Rich JSON with metadata |
| **File Details** | None | List of changed files |
| **Infrastructure** | Prometheus + Pushgateway | Single service call |
| **Query Language** | PromQL | Simple JSON API |
| **Grafana Plugin** | Prometheus DS | Infinity DS (native) |
| **Audit Trail** | Basic | Structured snapshots |
| **Setup Complexity** | High | Low |
| **Multi-repo Support** | Difficult | Built-in |
---
## Testing Scenarios
### Scenario 1: Server is synced
```
Cron triggers → drift-check runs → No changes found
→ SYNC_STATUS=SYNCED → JSON sent → Grafana shows ✓ SYNCED (0 drift)
```
### Scenario 2: Manual file edit
```
Someone edits /etc/rsyslog.conf directly on server
→ Cron triggers (≤2 min) → drift-check detects change
→ DRIFTED_FILES=/etc/rsyslog.conf → JSON sent
→ Grafana shows ✗ OUT_OF_SYNC (1 drift: rsyslog.conf)
```
### Scenario 3: Deploy succeeds
```
Push to master → Pipeline runs → deploy completes
→ update-gitops-status runs → drift-check shows no drift
→ JSON sent: SYNC_STATUS=SYNCED → Grafana updated
```
### Scenario 4: Manual drift recovery
```
Admin runs ansible apply to fix drift
→ Next cron (≤2 min) → drift-check shows SYNCED
→ JSON sent: SYNC_STATUS=SYNCED
→ Grafana updates to show ✓ SYNCED (0 drift)
```

# Debugging GitOps Status Issues
This guide helps troubleshoot issues with the GitOps status reporting system.
## Common Issue: Status shows OUT_OF_SYNC after deployment
### Symptoms
- You pushed changes to the repo
- The deploy step succeeded
- But `update-gitops-status` shows OUT_OF_SYNC
- Changed files are not displayed
### Root Causes
#### 1. **Deployment didn't actually succeed**
The deploy step might have failed silently or the configuration wasn't applied correctly.
**How to check:**
- Look at the deploy step logs in Woodpecker
- SSH to the server and verify files match Git:
```bash
diff /etc/rsyslog.conf files/rsyslog.conf
diff -r /etc/rsyslog.d/ files/rsyslog.d/
```
#### 2. **Parsing issue with DRIFTED_FILES output**
The script might not be correctly extracting the file list from Ansible's output.
**How to debug:**
Run the status update script locally with debug mode:
```bash
export KEEP_PLAYBOOK_LOG=true
./update-gitops-status.sh
```
This will save the playbook output to `drift-check-output.log`. Check:
- Does the log contain `DRIFTED_FILES=` line?
- What does the line look like exactly?
- Are there ANSI color codes interfering?
Look for these debug lines in the output:
```
DEBUG: Searching for DRIFTED_FILES in playbook output...
DEBUG: Found DRIFTED_FILES pattern
DEBUG: Raw line: ...
DEBUG: Extracted value: '...'
```
#### 3. **Too many open files error**
If you see "failed to create fsnotify watcher: too many open files":
**Fixed in latest version:**
- `.woodpecker.yml` now sets `ANSIBLE_CALLBACKS_ENABLED=""` and `ANSIBLE_GATHERING=explicit`
- `update-gitops-status.sh` uses `ANSIBLE_CALLBACKS_ENABLED=""` when running playbooks
- These settings prevent Ansible from exhausting inotify watches
**If issue persists:**
- The container might need privileged mode to adjust kernel parameters
- Or reduce Ansible parallelism in inventory settings
#### 4. **Ansible output format changed**
If Ansible version changed, the debug output format might be different.
**How to fix:**
Check `drift-check-output.log` and adjust the parsing in `update-gitops-status.sh`:
```bash
# Current parsing (line ~110 in update-gitops-status.sh):
DRIFTED_FILES_STR=$(echo "$DRIFTED_FILES_STR" | sed 's/.*DRIFTED_FILES=//' | sed 's/\x1b\[[0-9;]*m//g' | sed 's/".*$//' | xargs)
```
You might need to adjust the `sed` commands based on the actual format.
## Testing the Fix
### 1. Test locally
```bash
# Set up SSH key
export SSH_PRIVATE_KEY="$(cat ~/.ssh/id_rsa)"
# Run the script with debug output
export KEEP_PLAYBOOK_LOG=true
./update-gitops-status.sh
# Check the log
cat drift-check-output.log | grep -A 2 "DRIFTED_FILES="
```
### 2. Test in Woodpecker
Push a small change and monitor the `update-gitops-status` step:
```bash
# Make a small comment change
echo "# Test change $(date)" >> files/rsyslog.conf
# Commit and push
git add files/rsyslog.conf
git commit -m "test: verify gitops status detection"
git push
# Watch the pipeline in Woodpecker UI
# The update-gitops-status step should:
# 1. Run deploy (apply.yml)
# 2. Run drift-check immediately after
# 3. Show SYNCED (because deploy just ran)
# 4. Show no drifted files
```
### 3. Test drift detection (manual change on server)
```bash
# SSH to the server
ssh rsyslog-lab
# Make a manual change
echo "# Manual change" >> /etc/rsyslog.conf
# Wait for the cron job to run (every 2 minutes)
# Or manually trigger it in Woodpecker
# The status should now show:
# - Status: OUT_OF_SYNC
# - Files: rsyslog.conf
```
## Expected Behavior
### After successful deployment (push to master)
```
Step 2/4: Analyzing drift detection results...
✓ Status: SYNCED - server configuration matches Git
Total drift count: 0
Step 3/4: Building JSON payload...
Generated JSON:
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-22T14:30:00Z"
}
```
### When drift is detected (cron job or manual server change)
```
Step 2/4: Analyzing drift detection results...
✗ Status: OUT OF SYNC - configuration drift detected
- Drift detected in: rsyslog.conf
Total drift count: 1
Step 3/4: Building JSON payload...
Generated JSON:
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 1,
"files": [
{"name": "rsyslog.conf"}
],
"last_check": "2026-04-22T14:32:00Z"
}
```
## Quick Reference
### Enable debug mode
```bash
export KEEP_PLAYBOOK_LOG=true
./update-gitops-status.sh
cat drift-check-output.log
```
### Manually run drift-check
```bash
ansible-playbook -i ansible/inventory/hosts.yml ansible/playbooks/drift-check.yml
```
### Manually run deployment
```bash
ansible-playbook -i ansible/inventory/hosts.yml ansible/playbooks/apply.yml
```
### Check server state
```bash
ssh rsyslog-lab "md5sum /etc/rsyslog.conf /etc/rsyslog.d/*.conf"
md5sum files/rsyslog.conf files/rsyslog.d/*.conf
```

## Implementation Details
### Workflow Stages
**Stage 1: Cron Detection (Every 2 minutes)**
```
Cron timer triggers
→ update-gitops-status.sh runs
→ drift-check.yml compares files
→ Changed files extracted
→ JSON generated
→ POST to gitops-status-server
→ Grafana reads /status.json
→ Dashboard updated
```
**Stage 2: Post-Deployment (Immediate after push)**
```
Push to master
→ Pipeline: syntax-check → validate → deploy → update-gitops-status
→ Deployment completes
→ Drift check verifies sync
→ JSON sent to gitops-status-server
→ Grafana updates immediately
```
### JSON Payload Structure
**Template (Synced):**
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
**Template (Out of Sync):**
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:30:00Z"
}
```

# Deployment Checklist
This checklist guides you through deploying the updated rsyslog repository with gitops-status-server integration.
## Prerequisites
Before deploying, ensure:
- [ ] gitops-status-server is deployed and accessible at:
`http://gitops-status-server.observability-stack.svc.cluster.local:80`
- [ ] gitops-status-server has `/api/status` endpoint implemented (see [GITOPS_STATUS_API_REFERENCE.md](GITOPS_STATUS_API_REFERENCE.md))
- [ ] Woodpecker CI is configured for this repository
- [ ] SSH access to rsyslog-lab server is configured
- [ ] SSH_PRIVATE_KEY secret is set in Woodpecker repository settings
## Files Changed/Added
### New Files
- ✅ `update-gitops-status.sh` - Main script for JSON status generation
- ✅ `GITOPS_STATUS_INTEGRATION.md` - Integration documentation
- ✅ `GITOPS_STATUS_API_REFERENCE.md` - API reference with examples
- ✅ `MIGRATION_SUMMARY.md` - Summary of all changes made
### Modified Files
- ✅ `.woodpecker.yml` - Updated pipeline to use JSON status
- ✅ `README.md` - Updated documentation with new flow
### Unchanged Files (no action needed)
- ✅ All Ansible playbooks
- ✅ All Ansible inventory files
- ✅ All rsyslog config files
- ✅ Local scripts (apply.sh, drift-check.sh)
## Deployment Steps
### 1. Review Changes
- [ ] Read [MIGRATION_SUMMARY.md](MIGRATION_SUMMARY.md) to understand all changes
- [ ] Review [.woodpecker.yml](.woodpecker.yml) pipeline changes
- [ ] Review [update-gitops-status.sh](update-gitops-status.sh) script logic
### 2. Verify gitops-status-server
Test the gitops-status-server API endpoint:
```bash
# Test POST endpoint (should return 200 or 404 if not implemented yet)
curl -X POST http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status \
-H "Content-Type: application/json" \
-d '{
"repo": "test",
"server": "test",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:00:00Z"
}'
# Test GET endpoint
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json
```
If the API is not implemented yet:
- [ ] Implement gitops-status-server API (use [GITOPS_STATUS_API_REFERENCE.md](GITOPS_STATUS_API_REFERENCE.md))
- [ ] Deploy to Kubernetes cluster
- [ ] Verify endpoints are accessible
### 3. Test Locally (Optional)
Before pushing to Git, you can test the script locally:
```bash
# Set environment variables
export GITOPS_STATUS_SERVER_URL="http://gitops-status-server.observability-stack.svc.cluster.local:80"
export REPO_NAME="rsyslog"
export SERVER_NAME="rsyslog-lab"
# Make script executable
chmod +x update-gitops-status.sh
# Run the script (requires Ansible, jq, curl)
./update-gitops-status.sh
```
Expected output:
```
==> Running drift check playbook...
Inventory: ansible/inventory/hosts.yml
Playbook: ansible/playbooks/drift-check.yml
==> Status: SYNCED - server configuration matches Git
==> Drift count: 0
==> Generated JSON status:
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
==> Sending status to gitops-status-server...
URL: http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status
==> Status update successful (HTTP 200)
```
### 4. Commit and Push Changes
```bash
# Stage all changes
git add .
# Commit
git commit -m "Migrate from Pushgateway to gitops-status-server JSON status
- Add update-gitops-status.sh script for JSON status generation
- Update .woodpecker.yml to use gitops-status-server
- Remove Pushgateway metric push logic
- Add comprehensive documentation
- Keep all Ansible playbooks unchanged"
# Push to master (will trigger deploy pipeline)
git push origin master
```
### 5. Monitor First Deployment
After pushing to master:
- [ ] Watch Woodpecker pipeline execution
- [ ] Verify `syntax-check` step passes
- [ ] Verify `validate` step passes
- [ ] Verify `deploy` step completes
- [ ] Verify `update-gitops-status` step runs successfully
- [ ] Check that JSON is sent to gitops-status-server
Example successful `update-gitops-status` step output:
```
==> Running post-deploy GitOps status check...
==> Running drift check playbook...
==> Status: SYNCED - server configuration matches Git
==> Drift count: 0
==> Generated JSON status: {...}
==> Sending status to gitops-status-server...
==> Status update successful (HTTP 200)
==> JSON status update complete. Pipeline always succeeds.
```
### 6. Verify Cron Pipeline
The cron pipeline runs every 2 minutes:
- [ ] Wait for next cron execution
- [ ] Check Woodpecker for `gitops_sync_check` pipeline run
- [ ] Verify JSON status is sent
- [ ] Verify pipeline succeeds (if synced) or fails (if drift detected)
### 7. Test Drift Detection
Manually create drift to test detection:
```bash
# SSH to the server
ssh rsyslog-lab
# Edit a config file
echo "# manual edit" >> /etc/rsyslog.conf
# Wait up to 2 minutes for next cron run
```
Expected behavior:
- [ ] Cron pipeline runs
- [ ] Drift detected in Ansible playbook
- [ ] JSON sent with `sync_status: "OUT_OF_SYNC"`
- [ ] JSON includes `files: [{"name": "rsyslog.conf"}]`
- [ ] Pipeline marked as FAILED (for visibility)
Verify in gitops-status-server:
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json
```
Should show:
```json
[
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 1,
"files": [
{"name": "rsyslog.conf"}
],
"last_check": "...",
"updated_at": "..."
}
]
```
### 8. Configure Grafana Dashboard
- [ ] Add Infinity datasource pointing to gitops-status-server
- [ ] Create dashboard to display GitOps status
- [ ] Add panels for:
- Sync status overview (SYNCED vs OUT_OF_SYNC)
- Drift count per repo
- Detailed file list for drifted repos
- Last check timestamp
- Historical trend (if gitops-status-server stores history)
Example dashboard queries provided in [GITOPS_STATUS_API_REFERENCE.md](GITOPS_STATUS_API_REFERENCE.md).
### 9. Cleanup (Optional)
If everything works correctly:
- [ ] Remove old Pushgateway metrics for rsyslog (if no longer needed)
- [ ] Update any alerts/dashboards that used old `gitops_sync_status` metric
- [ ] Document the new JSON status format in team wiki/docs
## Troubleshooting
### Script fails with "command not found: jq"
**Problem:** `jq` is not installed in the Woodpecker container
**Solution:** The `.woodpecker.yml` already includes `apk add --no-cache jq`. Verify the step runs before the script.
### Script fails with "HTTP 404" or "HTTP 500"
**Problem:** gitops-status-server endpoint not implemented or not accessible
**Solution:**
1. Verify gitops-status-server is running: `curl http://gitops-status-server.observability-stack.svc.cluster.local:80/health`
2. Check Kubernetes service: `kubectl get svc -n observability-stack`
3. Implement `/api/status` endpoint using [GITOPS_STATUS_API_REFERENCE.md](GITOPS_STATUS_API_REFERENCE.md)
### Script fails with "No such file or directory: update-gitops-status.sh"
**Problem:** Script not found in workspace
**Solution:** The script is created in the repository root. Verify it's committed to Git and available in the CI workspace.
### Drift not detected when expected
**Problem:** Manual changes not showing up in drift check
**Solution:**
1. Verify changes are to files managed by Git (rsyslog.conf or rsyslog.d/*.conf)
2. Check Ansible playbook output for diff details
3. Verify SSH access to server from CI container
### JSON has empty files array even when drift detected
**Problem:** Script parsing logic not extracting filenames correctly
**Solution:**
1. Check Ansible output format - script expects specific JSON structure
2. Run with `ANSIBLE_STDOUT_CALLBACK=json` to see raw output
3. Update regex patterns in `update-gitops-status.sh` if needed
## Rollback Procedure
If you need to rollback to Pushgateway:
```bash
# Revert to previous commit
git revert HEAD
# Or restore specific files
git checkout HEAD~1 .woodpecker.yml
git checkout HEAD~1 README.md
# Remove new files
git rm update-gitops-status.sh GITOPS_STATUS_*.md MIGRATION_SUMMARY.md
# Commit and push
git commit -m "Rollback to Pushgateway metrics"
git push origin master
```
## Success Criteria
✅ All checks passed when:
- [ ] Woodpecker pipeline completes successfully on push to master
- [ ] JSON status is sent to gitops-status-server after deploy
- [ ] Cron pipeline runs every 2 minutes and sends JSON status
- [ ] Drift is correctly detected and reported in JSON
- [ ] gitops-status-server `/status.json` endpoint returns correct data
- [ ] Grafana dashboard displays rsyslog sync status
- [ ] No errors in Woodpecker logs
- [ ] File-level drift details are visible in Grafana

}
```
## Example Implementation (Python/Flask)
```python
from flask import Flask, request, jsonify
from datetime import datetime
import json
import os
app = Flask(__name__)
# In-memory storage (replace with database in production)
status_data = {}
@app.route('/api/status', methods=['POST'])
def update_status():
"""Receive and store GitOps status updates"""
try:
data = request.get_json()
# Validate required fields
required_fields = ['repo', 'server', 'sync_status', 'drift_count', 'files', 'last_check']
for field in required_fields:
if field not in data:
return jsonify({
'status': 'error',
'message': f'Missing required field: {field}'
}), 400
# Validate sync_status value
if data['sync_status'] not in ['SYNCED', 'OUT_OF_SYNC']:
return jsonify({
'status': 'error',
'message': 'sync_status must be SYNCED or OUT_OF_SYNC'
}), 400
# Create unique key for this repo/server combination
key = f"{data['repo']}:{data['server']}"
# Store the status
status_data[key] = {
'repo': data['repo'],
'server': data['server'],
'sync_status': data['sync_status'],
'drift_count': data['drift_count'],
'files': data['files'],
'last_check': data['last_check'],
'updated_at': datetime.utcnow().isoformat() + 'Z'
}
# Log the update
print(f"Status update: {key} -> {data['sync_status']} (drift_count: {data['drift_count']})")
return jsonify({
'status': 'ok',
'message': 'Status updated successfully'
}), 200
except Exception as e:
print(f"Error processing status update: {e}")
return jsonify({
'status': 'error',
'message': str(e)
}), 500
@app.route('/status.json', methods=['GET'])
def get_status():
"""Serve aggregated status for Grafana Infinity datasource"""
# Convert dict to list for JSON array output
statuses = list(status_data.values())
return jsonify(statuses), 200
@app.route('/health', methods=['GET'])
def health():
"""Health check endpoint"""
return jsonify({
'status': 'healthy',
'timestamp': datetime.utcnow().isoformat() + 'Z',
'tracked_repos': len(status_data)
}), 200
if __name__ == '__main__':
app.run(host='0.0.0.0', port=8080)
```
## Example Implementation (Go)
```go
package main
import (
"encoding/json"
"fmt"
"log"
"net/http"
"sync"
"time"
)
type StatusUpdate struct {
Repo string `json:"repo"`
Server string `json:"server"`
SyncStatus string `json:"sync_status"`
DriftCount int `json:"drift_count"`
Files []File `json:"files"`
LastCheck string `json:"last_check"`
}
type File struct {
Name string `json:"name"`
}
type StoredStatus struct {
StatusUpdate
UpdatedAt string `json:"updated_at"`
}
var (
statusStore = make(map[string]StoredStatus)
storeMutex sync.RWMutex
)
func updateStatusHandler(w http.ResponseWriter, r *http.Request) {
if r.Method != http.MethodPost {
http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
return
}
var status StatusUpdate
if err := json.NewDecoder(r.Body).Decode(&status); err != nil {
http.Error(w, fmt.Sprintf("Invalid JSON: %v", err), http.StatusBadRequest)
return
}
// Validate sync_status
if status.SyncStatus != "SYNCED" && status.SyncStatus != "OUT_OF_SYNC" {
http.Error(w, "sync_status must be SYNCED or OUT_OF_SYNC", http.StatusBadRequest)
return
}
// Store the status
key := fmt.Sprintf("%s:%s", status.Repo, status.Server)
stored := StoredStatus{
StatusUpdate: status,
UpdatedAt: time.Now().UTC().Format(time.RFC3339),
}
storeMutex.Lock()
statusStore[key] = stored
storeMutex.Unlock()
log.Printf("Status update: %s -> %s (drift_count: %d)", key, status.SyncStatus, status.DriftCount)
w.Header().Set("Content-Type", "application/json")
json.NewEncoder(w).Encode(map[string]string{
"status": "ok",
"message": "Status updated successfully",
})
}
func getStatusHandler(w http.ResponseWriter, r *http.Request) {
storeMutex.RLock()
statuses := make([]StoredStatus, 0, len(statusStore))
for _, status := range statusStore {
statuses = append(statuses, status)
}
storeMutex.RUnlock()
w.Header().Set("Content-Type", "application/json")
json.NewEncoder(w).Encode(statuses)
}
func healthHandler(w http.ResponseWriter, r *http.Request) {
storeMutex.RLock()
count := len(statusStore)
storeMutex.RUnlock()
w.Header().Set("Content-Type", "application/json")
json.NewEncoder(w).Encode(map[string]interface{}{
"status": "healthy",
"timestamp": time.Now().UTC().Format(time.RFC3339),
"tracked_repos": count,
})
}
func main() {
http.HandleFunc("/api/status", updateStatusHandler)
http.HandleFunc("/status.json", getStatusHandler)
http.HandleFunc("/health", healthHandler)
log.Println("Starting gitops-status-server on :8080")
log.Fatal(http.ListenAndServe(":8080", nil))
}
```
## Testing the API
### Using curl
**Send a status update:**
```bash
curl -X POST http://localhost:8080/api/status \
-H "Content-Type: application/json" \
-d '{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{"name": "rsyslog.conf"},
{"name": "rsyslog.d/30-lab.conf"}
],
"last_check": "2026-04-21T10:32:15Z"
}'
```
**Get all statuses:**
```bash
curl http://localhost:8080/status.json
```
**Health check:**
```bash
curl http://localhost:8080/health
```
## Grafana Infinity Datasource Configuration
1. Install Grafana Infinity datasource plugin
2. Add new datasource:
- Type: Infinity
- URL: `http://gitops-status-server.observability-stack.svc.cluster.local:80`
3. Create a panel with query:
- URL: `/status.json`
- Parser: Backend
- Format: Table
Example query to show all repos:
```
Source: URL
URL: /status.json
Parser: Backend
Format: Table
Columns:
- repo (string)
- server (string)
- sync_status (string)
- drift_count (number)
- last_check (time)
```
Example query to show drift details:
```
Source: URL
URL: /status.json
Parser: Backend
Format: Table
Root/Rows: $[?(@.drift_count > 0)]
Columns:
- repo (string)
- server (string)
- drift_count (number)
- files (string, JSONata: $join(files.name, ', '))
```
## Notes
- The example implementations use in-memory storage; production should use a database
- Consider adding authentication/authorization for the POST endpoint
- Add monitoring/metrics for the status server itself
- Consider adding TTL/expiration for stale status entries
- The `/status.json` endpoint should support filtering (e.g., by repo or server)

# GitOps Status Fix - Root Cause Analysis and Solutions
## Problem Statement
After deploying configuration changes via the Woodpecker CI pipeline:
1. The status remained **OUT_OF_SYNC** even though deployment succeeded
2. The **files array** in the status JSON was empty/incorrect
## Architecture Overview
### Three Repository Structure:
1. **rsyslog** (this repo)
- Contains Ansible playbooks and .woodpecker.yml
- Runs drift-check.yml to detect configuration drift
- Sends status JSON to gitops-status-server API
2. **gitops-status-api**
- Flask API for storing/retrieving status
- Endpoints:
- POST /api/status - Update status
- GET /api/status - Retrieve status
- GET /status.json - Retrieve status (for Grafana Infinity datasource)
3. **observability-stack**
- ArgoCD Application that deploys gitops-status-server
- Helm chart: `charts/gitops-status-server/`
- Deployment: Single Pod with Flask API container
- Service: ClusterIP on port 80 -> container port 5000
## Root Cause Analysis
### Issue 1: Ansible Callback Breaking Output Parsing
**Problem:**
- `.woodpecker.yml` set `ANSIBLE_STDOUT_CALLBACK=minimal`
- `update-gitops-status.sh` also forced `ANSIBLE_CALLBACKS_ENABLED=""`
- With minimal callback, debug task output format changes:
```
# Expected format (default callback):
ok: [host] => {
"msg": "DRIFTED_FILES=/etc/rsyslog.conf,/etc/rsyslog.d/30-lab.conf"
}
# Actual format (minimal callback):
host | SUCCESS => {
"msg": "DRIFTED_FILES=/etc/rsyslog.conf,/etc/rsyslog.d/30-lab.conf"
}
```
- The `grep` and `sed` parsing in update-gitops-status.sh failed to extract DRIFTED_FILES correctly
**Impact:**
- Even when drift was detected, the files array stayed empty
- `drift_count` was 0 even though `sync_status` was OUT_OF_SYNC
- Grafana showed incomplete information
**Root Cause:**
Inconsistent Ansible callback configuration caused unpredictable debug output formatting.
### Issue 2: Status Shows OUT_OF_SYNC After Successful Deploy
**This is actually CORRECT behavior if drift exists!**
The pipeline flow is:
1. `deploy` step runs `apply.yml` - deploys config to server
2. `update-gitops-status` step runs `drift-check.yml` - checks if server matches Git
If drift-check shows OUT_OF_SYNC after deploy, it means:
- The deployment didn't fully succeed, OR
- There are other differences (permissions, extra files on server, etc.)
**However**, the real issue was:
- We couldn't see WHICH files were drifted (files array was empty)
- This made it impossible to diagnose the root cause
## Solutions Implemented
### Fix 1: Use YAML Callback for Consistent Output
**Changed in:**
- `update-gitops-status.sh`
- `.woodpecker.yml` (update-gitops-status step)
- `.woodpecker.yml` (gitops_sync_check cron step)
**What changed:**
```bash
# BEFORE:
ANSIBLE_CALLBACKS_ENABLED="" \
ANSIBLE_STDOUT_CALLBACK=minimal \
ansible-playbook ...
# AFTER:
ANSIBLE_FORCE_COLOR=false \
ANSIBLE_STDOUT_CALLBACK=yaml \
ansible-playbook ...
```
**Why YAML callback:**
- Consistent, structured output format
- Better for parsing than minimal callback
- Still compact and readable
- Widely supported across Ansible versions
### Fix 2: Improved DRIFTED_FILES Parsing
**Changed in:** `update-gitops-status.sh`
**Old parsing:**
```bash
DRIFTED_FILES_STR=$(echo "$DRIFTED_FILES_STR" | sed 's/.*DRIFTED_FILES=//' | sed 's/\x1b\[[0-9;]*m//g' | sed 's/".*$//' | xargs)
```
Problems:
- Assumed specific ANSI color codes
- Used `xargs` which could break on certain characters
- The `sed 's/".*$//'` would strip everything after first quote
**New parsing:**
```bash
DRIFTED_FILES_STR=$(echo "$DRIFTED_FILES_LINE" | sed 's/.*DRIFTED_FILES=//' | sed 's/^[[:space:]]*//' | sed 's/[[:space:]]*$//' | tr -d '"')
```
Improvements:
- Removes leading/trailing whitespace properly
- Strips quotes without breaking the content
- Works with both YAML and default callback formats
- More robust character handling
### Fix 3: Removed Problematic Environment Variables
**Removed from `.woodpecker.yml`:**
- `ANSIBLE_CALLBACK_WHITELIST: "minimal"` (conflicted with script settings)
- `ANSIBLE_LIBRARY_CACHING: "True"` (not needed, could cause issues)
- `ANSIBLE_CALLBACKS_ENABLED=""` export in commands (broke debug output)
- `ANSIBLE_GATHERING=explicit` export (not related to the issue)
**Kept:**
- `ANSIBLE_HOST_KEY_CHECKING: "False"` (required for CI)
- `ANSIBLE_FORCE_COLOR: "False"` (helps with parsing)
- `ANSIBLE_RETRY_FILES_ENABLED: "False"` (cleaner CI runs)
- `ANSIBLE_UNSAFE_WRITES: "True"` (helps with temp files)
## Testing the Fix
### Expected Behavior After Fix
#### Scenario 1: After Successful Deployment (push to master)
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-22T19:00:00Z"
}
```
#### Scenario 2: When Drift is Detected (cron job or manual server change)
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{"name": "rsyslog.conf"},
{"name": "rsyslog.d/30-lab.conf"}
],
"last_check": "2026-04-22T19:02:00Z"
}
```
### How to Test
1. **Test normal deployment:**
```bash
# Make a change
echo "# Test $(date)" >> files/rsyslog.conf
# Commit and push
git add files/rsyslog.conf
git commit -m "test: verify status tracking"
git push
# Watch pipeline in Woodpecker
# After deploy + update-gitops-status completes:
# - Check Grafana: sync_status should be SYNCED
# - drift_count should be 0
# - files should be []
```
2. **Test drift detection:**
```bash
# SSH to server
ssh rsyslog-lab
# Make a manual change
echo "# Manual drift $(date)" >> /etc/rsyslog.conf
# Wait for cron job (runs every 2 minutes)
# OR manually trigger in Woodpecker
# Check Grafana:
# - sync_status should be OUT_OF_SYNC
# - drift_count should be 1 or more
# - files array should list "rsyslog.conf"
```
3. **Debug mode (if issues persist):**
```bash
# Run locally with debug logging
export KEEP_PLAYBOOK_LOG=true
./update-gitops-status.sh
# Check the output
cat drift-check-output.log | grep -A 5 "DRIFTED_FILES"
```
## Verification Steps
After deploying this fix:
1. ✅ Check that DRIFTED_FILES appears in playbook output
2. ✅ Check that files array is populated when drift exists
3. ✅ Check that sync_status is SYNCED after successful deployment
4. ✅ Check that drift_count matches the number of files
5. ✅ Check that Grafana shows the correct data
6. ✅ Check that cron drift detection works correctly
## Related Files Changed
### rsyslog repo:
- `.woodpecker.yml` - Fixed Ansible callback configuration
- `update-gitops-status.sh` - Improved DRIFTED_FILES parsing
- `GITOPS_STATUS_FIX.md` - This document
### No changes needed in:
- `gitops-status-api` repo (API code is correct)
- `observability-stack` repo (deployment is correct)
- `ansible/playbooks/drift-check.yml` (playbook logic is correct)
## Summary
**What was wrong:**
1. Inconsistent Ansible callback configuration broke debug output parsing
2. DRIFTED_FILES extraction failed silently
3. files array stayed empty even when drift was detected
**What was fixed:**
1. Standardized on YAML callback for consistent output
2. Improved parsing to handle YAML format reliably
3. Removed conflicting environment variables
4. Added better debug logging
**Result:**
- Files array now populates correctly when drift exists
- Sync status accurately reflects server state
- Grafana dashboards show complete information
- Drift detection works end-to-end

# GitOps Status Server Integration
This document explains how the rsyslog repository integrates with gitops-status-server for GitOps monitoring.
## Overview
Instead of pushing simple numeric metrics to Prometheus Pushgateway, the rsyslog repo now sends structured JSON status snapshots to gitops-status-server. This enables richer visualization in Grafana with file-level drift details.
## Architecture
```
┌─────────────────┐ ┌──────────────────────┐ ┌─────────────────────┐
│ Woodpecker CI │ │ gitops-status-server │ │ Grafana │
│ (rsyslog) │────────►│ (Kubernetes) │────────►│ Infinity Plugin │
│ │ POST │ │ GET │ │
│ drift-check │ JSON │ serves /status.json │ │ Dashboard shows │
│ every 2 min │ │ │ │ drift details │
└─────────────────┘ └──────────────────────┘ └─────────────────────┘
```
## API Endpoint
The rsyslog repo sends JSON status updates to:
```
POST http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status
Content-Type: application/json
```
## JSON Payload Format
### When synced (no drift)
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
### When drift detected
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:32:15Z"
}
```
## Field Definitions
| Field | Type | Description |
|----------------|----------|-------------------------------------------------------|
| `repo` | string | Repository name (e.g., "rsyslog") |
| `server` | string | Target server name (e.g., "rsyslog-lab") |
| `sync_status` | string | Either "SYNCED" or "OUT_OF_SYNC" |
| `drift_count` | integer | Number of files that have drifted from Git |
| `files` | array | List of files with drift (empty if synced) |
| `files[].name` | string | Relative path of drifted file |
| `last_check` | string | ISO 8601 timestamp of when drift check was performed |
## When Updates Are Sent
1. **After deployment** (push to master):
- Post-deploy verification runs
- JSON status sent to gitops-status-server
- Pipeline step: `update-gitops-status`
2. **Scheduled cron check** (every 2 minutes):
- Continuous drift monitoring
- JSON status sent to gitops-status-server
- Pipeline step: `gitops_sync_check`
## Error Handling
If the HTTP POST to gitops-status-server fails:
- The pipeline step will fail
- Error message will be logged
- The drift check itself is still performed
- No retry logic (next cron run will retry)
## Script Implementation
The `update-gitops-status.sh` script handles:
1. Running the Ansible drift-check playbook
2. Parsing the output to extract changed file names
3. Building the JSON payload
4. Sending it to gitops-status-server via HTTP POST
## Expected HTTP Response
gitops-status-server should respond with:
- `200 OK` or `201 Created` on success
- `4xx` or `5xx` on error
The rsyslog pipeline treats any 2xx response as success.
## Grafana Visualization
Grafana uses the Infinity datasource plugin to fetch `/status.json` from gitops-status-server and display:
- Current sync status (SYNCED vs OUT_OF_SYNC)
- Number of drifted files
- List of specific files that have drifted
- Last check timestamp
This provides much richer information than a simple numeric metric.

# GitOps Status Server Integration - rsyslog Workflow
## Overview
This document describes the rsyslog repository's integration with **gitops-status-server**, a centralized Kubernetes-based service that manages GitOps status information for multiple repositories.
**Architecture:** Rsyslog repo → generates JSON → POST to gitops-status-server → Grafana reads via Infinity datasource

## Components
### 1. Ansible Playbook: `ansible/playbooks/drift-check.yml`
**Purpose:** Detect configuration drift between Git repository and live server
**Behavior:**
- Runs in check mode (read-only, no actual changes)
- Uses Ansible `copy` module with `check_mode: true`
- Compares controller files (from Git) with server files
- Detects:
- Changes in `/etc/rsyslog.conf`
- Changes in `/etc/rsyslog.d/*.conf` files
- Missing files on server
**Output (debug messages):**
- `DRIFTED_FILES=file1,file2,file3` – Comma-separated list of changed files
- `SYNC_STATUS=SYNCED` or `SYNC_STATUS=OUT_OF_SYNC` – Simple status indicator
**Exit Code:**
- `0` – SYNCED (all tasks pass)
- `non-zero` – OUT_OF_SYNC (fail task reached)
**Example output:**
```
DRIFTED_FILES=/etc/rsyslog.conf,/etc/rsyslog.d/30-lab.conf
SYNC_STATUS=OUT_OF_SYNC
```
---
### 2. Shell Script: `update-gitops-status.sh`
**Purpose:** Orchestrates the complete status update workflow
**Flow:**
1. **Step 1:** Run `drift-check.yml` playbook
- Captures stdout/stderr to temp file
- Stores exit code
2. **Step 2:** Parse playbook output
- Extract `DRIFTED_FILES=...` line
- Parse comma-separated files
- Convert full paths to relative paths
- Determine sync status from exit code
3. **Step 3:** Build JSON payload
- Repo name and server name
- Sync status (SYNCED / OUT_OF_SYNC)
- Drift count (number of changed files)
- Array of changed files with names
- ISO 8601 timestamp
4. **Step 4:** POST JSON to gitops-status-server
- Endpoint: `$GITOPS_STATUS_SERVER_URL/api/status`
- Method: POST
- Content-Type: application/json
- Check HTTP response code (200-299 = success)
**Environment Variables:**
```bash
GITOPS_STATUS_SERVER_URL=http://gitops-status-server.observability-stack.svc.cluster.local:80
REPO_NAME=rsyslog
SERVER_NAME=rsyslog-lab
```
**JSON Payload Generated:**
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
**Exit Codes:**
- `0` – Success (JSON posted to gitops-status-server)
- `1` – Failure (playbook error, network error, etc.)
---
### 3. CI/CD Pipeline: `.woodpecker.yml`
**Two integration points:**
#### a) Post-Deployment (`update-gitops-status` step)
Runs after successful deployment on push to master:
```yaml
update-gitops-status:
depends_on: [deploy]
when:
branch: master
event: push
commands:
- chmod +x update-gitops-status.sh
- ./update-gitops-status.sh
```
**Purpose:** Verify deployment and update status immediately
#### b) Scheduled Drift Check (`gitops_sync_check` cron)
Runs on schedule (every 2 minutes by default):
```yaml
gitops_sync_check:
when:
event: cron
commands:
- chmod +x update-gitops-status.sh
- ./update-gitops-status.sh
# Exit with appropriate code so cron shows as success/failed
- ansible-playbook ... # re-run to determine exit code
```
**Purpose:** Continuous monitoring of server state
**Woodpecker UI Setup:**
1. Go to repository settings
2. Add cron job:
- Name: `gitops_sync_check`
- Branch: `master`
- Schedule: `*/2 * * * *` (every 2 minutes)
---
## Data Flow
### Input (from Ansible)
Drift-check playbook outputs structured markers:
```
...
DRIFTED_FILES=/etc/rsyslog.conf,/etc/rsyslog.d/30-lab.conf
SYNC_STATUS=OUT_OF_SYNC
...
```
### Processing
Shell script parses output:
- Extract drifted files
- Convert paths: `/etc/rsyslog.conf` → `rsyslog.conf`
- Count changed files
- Get current timestamp
### Output (to gitops-status-server)
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:30:00Z"
}
```
### Final Display (in Grafana)
Grafana's Infinity datasource reads `/status.json` from gitops-status-server and displays:
- **Sync Status:** Visual indicator (green ✓ SYNCED / red ✗ OUT_OF_SYNC)
- **Drift Count:** Number of changed files
- **Files:** List of which files are different
- **Last Check:** Timestamp of last drift-check run
---
## Workflow: Manual Server Changes Detection
**Scenario:** Someone manually edits `/etc/rsyslog.conf` directly on the server
**Detection flow:**
1. File is edited on server, Git repo remains unchanged
2. Cron timer triggers `gitops_sync_check` (every 2 minutes)
3. Woodpecker runs `update-gitops-status.sh`
4. Script executes `drift-check.yml` playbook
5. Ansible copy task in check mode detects difference
6. Playbook outputs: `DRIFTED_FILES=/etc/rsyslog.conf`
7. Script parses output and generates JSON
8. Script POSTs JSON to gitops-status-server
9. gitops-status-server updates its `/status.json`
10. Grafana Infinity datasource refreshes
11. Dashboard shows:
- Status: OUT_OF_SYNC
- Drift count: 1
- Files: [rsyslog.conf]
- Last check: <current timestamp>
**Time to detection:** ≤ 2 minutes (next cron run)
---
## Workflow: Deployment & Verification
**Scenario:** Code is pushed to master branch
**Deployment flow:**
1. Push to master triggers Woodpecker pipeline
2. Steps: syntax-check → validate → deploy → update-gitops-status
3. Deploy step runs `ansible/playbooks/apply.yml`
- Copies Git files to server
- Makes rsyslog.conf and rsyslog.d/* files match Git
4. Update-gitops-status step runs:
- Executes `drift-check.yml` again
- Should report no drift (files match Git)
- Generates JSON with `SYNC_STATUS=SYNCED`
- POSTs JSON to gitops-status-server
5. gitops-status-server updates `/status.json` to SYNCED
6. Grafana dashboard immediately shows SYNCED status
**Expected result:** After deployment, status should be SYNCED within minutes
---
## Configuration
### Environment Variables
Set in `.woodpecker.yml`:
```yaml
environment:
# URL of gitops-status-server ClusterIP service
GITOPS_STATUS_SERVER_URL: http://gitops-status-server.observability-stack.svc.cluster.local:80
# Repository identifier (for multi-repo dashboards)
REPO_NAME: rsyslog
# Server identifier (for multi-server dashboards)
SERVER_NAME: rsyslog-lab
# SSH private key (for Ansible to connect to server)
SSH_PRIVATE_KEY: from_secret: SSH_PRIVATE_KEY
# Ansible config location
ANSIBLE_CONFIG: ansible.cfg
```
### Customization
To support multiple servers:
```yaml
gitops_sync_check:
commands:
- bash update-gitops-status.sh # Uses env vars SERVER_NAME
# Or:
- SERVER_NAME=rsyslog-lab-1 bash update-gitops-status.sh
- SERVER_NAME=rsyslog-lab-2 bash update-gitops-status.sh
```

## Advantages Over Pushgateway
| Aspect | Pushgateway | gitops-status-server |
|--------|-------------|----------------------|
| **Infrastructure** | Prometheus + Pushgateway | Single Kubernetes service |
| **Data richness** | Only 0/1 metric | Full JSON with file names, timestamps |
| **Query language** | PromQL (complex) | Simple JSON API (easy) |
| **Grafana integration** | Prometheus datasource | Infinity datasource (JSON) |
| **Multi-repository** | Complex labels | Built-in support |
| **File-level details** | Not available | Full list of changed files |
| **Audit trail** | Metrics only | JSON snapshot with metadata |
---
## Troubleshooting
### JSON not being sent to gitops-status-server
**Check:**
1. Verify gitops-status-server is running:
```bash
kubectl get pod -n observability-stack | grep gitops-status
kubectl logs -n observability-stack <pod-name>
```
2. Test connectivity from Woodpecker:
```bash
# In Woodpecker log, should see:
# ==> Sending status to gitops-status-server...
# ==> Response: HTTP 200
```
3. Check network connectivity:
```bash
# From Woodpecker container, test the endpoint:
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status
```
### Drift not being detected
**Check:**
1. Review drift-check.yml output in Woodpecker logs:
- Should see "✓ SYNCED" or "✗ OUT OF SYNC"
- Should see "DRIFTED_FILES=" line
2. Manual test on server:
```bash
ansible-playbook -i ansible/inventory/hosts.yml ansible/playbooks/drift-check.yml -v
```
3. Check SSH connectivity:
```bash
# Verify SSH key is properly set in Woodpecker
# Check server's rsyslog files are readable:
ssh user@server ls -la /etc/rsyslog.conf /etc/rsyslog.d/
```
### Cron job not running
**Check:**
1. In Woodpecker UI:
- Go to repository settings
- Click "Cron" or look for cron job list
- Verify `gitops_sync_check` is listed with `*/2 * * * *` schedule
2. Check cron execution history:
- Woodpecker should show execution log
- Look for "Step 1/4: Running drift-check playbook..."
3. Manual trigger:
- In Woodpecker UI, try to manually trigger the cron job
- Check logs for errors
### Grafana not showing data
**Check:**
1. Verify gitops-status-server is serving JSON:
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json
```
2. Check Grafana Infinity datasource configuration:
- Datasource URL should point to gitops-status-server
- Test button should show "Data source is working"
3. In dashboard:
- Edit panel
- Query should be: `GET /status.json` (or similar)
- Click "Run query" to test
- Should see JSON response with data
---
## Security Considerations
- ✓ SSH credentials in Woodpecker secrets (not exposed)
- ✓ JSON contains only file names and metadata (not config contents)
- ✓ gitops-status-server only accepts POST from authorized CI/CD
- ✓ No actual rsyslog config files are exposed
- ✓ Network communication is internal (ClusterIP)
---
## Monitoring
### Key Metrics
- **Cron execution:** Every 2 minutes
- **JSON update frequency:** Every 2 minutes (or after deployment)
- **Time to detection:** ≤ 2 minutes for manual drift
- **Time to verification:** Immediate after deployment (post-deploy step)
### Grafana Dashboard
- **Status panel:** Shows SYNCED / OUT_OF_SYNC
- **Drift count:** Number of changed files
- **Changed files table:** Lists affected files
- **Last check:** Timestamp of last check
- **Repo/Server info:** Identifies which repo/server
---
## Examples
### Example 1: Server is synced with Git
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
### Example 2: Manual edit on server
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 1,
"files": [
{ "name": "rsyslog.conf" }
],
"last_check": "2026-04-21T10:32:00Z"
}
```
### Example 3: Multiple files changed
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 3,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" },
{ "name": "rsyslog.d/31-remote.conf" }
],
"last_check": "2026-04-21T10:34:00Z"
}
```
---
## Summary
This integration provides:
- ✓ Real-time drift detection via cron (every 2 minutes)
- ✓ Post-deployment verification
- ✓ File-level granularity (which files changed)
- ✓ Integration with gitops-status-server (centralized service)
- ✓ Grafana Infinity datasource support
- ✓ Clean JSON-based architecture
- ✓ No Pushgateway dependency for this use case
The rsyslog repository is now responsible for producing clean, structured JSON snapshots of its GitOps status, which are consumed by gitops-status-server and displayed in Grafana.

# Migration Summary: Pushgateway → gitops-status-server
This document summarizes the changes made to migrate the rsyslog repository from Pushgateway metrics to JSON status updates for gitops-status-server.
## What Changed
### 1. New Files Created
#### `update-gitops-status.sh`
- Main script that orchestrates the status update flow
- Runs Ansible drift-check playbook
- Parses output to extract changed file names
- Builds structured JSON payload
- Sends JSON to gitops-status-server via HTTP POST
- Handles both SYNCED and OUT_OF_SYNC states
#### `GITOPS_STATUS_INTEGRATION.md`
- Documentation explaining the integration with gitops-status-server
- API endpoint specification
- JSON payload format examples
- Architecture diagram
- Error handling details
### 2. Modified Files
#### `.woodpecker.yml`
**Changes:**
- Updated header comments to reflect new JSON status flow
- Renamed step: `update-sync-metric` → `update-gitops-status`
- Removed Pushgateway environment variable (`PUSHGATEWAY_URL`)
- Added new environment variables:
- `GITOPS_STATUS_SERVER_URL`
- `REPO_NAME`
- `SERVER_NAME`
- Added `jq` package installation for JSON formatting
- Added `bash` package to cron step (required by update-gitops-status.sh)
- Updated both `update-gitops-status` and `gitops_sync_check` steps to call new script
- Removed Pushgateway metric push logic
- Added JSON status update logic
**Step: `update-gitops-status` (formerly `update-sync-metric`)**
- Runs after successful deployment
- Calls `update-gitops-status.sh`
- Always succeeds (status sent regardless of drift)
**Step: `gitops_sync_check`**
- Runs on cron schedule (every 2 minutes)
- Calls `update-gitops-status.sh` to send JSON
- Then checks drift status to determine pipeline success/failure
- Pipeline fails if drift detected (for visibility in Woodpecker UI)
- JSON status always sent before checking drift
#### `README.md`
**Changes:**
- Updated pipeline flow diagrams
- Replaced "Prometheus" with "gitops-status-server" in diagrams
- Removed "sync metric" section
- Added "GitOps status JSON format" section with examples
- Updated pipeline step descriptions to mention JSON status
- Added `update-gitops-status.sh` to repository structure
- Added optional environment variables table
- Updated flow descriptions to explain file-level drift details
### 3. Unchanged Files
The following files remain unchanged and continue to work as before:
- `ansible/playbooks/drift-check.yml` - Still works as-is
- `ansible/playbooks/apply.yml` - Deploy logic unchanged
- `ansible/playbooks/validate.yml` - Validation logic unchanged
- `ansible/inventory/hosts.yml` - Inventory unchanged
- `ansible/inventory/group_vars/all.yml` - Variables unchanged
- `ansible.cfg` - Ansible config unchanged
- `apply.sh` - Local apply script unchanged
- `drift-check.sh` - Local drift check script unchanged
- `files/rsyslog.conf` - Config files unchanged
- `files/rsyslog.d/30-lab.conf` - Config files unchanged
## Behavior Changes
### Before (Pushgateway)
```
drift-check → calculate status (0 or 1) → push to Pushgateway → Prometheus scrapes
```
Output:
```
gitops_sync_status{repo="rsyslog",server="rsyslog-lab"} 1
```
### After (gitops-status-server)
```
drift-check → extract changed files → build JSON → POST to gitops-status-server → Grafana queries
```
Output:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:32:15Z"
}
```
## Benefits
1. **Richer data**: File-level drift information instead of just a binary status
2. **Better visualization**: Grafana can display which specific files have drifted
3. **Detailed tracking**: Know exactly what changed, not just that something changed
4. **Timestamp tracking**: Last check time included in JSON
5. **Drift count**: Quick numeric indicator of severity
6. **Extensible**: JSON format can be easily extended with additional fields
## Migration Checklist
- [x] Create `update-gitops-status.sh` script
- [x] Update `.woodpecker.yml` pipeline
- [x] Update `README.md` documentation
- [x] Create `GITOPS_STATUS_INTEGRATION.md` integration docs
- [x] Remove Pushgateway environment variables
- [x] Add gitops-status-server environment variables
- [x] Update pipeline step names
- [x] Add required packages (jq, bash)
- [x] Test JSON generation logic
- [x] Update flow diagrams
## Testing Recommendations
1. **Test the script locally:**
```bash
export GITOPS_STATUS_SERVER_URL="http://localhost:80"
export REPO_NAME="rsyslog"
export SERVER_NAME="rsyslog-lab"
./update-gitops-status.sh
```
2. **Test in Woodpecker:**
- Trigger a push to master → check `update-gitops-status` step
- Wait for cron run → check `gitops_sync_check` step
- Manually edit a file on server → wait for next cron → verify OUT_OF_SYNC status
3. **Verify gitops-status-server:**
- Check that JSON is received at POST endpoint
- Verify `/status.json` serves the latest data
- Confirm Grafana dashboard displays drift details
## Rollback Plan
If needed, the old Pushgateway approach can be restored by:
1. Reverting `.woodpecker.yml` to previous version
2. Removing `update-gitops-status.sh`
3. Restoring Pushgateway environment variables
All Ansible playbooks remain unchanged, so they will work with either approach.
## Notes
- The rsyslog repo now focuses only on status generation and sending
- gitops-status-server is responsible for serving data to Grafana
- No changes to observability-stack app are needed on the rsyslog side
- This migration is specific to rsyslog repo; other repos can follow same pattern

# Quick Reference: GitOps Status Server Implementation
## What Changed
✅ **Removed:** Pushgateway-based metrics push for sync status
✅ **Added:** JSON-based status updates to gitops-status-server
✅ **Kept:** All existing deploy/apply/drift-check logic
## Files Modified/Created
### Modified
- **`.woodpecker.yml`** – Updated to use `update-gitops-status.sh` instead of Pushgateway
- **`ansible/playbooks/drift-check.yml`** – Added structured file output (`DRIFTED_FILES=...`)
### Created/Used
- **`update-gitops-status.sh`** – Main script that generates JSON and POSTs to gitops-status-server
- **`GITOPS_STATUS_SERVER_INTEGRATION.md`** – Full documentation
## How It Works
```
Cron (every 2 min) or Post-Deploy
↓
update-gitops-status.sh
1. Run drift-check.yml
2. Parse output (DRIFTED_FILES=...)
3. Generate JSON with metadata
4. POST to gitops-status-server/api/status
↓
gitops-status-server receives JSON
└─ Updates /status.json internally
↓
Grafana Infinity datasource
└─ Queries /status.json
└─ Displays sync status, drift count, changed files
```
## JSON Payload Example
### When Synced:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
### When Out of Sync:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:30:00Z"
}
```
## Testing
### Test the script locally:
```bash
# Make script executable
chmod +x update-gitops-status.sh
# Run it (requires SSH key and Ansible configured)
./update-gitops-status.sh
# You should see:
# ==> Running drift-check playbook...
# Step 1/4: Running drift-check playbook...
# Step 2/4: Analyzing drift detection results...
# Step 3/4: Building JSON payload...
# Step 4/4: Sending status to gitops-status-server...
```
### Test drift-check.yml output:
```bash
# Run drift-check playbook to see new structured output
ansible-playbook -i ansible/inventory/hosts.yml ansible/playbooks/drift-check.yml
# You should see debug output like:
# DRIFTED_FILES=/etc/rsyslog.conf,/etc/rsyslog.d/30-lab.conf
# SYNC_STATUS=OUT_OF_SYNC
```
### Test gitops-status-server connectivity:
```bash
# From Woodpecker container or CI environment, test endpoint
curl -X POST \
-H "Content-Type: application/json" \
-d '{"repo":"rsyslog","server":"rsyslog-lab","sync_status":"SYNCED","drift_count":0,"files":[],"last_check":"2026-04-21T10:30:00Z"}' \
http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status
```
## Deployment Steps
### 1. Push changes to Git
```bash
git add .woodpecker.yml ansible/playbooks/drift-check.yml update-gitops-status.sh
git commit -m "refactor: replace pushgateway with gitops-status-server integration"
git push
```
### 2. Verify Woodpecker pipeline
- Pipeline should run automatically on push
- Check logs for successful syntax-check, validate, deploy steps
- New post-deploy step `update-gitops-status` should run after deploy
### 3. Set up Woodpecker cron job
In Woodpecker UI:
1. Go to repository settings
2. Add Cron job:
- Name: `gitops_sync_check`
- Branch: `master`
- Schedule: `*/2 * * * *` (every 2 minutes)
### 4. Verify cron execution
- Wait for next cron trigger (within 2 minutes)
- Check Woodpecker logs for cron execution
- Look for: "Step 1/4: Running drift-check playbook..."
- Should show: "✓ Status update successful (HTTP 200)"
### 5. Verify gitops-status-server receives JSON
```bash
# Check gitops-status-server logs
kubectl logs -n observability-stack -l app=gitops-status-server -f
# Should show POST requests like:
# POST /api/status from Woodpecker
```
### 6. Verify Grafana dashboard
- Open Grafana
- Check Infinity datasource can query gitops-status-server
- Dashboard panel should display:
- Sync status (SYNCED / OUT_OF_SYNC)
- Drift count
- List of changed files
- Last check timestamp
## Environment Variables
In `.woodpecker.yml`:
```yaml
environment:
GITOPS_STATUS_SERVER_URL: http://gitops-status-server.observability-stack.svc.cluster.local:80
REPO_NAME: rsyslog
SERVER_NAME: rsyslog-lab
SSH_PRIVATE_KEY: from_secret: SSH_PRIVATE_KEY
ANSIBLE_CONFIG: ansible.cfg
```
## Troubleshooting
### "HTTP 500" when posting to gitops-status-server
- Check gitops-status-server logs:
`kubectl logs -n observability-stack -l app=gitops-status-server`
- Verify gitops-status-server's API expects POST /api/status
- Check JSON format matches expected schema
### Cron job not running
- In Woodpecker UI, check cron job list in repository settings
- Verify schedule is `*/2 * * * *`
- Check repository has write access to cron jobs
### Drift not detected
- Run drift-check.yml manually:
`ansible-playbook -i ansible/inventory/hosts.yml ansible/playbooks/drift-check.yml -v`
- Check SSH key is properly set in Woodpecker secrets
- Verify server files are readable via SSH
### JSON not being sent
- Check update-gitops-status.sh script is executable:
`ls -la update-gitops-status.sh`
- Check Woodpecker logs for HTTP response code
- Verify gitops-status-server URL is correct:
`curl http://gitops-status-server.observability-stack.svc.cluster.local:80`
## Key Differences from Previous Architecture
| Old (Pushgateway) | New (gitops-status-server) |
|-------------------|---------------------------|
| POST metric to Pushgateway | POST JSON to gitops-status-server |
| Only sync/out-of-sync (0/1) | Rich JSON with file names, count, timestamp |
| Prometheus dependency | Pure JSON API |
| Pushgateway metric format | Grafana Infinity datasource |
| Manual file-level details | Automatic file list in JSON |
## Success Indicators
After deployment:
- ✓ Cron job runs every 2 minutes
- ✓ update-gitops-status.sh script executes
- ✓ JSON POST to gitops-status-server returns HTTP 200
- ✓ gitops-status-server logs show POST requests
- ✓ Grafana dashboard displays sync status and file names
- ✓ Manual changes on server detected within 2 minutes
- ✓ Deployment status updated immediately after push
## Rollback
If needed, revert to Pushgateway:
```bash
# Checkout old .woodpecker.yml version
git checkout HEAD~N .woodpecker.yml
# (Where N is number of commits back)
# Or manually restore Pushgateway step
```
## Monitoring
After deployment, monitor:
1. Cron execution frequency (should be every 2 minutes)
2. HTTP response codes (should be 200)
3. JSON schema consistency
4. Grafana dashboard updates
5. Time to drift detection (should be ≤ 2 minutes)

# rsyslog GitOps # File Deployment & GitOps Management
Manage rsyslog configuration on Linux servers using Git as the single source of truth. A simple, generic Ansible-based system to deploy and manage files on multiple servers using Git as the single source of truth.
If it's not in Git, it doesn't belong on the server.
--- ---
## How it works in one sentence ## Overview
Every change goes through Git. The pipeline makes sure the server always matches what's in Git — and if someone changes the server directly, the system detects it automatically. This repository uses **Ansible** to:
- **Deploy** files from Git to target servers
- **Check Drift** to ensure servers stay in sync with the repository
- **Validate** that deployed files are correct
No rsyslog-specific code. Just simple file deployment that works for any file or service.
--- ---
## The three pipelines ## Project Structure
### 1. Pull Request — "Is this config safe?"
Triggered when you open or update a pull request.
Does **not** touch the live server beyond a basic reachability check.
Does **not** compare the PR content to the server (they're expected to differ before merge).
``` ```

└─ Differs? → send JSON (OUT_OF_SYNC, drift_count: N, files: [...])
│
└─ Update gitops-status-server for Grafana visualization
```
**Pass** = new config is live and the server matches Git.
The sync status JSON is always sent to gitops-status-server regardless of outcome.
---
### 3. Cron — "Is the server still synced?"
Runs automatically every 2 minutes, **even with no new push**.
This is the ArgoCD-style continuous check.
It only reads — never deploys anything.
```
Every 2 minutes (cron)
│
└─► gitops_sync_check SSH to the server, compare every managed config
file against the latest Git commit
│
├─ Matches? → send JSON (SYNCED, drift_count: 0, files: [])
└─ Differs? → send JSON (OUT_OF_SYNC, drift_count: N, files: [...])
│
└─ Update gitops-status-server for Grafana visualization
```
**Why this matters:** if someone edits `/etc/rsyslog.conf` directly on the server
(bypassing Git), the next cron run catches it within 2 minutes and marks OUT_OF_SYNC
with detailed information about which specific files have drifted.

GitOps status JSON format
Instead of simple numeric metrics, this repo now sends rich JSON status data to gitops-status-server:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
When drift is detected:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:32:15Z"
}
```
update-gitops-status.sh Script to generate and send JSON status to gitops-status-server
This JSON is sent to `gitops-status-server` at:
- `http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status`
The gitops-status-server app serves this data via `/status.json` for Grafana Infinity datasource,
providing rich visualization with file-level drift details instead of just a numeric metric
Alert on `gitops_sync_status == 0` in Grafana/Alertmanager.
---
## What drift-check actually compares
The drift-check playbook compares files **from the Woodpecker CI container** (always the latest Git commit) against the live server. It checks:
1. `/etc/rsyslog.conf` — must match `files/rsyslog.conf` in Git
2. `/etc/rsyslog.d/30-lab.conf` — must match `files/rsyslog.d/30-lab.conf` in Git
3. Any file managed by Git must not be missing from the server
Files on the server that are **not** in Git (e.g. `50-default.conf`, `20-ufw.conf`) are ignored — they are owned by the OS and are not our concern.
---
## Repository structure
```
.woodpecker.yml CI pipeline definition
ansible/
inventory/
hosts.yml Server list
group_vars/all.yml Variables (paths, user, etc.)
playbooks/
validate.yml Check rsyslog is running and config loads
apply.yml Deploy config files from Git to server
drift-check.yml Compare Git files to live server (read-only)
files/
rsyslog.conf Main rsyslog config (source of truth)
rsyslog.d/
30-lab.conf Drop-in config for lab logging
``` ```
--- ---
## Woodpecker cron setup ## How It Works (Simple Version)
Go to **Repository Settings → Crons → Add cron**: 1. **You edit the file** in `files/dvir.txt`
2. **You commit to Git** (the source of truth)
3. **Run `apply.yml`** to deploy to all servers
4. **Run `drift-check.yml`** anytime to verify servers match Git
5. **If drift is detected**, run `apply.yml` again to fix it
| Field | Value | That's it!
|----------|---------------------|
| Name | `gitops_sync_check` |
| Branch | `master` |
| Schedule | `*/2 * * * *` |
--- ---
## Required secrets ## Quick Start
Go to **Repository Settings → Secrets**: ### 1. Edit the file you want to deploy
| Name | Description | Open `files/dvir.txt` and add your content:
|----------------------------|-------------------------------------------------------|
| `SSH_PRIVATE_KEY` | Private key to SSH into the server |
## Optional environment variables ```bash
nano files/dvir.txt
```
These can be overridden in the Woodpecker pipeline or `.woodpecker.yml`: To deploy a **different file**, rename it or update the paths in the playbooks.
| Variable | Default | Description | ### 2. Add target servers
|------------------------------|--------------------------------------------------------------------------|---------------------------------------|
| `GITOPS_STATUS_SERVER_URL` | `http://gitops-status-server.observability-stack.svc.cluster.local:80` | URL of gitops-status-server API | Edit `ansible/inventory/hosts.yml`:
| `REPO_NAME` | `rsyslog` | Repository name for JSON status |
| `SERVER_NAME` | `rsyslog-lab` | Server name for JSON status | ```yaml
all:
children:
servers:
hosts:
server1:
ansible_host: 192.168.10.161
server2:
ansible_host: 192.168.10.162
```
### 3. Run the playbooks
#### Deploy the file:
```bash
ansible-playbook ansible/playbooks/apply.yml
```
#### Check if servers are in sync:
```bash
ansible-playbook ansible/playbooks/drift-check.yml
```
#### Validate file on server:
```bash
ansible-playbook ansible/playbooks/validate.yml
```
---
## Playbook Breakdown
### `apply.yml` - Deploy Files
**What it does:**
- Copies `files/dvir.txt` to `/tmp/dvir.txt` on all target servers
- Sets file ownership to `root:root` with permissions `0644`
**When to use:**
- Initial deployment of the file
- After updating the file in Git
**Example:**
```bash
ansible-playbook ansible/playbooks/apply.yml
```
---
### `drift-check.yml` - Detect Configuration Drift
**What it does:**
- Reads the file from the Git repository (local)
- Reads the file from each target server (`/tmp/dvir.txt`)
- Compares the content byte-for-byte
- Reports `SYNCED` or `OUT_OF_SYNC`
**When to use:**
- Verify servers match the repository state
- Detect if someone manually changed the file on the server
- Run periodically (via cron or CI/CD) to monitor compliance
**Example:**
```bash
ansible-playbook ansible/playbooks/drift-check.yml
```
**Output:**
```
✓ dvir.txt is synced # Files match
✗ dvir.txt is out of sync # Files differ or file missing
```
---
### `validate.yml` - Validate Deployment
**What it does:**
- Checks that `/tmp/dvir.txt` exists on the server
- Verifies the file is readable
- Fails if the file is missing or not readable
**When to use:**
- After running `apply.yml` to verify success
- To confirm the deployment was successful
**Example:**
```bash
ansible-playbook ansible/playbooks/validate.yml
```
---
## Configuration
### Inventory: `ansible/inventory/hosts.yml`
Define which servers to manage:
```yaml
all:
children:
servers:
hosts:
server1:
ansible_host: 192.168.10.161
server2:
ansible_host: 192.168.10.162
```
### Global Variables: `ansible/inventory/group_vars/all.yml`
SSH and connection settings:
```yaml
ansible_user: root
ansible_ssh_private_key_file: "~/.ssh/id_rsa"
ansible_ssh_common_args: "-o StrictHostKeyChecking=no"
```
### Ansible Config: `ansible.cfg`
Global Ansible settings (host checking, plugins, etc.)
---
## Workflow Examples
### Example 1: Deploy a new file
```bash
# 1. Edit the file
echo "new config content" > files/dvir.txt
# 2. Commit to Git
git add files/dvir.txt
git commit -m "Update deployment file"
git push
# 3. Deploy to servers
ansible-playbook ansible/playbooks/apply.yml
# 4. Verify success
ansible-playbook ansible/playbooks/validate.yml
```
### Example 2: Monitor for drift (continuous compliance)
```bash
# Run drift check periodically (cron job)
0 */6 * * * cd /path/to/repo && ansible-playbook ansible/playbooks/drift-check.yml
```
### Example 3: Detect and fix manual changes
```bash
# Someone manually edited /tmp/dvir.txt on server1
# Check for drift
ansible-playbook ansible/playbooks/drift-check.yml
# Output: ✗ dvir.txt is out of sync
# Restore from Git
ansible-playbook ansible/playbooks/apply.yml
# Verify it's fixed
ansible-playbook ansible/playbooks/drift-check.yml
# Output: ✓ dvir.txt is synced
```
---
## Prerequisites
- **Ansible** installed on your machine
- **SSH access** to all target servers (password or key-based)
- **Root or sudo access** on target servers (for writing to `/tmp`)
### Install Ansible
```bash
# macOS
brew install ansible
# Ubuntu/Debian
apt-get install ansible
# RHEL/CentOS
yum install ansible
# Python pip
pip install ansible
```
---
## Customization
### Deploy to a different path
Edit `ansible/playbooks/apply.yml`:
```yaml
- name: Copy file to destination
copy:
src: ../../files/dvir.txt
dest: /your/custom/path/filename.txt # ← Change this
owner: root
group: root
mode: "0644"
```
### Deploy multiple files
Add more tasks to `apply.yml`:
```yaml
- name: Copy file 1
copy:
src: ../../files/dvir.txt
dest: /tmp/dvir.txt
- name: Copy file 2
copy:
src: ../../files/another.txt
dest: /tmp/another.txt
```
### Use different target servers
Edit `hosts.yml` and use:
```bash
ansible-playbook ansible/playbooks/apply.yml -i ansible/inventory/hosts.yml --limit "server2"
```
---
## Troubleshooting
### "SSH connection refused"
- Check `ansible_host` is correct in `hosts.yml`
- Verify SSH key in `group_vars/all.yml`
- Test manually: `ssh -i ~/.ssh/id_rsa root@192.168.10.161`
### "Permission denied" on deployment
- Ensure `become: true` is in the playbook
- Verify user has sudo access
- Check SSH key has correct permissions: `chmod 600 ~/.ssh/id_rsa`
### Drift check shows "out of sync" but I didn't change anything
- File permissions or ownership might have changed
- Line endings (CRLF vs LF) might differ
- The server file might be missing
### Can't read file on server
- Check `/tmp/dvir.txt` exists: `ls -la /tmp/dvir.txt`
- Verify permissions: `stat /tmp/dvir.txt`
- Ensure file is readable: `cat /tmp/dvir.txt`
---
## Tips & Best Practices
1. **Always commit before deploying**
- Use Git as the single source of truth
- Never manually edit `/tmp/dvir.txt` on servers
2. **Run drift-check regularly**
- Use cron or CI/CD to monitor compliance
- Alert on `OUT_OF_SYNC` status
3. **Test in dev first**
- Add a `dev` group in `hosts.yml`
- Test playbooks on dev servers before prod
4. **Use version control for everything**
- Keep all changes in Git
- Easy rollback: just revert and re-run `apply.yml`

# rsyslog GitOps: gitops-status-server Integration
## Overview
This repository now uses **gitops-status-server** (a Kubernetes-based service) for GitOps status monitoring, replacing Prometheus Pushgateway.
**Status:** ✅ Ready for deployment
---
## What This Means
### For You (Operator)
- Configure Woodpecker cron job once (5 minutes)
- Cron runs every 2 minutes and checks if rsyslog config on server matches Git
- If changes detected, JSON is automatically sent to gitops-status-server
- Grafana shows:
- **Sync status** (green=SYNCED, red=OUT_OF_SYNC)
- **Drift count** (how many files changed)
- **Changed files** (list of which files are different)
- **Last check** (when drift was last checked)
### For Grafana
- Connects to gitops-status-server via Infinity datasource
- Reads JSON status snapshots
- Displays rich metadata about rsyslog configuration state
### For the System
- Detects manual edits on the server within 2 minutes
- Verifies deployment succeeded immediately after push
- No Pushgateway required
- Clean JSON-based architecture
---
## Quick Start (5 Steps)
### Step 1: Verify Files Are In Place
```bash
# Check these files exist:
ls -la .woodpecker.yml # ✓ Updated
ls -la ansible/playbooks/drift-check.yml # ✓ Enhanced
ls -la update-gitops-status.sh # ✓ New script
```
### Step 2: Make Script Executable
```bash
chmod +x update-gitops-status.sh
git add update-gitops-status.sh
git commit -m "add: gitops-status-server integration script"
git push
```
### Step 3: Verify Pipeline Runs
- Push should trigger Woodpecker pipeline
- New step `update-gitops-status` should execute after `deploy`
- Check logs for: "✓ Status update successful"
### Step 4: Configure Woodpecker Cron Job
In Woodpecker UI:
1. Go to repository
2. Click **Settings** → **Cron**
3. Click **Add Cron**
4. Fill in:
- **Name:** `gitops_sync_check`
- **Branch:** `master`
- **Schedule:** `*/2 * * * *`
5. Click **Save**
### Step 5: Test Cron Job
- Wait max 2 minutes for cron to trigger
- Check Woodpecker logs for cron execution
- Verify gitops-status-server received POST:
```bash
kubectl logs -n observability-stack -l app=gitops-status-server | grep POST
```
---
## How It Works
### Architecture Diagram
```
Every 2 minutes (or after deployment):
Woodpecker
├─ gitops_sync_check or update-gitops-status step
└─ Runs: update-gitops-status.sh
├─ 1. Execute: ansible/playbooks/drift-check.yml
│ └─ Compare Git files vs server files (read-only)
│ └─ Output: DRIFTED_FILES=file1,file2,file3
├─ 2. Parse: Extract changed files and sync status
├─ 3. Generate: JSON payload with metadata
└─ 4. POST: JSON to gitops-status-server/api/status
gitops-status-server (K8s Service)
└─ Receives JSON
└─ Updates /status.json
└─ Serves via HTTP
Grafana
└─ Infinity datasource
└─ Polls /status.json (periodic refresh)
└─ Displays in dashboard panel
```
### Data Flow
**Input:** Ansible drift-check output
```
DRIFTED_FILES=/etc/rsyslog.conf,/etc/rsyslog.d/30-lab.conf
SYNC_STATUS=OUT_OF_SYNC
```
**Output:** JSON sent to gitops-status-server
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:30:00Z"
}
```
**Display:** Grafana dashboard
- 🔴 OUT_OF_SYNC (red card)
- Drift count: 2
- Files: rsyslog.conf, rsyslog.d/30-lab.conf
- Last check: 2026-04-21 10:30 UTC
---
## Files Changed
### `.woodpecker.yml`
**Changes:**
- Renamed step: `update-sync-metric` → `update-gitops-status`
- Changed command: replaced Pushgateway push → `update-gitops-status.sh` script call
- Added environment variables:
- `GITOPS_STATUS_SERVER_URL`
- `REPO_NAME`
- `SERVER_NAME`
- Both `update-gitops-status` (post-deploy) and `gitops_sync_check` (cron) now use the script
### `ansible/playbooks/drift-check.yml`
**Changes:**
- Added file collection: builds list of changed files in `drifted_files` fact
- Added debug output: prints `DRIFTED_FILES=file1,file2,file3` for script parsing
- Added status markers: prints `SYNC_STATUS=SYNCED` or `SYNC_STATUS=OUT_OF_SYNC`
- **No changes to drift detection logic** (fully backward compatible)
### `update-gitops-status.sh` (NEW)
**Purpose:** Orchestrates status generation and delivery
**4 Steps:**
1. Run drift-check.yml
2. Parse output to extract changed files
3. Build JSON payload
4. POST to gitops-status-server/api/status
---
## Testing
### Test 1: Verify script works locally
```bash
# From repo root, with SSH key configured
./update-gitops-status.sh
# Expected output:
# ═══════════════════════════════════════════════════
# Step 1/4: Running drift-check playbook...
# [playbook output...]
# Step 2/4: Analyzing drift detection results...
# Step 3/4: Building JSON payload...
# Generated JSON:
# {
# "repo": "rsyslog",
# ...
# }
# Step 4/4: Sending status to gitops-status-server...
# Response: HTTP 200
# ✓ Status update successful
```
### Test 2: Verify Woodpecker pipeline runs
1. Make a change to a file
2. Push to master branch
3. Woodpecker pipeline should:
- Run syntax-check ✓
- Run validate ✓
- Run deploy ✓
- Run update-gitops-status ✓
4. Check logs for: "✓ Status update successful"
### Test 3: Verify cron job triggers
1. Woodpecker cron job configured for `*/2 * * * *`
2. Wait 2 minutes
3. Check Woodpecker UI for cron execution
4. Check logs for drift-check output
### Test 4: Verify gitops-status-server receives JSON
```bash
# Check gitops-status-server logs
kubectl logs -n observability-stack -l app=gitops-status-server -f
# Should show POST requests:
# POST /api/status - 200 OK
```
### Test 5: Verify Grafana dashboard
1. Open Grafana
2. Check Infinity datasource:
- Should show "Data source is working"
3. Check dashboard panel:
- Should display sync status
- Should show drift count
- Should list changed files (if any)
---
## Troubleshooting
### Issue: Cron job not running
**Check:**
1. Is cron job configured in Woodpecker?
- Go to repo settings → Cron
- Should see `gitops_sync_check` with `*/2 * * * *` schedule
2. Is the schedule active?
- Cron should have triggered at least once
**Fix:**
- Create cron job if missing
- Verify schedule is `*/2 * * * *`
- Check branch is `master`
### Issue: "HTTP 500" or "HTTP 503" when posting
**Check:**
1. Is gitops-status-server running?
```bash
kubectl get pod -n observability-stack | grep gitops-status
```
2. Is it ready?
```bash
kubectl get pod -n observability-stack -o wide | grep gitops-status
```
3. Check logs:
```bash
kubectl logs -n observability-stack -l app=gitops-status-server
```
**Fix:**
- Restart gitops-status-server if needed
- Check error logs for API issues
- Verify /api/status endpoint exists
### Issue: Drift not detected
**Check:**
1. Run drift-check manually:
```bash
ansible-playbook -i ansible/inventory/hosts.yml ansible/playbooks/drift-check.yml -v
```
2. Does it report the correct status?
3. SSH connectivity to server?
**Fix:**
- Check SSH key is set in Woodpecker secrets
- Verify server files are readable: `ssh user@server ls -la /etc/rsyslog.conf`
- Check Ansible inventory is correct
### Issue: JSON not sent (HTTP 000)
**Check:**
1. Is gitops-status-server URL correct?
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80
```
2. Can Woodpecker reach it?
- May be network/DNS issue
**Fix:**
- Check gitops-status-server hostname/port
- Test from Woodpecker container: `curl http://gitops-status-server:80`
- Check Woodpecker network policies
### Issue: Grafana shows "No data"
**Check:**
1. Does Infinity datasource work?
- Go to Data Sources → test
2. Can Grafana reach gitops-status-server?
3. What query is the panel using?
**Fix:**
- Verify datasource URL is correct
- Check query in panel: should be `/status.json` or similar
- Ensure gitops-status-server is returning JSON
---
## Examples
### Example 1: Server is synced
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:32:00Z"
}
```
**Grafana display:**
- 🟢 SYNCED
- Drift: 0
- Files: (empty)
### Example 2: Manual edit on server
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 1,
"files": [
{ "name": "rsyslog.conf" }
],
"last_check": "2026-04-21T10:34:00Z"
}
```
**Grafana display:**
- 🔴 OUT OF SYNC
- Drift: 1
- Files: rsyslog.conf
### Example 3: Multiple files changed after deployment
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:36:00Z"
}
```
**Timeline:**
1. 10:30 - Push to master triggers deploy
2. 10:31 - Deploy completes, files changed
3. 10:31 - update-gitops-status runs, verifies sync
4. 10:31 - JSON sent: SYNCED
5. 10:36 - Grafana shows ✓ SYNCED (5 min later)
---
## Environment Configuration
The following environment variables are set in `.woodpecker.yml`:
```yaml
GITOPS_STATUS_SERVER_URL: http://gitops-status-server.observability-stack.svc.cluster.local:80
REPO_NAME: rsyslog
SERVER_NAME: rsyslog-lab
SSH_PRIVATE_KEY: from_secret: SSH_PRIVATE_KEY
ANSIBLE_CONFIG: ansible.cfg
```
**To customize:**
- Edit `.woodpecker.yml`
- Change environment variables under `update-gitops-status` and `gitops_sync_check` steps
- Push and re-run
---
## Key Features
✅ **Automatic drift detection** – Every 2 minutes
✅ **Post-deployment verification** – Immediate after deploy
✅ **File-level details** – Shows which files changed
✅ **No Pushgateway** – Simplified infrastructure
✅ **Grafana integration** – Infinity datasource (native)
✅ **Audit trail** – JSON snapshots with timestamps
✅ **Multi-server ready** – Structured for scale
---

---
## Next Steps
1. **Verify files are in place:**
```bash
git status
```
2. **Push changes:**
```bash
git push
```
3. **Monitor first pipeline run:**
- Check Woodpecker logs
- Look for `update-gitops-status` step
- Verify HTTP 200 response
4. **Configure cron job:**
- Go to Woodpecker UI
- Add cron: `gitops_sync_check` at `*/2 * * * *`
5. **Test cron execution:**
- Wait 2 minutes
- Check Woodpecker logs
- Verify gitops-status-server receives JSON
6. **Verify Grafana:**
- Check dashboard displays sync status
- Test with manual file edit on server
- Verify detection within 2 minutes
---
## Support
For issues or questions:
1. Check `QUICK_REFERENCE.md` troubleshooting section
2. Review Woodpecker pipeline logs
3. Check gitops-status-server application logs:
```bash
kubectl logs -n observability-stack -l app=gitops-status-server -f
```
4. Test connectivity manually:
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status
```
---
## Summary
You now have a clean, production-ready GitOps status monitoring system that:
- Detects configuration drift every 2 minutes
- Sends rich metadata (file names, timestamps) to gitops-status-server
- Integrates with Grafana via Infinity datasource
- Requires minimal infrastructure (no Pushgateway)
- Works reliably for multi-server deployments
**Status:** ✅ Ready to deploy and use

# Implementation Summary: Pushgateway → gitops-status-server
## Status: ✅ Complete
This document summarizes the refactoring of the rsyslog GitOps monitoring flow to use a centralized gitops-status-server instead of Pushgateway.
---
## What Was Replaced
### Old Architecture (Pushgateway-based)
```
Drift-check runs
↓
Exit code: 0 (synced) or 1 (drift)
↓
Send metric to Pushgateway
↓
Prometheus scrapes Pushgateway
↓
gitops_sync_status{repo="rsyslog",server="rsyslog-lab"} = 0 or 1
↓
Grafana queries Prometheus
↓
Dashboard shows only: SYNCED or OUT_OF_SYNC
```
**Limitations:**
- Only 0/1 metric (no file-level details)
- Requires Pushgateway, Prometheus infrastructure
- Cannot show which files changed
---
### New Architecture (gitops-status-server)
```
Drift-check runs + outputs DRIFTED_FILES=...
↓
update-gitops-status.sh script:
1. Parse changed files
2. Generate JSON
3. POST to gitops-status-server
↓
gitops-status-server
↓
Serves /status.json with rich metadata
↓
Grafana Infinity datasource reads /status.json
↓
Dashboard shows:
- Sync status
- Drift count
- List of changed files
- Last check timestamp
```
**Advantages:**
- ✓ Rich metadata (file-level details)
- ✓ No Pushgateway/Prometheus for this use case
- ✓ Centralized gitops-status-server
- ✓ Easier to audit (JSON snapshot)
- ✓ Better for multi-server/multi-repo
---
## Files Changed
### 1. `.woodpecker.yml` (MAJOR UPDATE)
#### Before (Pushgateway):
```yaml
update-sync-metric:
commands:
- printf 'gitops_sync_status{repo="rsyslog",server="rsyslog-lab"} %s\n' "$STATUS" | \
curl ... --data-binary @- "$PUSHGATEWAY_URL/metrics/job/gitops_rsyslog/..."
```
#### After (gitops-status-server):
```yaml
update-gitops-status:
commands:
- chmod +x update-gitops-status.sh
- ./update-gitops-status.sh
environment:
GITOPS_STATUS_SERVER_URL: http://gitops-status-server.observability-stack.svc.cluster.local:80
REPO_NAME: rsyslog
SERVER_NAME: rsyslog-lab
```
**Changes:**
- Removed `PUSHGATEWAY_URL` environment variable
- Removed metric push command
- Added script execution
- Added `GITOPS_STATUS_SERVER_URL` configuration
- Both `update-gitops-status` and `gitops_sync_check` steps now use the script
---
### 2. `ansible/playbooks/drift-check.yml` (ADDED OUTPUT)
#### Before:
```yaml
- name: Fail if drift detected
ansible.builtin.fail:
msg: "Configuration drift detected..."
when: drift_detected
```
#### After (ADDED before the fail task):
```yaml
# New: Build structured list of changed files
- name: Initialize list of drifted files
ansible.builtin.set_fact:
drifted_files: []
- name: Add main config to drifted files if changed
ansible.builtin.set_fact:
drifted_files: "{{ drifted_files + ['/etc/rsyslog.conf'] }}"
when: main_config_check.changed
# ... (more file collection tasks)
# New: Output structured markers for parsing
- name: Output structured list of drifted files
ansible.builtin.debug:
msg: "DRIFTED_FILES={{ drifted_files | join(',') }}"
when: drift_detected
- name: Output sync status marker
ansible.builtin.debug:
msg: "SYNC_STATUS=OUT_OF_SYNC"
when: drift_detected
```
**Changes:**
- Builds list of drifted files in `drifted_files` fact
- Outputs `DRIFTED_FILES=file1,file2,file3` for script parsing
- Outputs `SYNC_STATUS=SYNCED` or `SYNC_STATUS=OUT_OF_SYNC` markers
- Original drift detection logic unchanged
---
### 3. `update-gitops-status.sh` (CORE SCRIPT)
**New file created:** Orchestrates the entire flow
**Key functionality:**
1. Runs `drift-check.yml` playbook
2. Captures output to temp file
3. Parses `DRIFTED_FILES=...` and `SYNC_STATUS=...` markers
4. Extracts changed file names
5. Converts `/etc/rsyslog.conf` → `rsyslog.conf` (relative paths)
6. Generates JSON with metadata
7. POSTs JSON to gitops-status-server API
**4-step process:**
```
Step 1/4: Running drift-check playbook...
Step 2/4: Analyzing drift detection results...
Step 3/4: Building JSON payload...
Step 4/4: Sending status to gitops-status-server...
```
---
## Generated JSON Format
### Synced State:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
### Out of Sync State:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{ "name": "rsyslog.conf" },
{ "name": "rsyslog.d/30-lab.conf" }
],
"last_check": "2026-04-21T10:30:00Z"
}
```
---
## Data Flow Example
### Scenario: Manual edit on server
1. **Manual change:** Someone edits `/etc/rsyslog.conf` directly on server
2. **Cron trigger:** Scheduled cron job runs (every 2 minutes)
3. **Woodpecker step:** `gitops_sync_check` executes `update-gitops-status.sh`
4. **Drift detection:** `drift-check.yml` runs and detects change
5. **Output parsing:** Script extracts:
- `DRIFTED_FILES=/etc/rsyslog.conf`
- `SYNC_STATUS=OUT_OF_SYNC`
6. **JSON generation:**
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 1,
"files": [{ "name": "rsyslog.conf" }],
"last_check": "2026-04-21T10:32:00Z"
}
```
7. **API POST:** Script POSTs JSON to:
- URL: `http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status`
- Method: POST
- Content-Type: application/json
8. **Server update:** gitops-status-server receives JSON and updates `/status.json`
9. **Grafana update:** Infinity datasource refreshes and displays new status
10. **Result:** Dashboard shows OUT_OF_SYNC with rsyslog.conf listed
**Time to detection:** ≤ 2 minutes
---
## Integration Points
### Woodpecker Events Handled
1. **Pull Request:**
- syntax-check → validate (no drift check)
- No gitops-status update
2. **Push to Master:**
- syntax-check → validate → deploy → **update-gitops-status**
- After deployment, immediately verify sync and update status
3. **Scheduled Cron:**
- **gitops_sync_check** (every 2 minutes by default)
- Continuous drift monitoring
---
## Configuration
### Required Environment Variables
```yaml
GITOPS_STATUS_SERVER_URL: http://gitops-status-server.observability-stack.svc.cluster.local:80
REPO_NAME: rsyslog
SERVER_NAME: rsyslog-lab
SSH_PRIVATE_KEY: from_secret: SSH_PRIVATE_KEY
ANSIBLE_CONFIG: ansible.cfg
```
### Cron Job Setup (Woodpecker UI)
- Name: `gitops_sync_check`
- Branch: `master`
- Schedule: `*/2 * * * *`
---
## Backward Compatibility
- ✓ **Existing deploy logic:** Unchanged (apply.yml still used)
- ✓ **Existing drift detection:** Enhanced (now outputs file names)
- ✓ **PR validation:** Unchanged (syntax-check, validate still used)
- ✓ **Server files:** No changes needed
---
## Security
- ✓ SSH credentials in Woodpecker secrets (not exposed)
- ✓ JSON contains only metadata (file names, counts, timestamps)
- ✓ No actual rsyslog config contents exposed
- ✓ Internal Kubernetes communication (ClusterIP)
- ✓ No Pushgateway exposure
---
## Testing Checklist
- [ ] Cron job is created in Woodpecker
- [ ] Cron job runs on schedule (every 2 minutes)
- [ ] `update-gitops-status.sh` script is executable
- [ ] Script runs successfully (HTTP 200 response)
- [ ] gitops-status-server receives JSON POSTs
- [ ] JSON format matches expected schema
- [ ] Grafana dashboard displays sync status
- [ ] Changed files appear in Grafana panel
- [ ] Manual file edit on server is detected
- [ ] Post-deployment status updates correctly
---
## Migration Steps
1. **Commit and push changes:**
```bash
git add .woodpecker.yml ansible/playbooks/drift-check.yml update-gitops-status.sh
git commit -m "refactor: replace pushgateway with gitops-status-server"
git push
```
2. **Verify pipeline runs successfully**
- Check Woodpecker logs for new steps
3. **Create Woodpecker cron job**
- Name: gitops_sync_check
- Schedule: */2 * * * *
4. **Test cron execution**
- Wait for cron trigger (within 2 minutes)
- Verify JSON is sent to gitops-status-server
5. **Verify Grafana dashboard**
- Confirm Infinity datasource can read gitops-status-server
- Dashboard shows sync status and changed files
6. **Monitor for 24 hours**
- Verify cron runs consistently
- Check for any HTTP errors
- Confirm drift detection works
7. **Decommission Pushgateway** (when confident)
- Stop sending metrics to Pushgateway
- Remove Pushgateway from infrastructure
---
## Rollback Plan
If issues arise:
1. **Revert Woodpecker changes:**
```bash
git revert <commit-hash>
git push
```
2. **Remove cron job:**
- Delete gitops_sync_check from Woodpecker UI
3. **Restore Pushgateway metric push** (if keeping Prometheus monitoring)
---
## Key Improvements
| Metric | Old | New |
|--------|-----|-----|
| Data richness | 0/1 only | JSON with file names |
| Setup complexity | Pushgateway + Prometheus | Single service call |
| Audit trail | Basic | Structured snapshots |
| File-level visibility | None | Complete list |
| Update frequency | After deployment | Every 2 minutes + post-deploy |
| Infrastructure | 2+ services | 1 service (gitops-status-server) |

# GitOps Status Server Helm Chart
A dual-container HTTP server that receives GitOps status updates via POST API and serves status information as JSON for monitoring and observability purposes.
## Overview
This chart deploys a two-container pod:
1. **Nginx** - Serves `/status.json` endpoint for monitoring tools and handles API routing
2. **Flask API** - Processes POST requests to `/api/status` and updates the status JSON
It's designed to be consumed by Grafana's Infinity datasource or other monitoring tools, and to receive updates from CI/CD pipelines like Woodpecker.
## Architecture
```
CI/CD Pipeline (Woodpecker)
↓
POST /api/status
↓
Kubernetes Service (port 80)
↓
Nginx (port 8080)
├─→ /api/status → Proxies to Flask (localhost:5000)
└─→ /status.json → Serves static file
↓
Shared Volume (emptyDir)
├─→ status.json (updated by Flask API)
└─→ Read by Nginx
↓
Grafana Infinity Datasource
Reads /status.json
```
## Features
- **API-driven updates**: POST endpoint for CI/CD pipelines to update status
- **Read-only serving**: Grafana-friendly JSON endpoint
- **Minimal footprint**: nginx-unprivileged + Python-Alpine with minimal resources
- **Secure by default**: Runs as non-root with restricted filesystems
- **Internal only**: ClusterIP service for cluster-internal access
- **ArgoCD compatible**: Init container auto-initializes status from ConfigMap
- **Production-ready**: Includes health checks, security contexts, and resource limits
## Installation
### Using Helm
```bash
# Install with default values
helm install gitops-status ./gitops-status-server
# Install with custom namespace
helm install gitops-status ./gitops-status-server -n observability-stack --create-namespace
# Install with custom values
helm install gitops-status ./gitops-status-server -f custom-values.yaml
```
### Using ArgoCD
Create an Application manifest:
```yaml
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: gitops-status-server
namespace: argocd
spec:
project: default
source:
repoURL: https://github.com/your-org/observability-stack
targetRevision: main
path: gitops-status-server
helm:
values: |
replicaCount: 1
statusJson:
repo: "rsyslog"
server: "rsyslog-lab"
sync_status: "UNKNOWN"
```
## API Endpoints
### GET /status.json
Returns the current status JSON
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json
```
Response:
```json
{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}
```
### POST /api/status
Updates the status with new data
```bash
curl -X POST http://gitops-status-server.observability-stack.svc.cluster.local:80/api/status \
-H "Content-Type: application/json" \
-d '{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "OUT_OF_SYNC",
"drift_count": 2,
"files": [
{"name": "rsyslog.conf"},
{"name": "rsyslog.d/30-lab.conf"}
],
"last_check": "2026-04-21T10:30:00Z"
}'
```
Response (HTTP 200):
```json
{
"success": true,
"message": "Status updated successfully",
"status": { ... }
}
```
### GET /health
Health check endpoint (returns HTTP 200)
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/health
```
### GET /ready
Readiness check (verifies status file is readable)
```bash
curl http://gitops-status-server.observability-stack.svc.cluster.local:80/ready
```
## Integration with Woodpecker
The rsyslog CI/CD pipeline can update status by POSTing to the `/api/status` endpoint:
```bash
#!/bin/bash
GITOPS_STATUS_SERVER_URL="http://gitops-status-server.observability-stack.svc.cluster.local:80"
STATUS_JSON='{
"repo": "rsyslog",
"server": "rsyslog-lab",
"sync_status": "SYNCED",
"drift_count": 0,
"files": [],
"last_check": "2026-04-21T10:30:00Z"
}'
curl -X POST "$GITOPS_STATUS_SERVER_URL/api/status" \
-H "Content-Type: application/json" \
-d "$STATUS_JSON"
```
## Service Discovery
### Internal Kubernetes URL
```
http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json
```
### Port Forwarding (for local testing)
```bash
kubectl port-forward -n observability-stack svc/gitops-status-server 8080:80
# Then access at http://localhost:8080/status.json
```
### NodePort (if service type is changed)
```bash
kubectl patch service -n observability-stack gitops-status-server -p '{"spec":{"type":"NodePort"}}'
# Then access at http://<node-ip>:<node-port>/status.json
```
## Configuration
See `values.yaml` for all configuration options:
- `replicaCount`: Number of replicas
- `image.repository`: Container image
- `image.tag`: Image tag
- `service.type`: Service type (ClusterIP, NodePort, LoadBalancer)
- `service.port`: Service port (default 80)
- `service.targetPort`: Container port (default 8080)
- `resources`: CPU/memory limits and requests
- `statusJson`: Default status JSON values
- `api.image.*`: Python/Flask image configuration
## Grafana Integration
### Infinity Datasource Configuration
1. Install Infinity datasource plugin:
```bash
grafana-cli plugins install yesoreyeram-infinity-datasource
```
2. Add datasource with URL:
```
http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json
```
3. Create panels to visualize:
- `sync_status`: Current synchronization state
- `drift_count`: Number of drifted files
- `files[]`: List of changed files
- `last_check`: Timestamp of last check
### Example Query
```json
{
"url": "http://gitops-status-server.observability-stack.svc.cluster.local:80/status.json",
"format": "json"
}
```
## Security
- Runs as non-root user (UID 101)
- Read-only root filesystem (except for /tmp, /var/cache/nginx, /var/run)
- No privileged capabilities
- Network policies recommended for production
- Service Account with minimal RBAC
## Troubleshooting
### POST Request Returns 400 Error
**Issue**: "Invalid JSON" error
**Solution**: Verify JSON formatting with:
```bash
echo '{...}' | jq '.'
```
### POST Updates Not Appearing in GET Response
**Issue**: Update endpoint returns 200 but status.json isn't updated
**Possible causes**:
- Shared volume permission issue
- API container crashed after POST
- Status file permissions
**Debug**:
```bash
# Check logs
kubectl logs -f deployment/gitops-status-server -c api
kubectl logs -f deployment/gitops-status-server -c nginx
# Check shared volume
kubectl exec deployment/gitops-status-server -c nginx -- ls -la /usr/share/nginx/html/
# Test API directly (port-forward to 5000 first)
kubectl port-forward deployment/gitops-status-server 5000:5000
curl -X POST http://localhost:5000/api/status -H "Content-Type: application/json" -d '{...}'
```
### Connection Refused to gitops-status-server
**Issue**: Woodpecker can't reach the service
**Possible causes**:
- Service in different namespace
- Network policies blocking traffic
- Woodpecker outside cluster
- Service DNS name incorrect
**Solutions**:
- Verify service exists: `kubectl get svc gitops-status-server -n observability-stack`
- Use NodePort for external access (update service type in values)
- Use port-forward as a temporary solution
- Verify network policies allow traffic
## Performance
- **CPU**: 150m limit (100m nginx + 100m API)
- **Memory**: 192Mi limit (64Mi nginx + 128Mi API)
- **Startup time**: ~5 seconds (Flask app install + startup)
- **Update latency**: <100ms (direct file write)
- **Read performance**: <10ms (static file serving)
## License
Same as observability-stack repository
statusJson:
repo: "my-repo"
server: "my-server"
sync_status: "SYNCED"
drift_count: 0
files: []
last_check: "2026-04-21T10:00:00Z"
destination:
server: https://kubernetes.default.svc
namespace: monitoring
syncPolicy:
automated:
prune: true
selfHeal: true
```
## Configuration
### Key Values
| Parameter | Description | Default |
|-----------|-------------|---------|
| `replicaCount` | Number of replicas | `1` |
| `image.repository` | Container image repository | `nginxinc/nginx-unprivileged` |
| `image.tag` | Container image tag | `1.25-alpine` |
| `service.type` | Kubernetes service type | `ClusterIP` |
| `service.port` | Service port | `80` |
| `service.targetPort` | Container target port | `8080` |
| `resources.limits.cpu` | CPU limit | `100m` |
| `resources.limits.memory` | Memory limit | `64Mi` |
| `statusJson` | JSON content to serve | See values.yaml |
### Custom Status JSON
Override the status JSON content in your values:
```yaml
statusJson:
repo: "production-apps"
server: "prod-cluster-01"
sync_status: "SYNCED"
drift_count: 2
files:
- "deployment.yaml"
- "service.yaml"
last_check: "2026-04-21T12:30:00Z"
```
## Usage
### Access the Status Endpoint
From inside the cluster:
```bash
# Using the service DNS name
curl http://gitops-status-server/status.json
# With namespace
curl http://gitops-status-server.monitoring.svc.cluster.local/status.json
```
### Grafana Infinity Datasource Configuration
1. Add an Infinity datasource in Grafana
2. Configure URL: `http://gitops-status-server.monitoring.svc.cluster.local/status.json`
3. Parser: JSON
4. Use fields from the JSON response in your dashboard
Example query fields:
- `sync_status` - Current sync status
- `drift_count` - Number of drifted resources
- `files` - List of changed files
- `last_check` - Timestamp of last check
## Updating Status Data
### Manual Update
Edit the ConfigMap directly:
```bash
kubectl edit configmap gitops-status-server -n monitoring
```
The deployment will automatically roll out with the new content due to the ConfigMap checksum annotation.
### Automated Update via Pipeline
Use `kubectl` in your CI/CD pipeline:
```bash
kubectl create configmap gitops-status-server \
--from-file=status.json=./status.json \
--dry-run=client -o yaml | kubectl apply -f -
```
### ArgoCD Hook (Advanced)
Create a PostSync hook that updates the ConfigMap with current sync status:
```yaml
apiVersion: batch/v1
kind: Job
metadata:
name: update-status
annotations:
argocd.argoproj.io/hook: PostSync
spec:
template:
spec:
containers:
- name: update
image: bitnami/kubectl
command:
- /bin/sh
- -c
- |
# Update status.json with current sync status
kubectl patch configmap gitops-status-server \
--patch '{"data":{"status.json":"..."}}'
restartPolicy: Never
```
## Security Considerations
- Runs as non-root user (UID 101)
- Read-only root filesystem
- No privilege escalation
- Minimal capabilities (all dropped)
- No external network access required
- ClusterIP only (no external exposure)
## Resource Requirements
Minimal resource footprint suitable for small clusters:
- CPU: 50m request / 100m limit
- Memory: 32Mi request / 64Mi limit
## Troubleshooting
### Check pod status
```bash
kubectl get pods -l app.kubernetes.io/name=gitops-status-server
```
### View logs
```bash
kubectl logs -l app.kubernetes.io/name=gitops-status-server
```
### Test endpoint
```bash
kubectl run -it --rm curl --image=curlimages/curl --restart=Never -- \
curl http://gitops-status-server/status.json
```
### Common Issues
**Pod not starting**: Check security context compatibility with your cluster's PSP/PSA policies.
**Empty response**: Verify the ConfigMap is mounted correctly:
```bash
kubectl describe pod -l app.kubernetes.io/name=gitops-status-server
```
**Service not accessible**: Ensure you're accessing from within the cluster and using the correct namespace.

#!/bin/bash
# =============================================================================
# update-gitops-status.sh
#
# Purpose:
# Runs drift-check playbook and generates a JSON status snapshot for
# gitops-status-server. This replaces Pushgateway metric updates with
# richer JSON status suitable for Grafana visualization via Infinity DS.
#
# Flow:
# 1. Execute ansible/playbooks/drift-check.yml (check mode, read-only)
# 2. Capture exit code to determine sync status
# 3. Parse playbook output to extract changed files
# 4. Build structured JSON with metadata
# 5. POST JSON to gitops-status-server API
#
# Usage:
# ./update-gitops-status.sh
#
# Environment Variables:
# GITOPS_STATUS_SERVER_URL - URL of gitops-status-server API
# (default: http://gitops-status-server.observability-stack.svc.cluster.local:80)
# REPO_NAME - Repository name (default: rsyslog)
# SERVER_NAME - Server name (default: rsyslog-lab)
#
# Generated JSON Structure:
# {
# "repo": "rsyslog",
# "server": "rsyslog-lab",
# "sync_status": "SYNCED" or "OUT_OF_SYNC",
# "drift_count": <number>,
# "files": [{"name": "rsyslog.conf"}, {"name": "rsyslog.d/30-lab.conf"}],
# "last_check": "2026-04-21T10:30:00Z"
# }
#
# Exit Codes:
# 0 - Success (JSON posted to gitops-status-server regardless of sync status)
# 1 - Failure (playbook error, network error, JSON post failure, etc.)
