## 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)

# File Deployment & GitOps Management # rsyslog GitOps
A simple, generic Ansible-based system to deploy and manage files on multiple servers using Git as the single source of truth. Manage rsyslog configuration on Linux servers using Git as the single source of truth.
If it's not in Git, it doesn't belong on the server.
--- ---
## Overview ## How it works in one sentence
This repository uses **Ansible** to: 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.
- **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.
--- ---
## Project Structure ## The three pipelines
### 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
``` ```
--- ---
## How It Works (Simple Version) ## Woodpecker cron setup
1. **You edit the file** in `files/dvir.txt` Go to **Repository Settings → Crons → Add cron**:
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
That's it! | Field | Value |
|----------|---------------------|
| Name | `gitops_sync_check` |
| Branch | `master` |
| Schedule | `*/2 * * * *` |
--- ---
## Quick Start ## Required secrets
### 1. Edit the file you want to deploy Go to **Repository Settings → Secrets**:
Open `files/dvir.txt` and add your content: | Name | Description |
|----------------------------|-------------------------------------------------------|
| `SSH_PRIVATE_KEY` | Private key to SSH into the server |
```bash ## Optional environment variables
nano files/dvir.txt
```
To deploy a **different file**, rename it or update the paths in the playbooks. These can be overridden in the Woodpecker pipeline or `.woodpecker.yml`:
### 2. Add target servers | Variable | Default | Description |
|------------------------------|--------------------------------------------------------------------------|---------------------------------------|
Edit `ansible/inventory/hosts.yml`: | `GITOPS_STATUS_SERVER_URL` | `http://gitops-status-server.observability-stack.svc.cluster.local:80` | URL of gitops-status-server API |
| `REPO_NAME` | `rsyslog` | Repository name for JSON status |
```yaml | `SERVER_NAME` | `rsyslog-lab` | Server name for JSON status |
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.)
