Deployment Checklist
- Review changes:
git diff origin/master - Commit:
git add . && git commit -m "refactor: gitops-status-server integration" - Push:
git push - Verify pipeline runs (check
update-gitops-statusstep) - Create Woodpecker cron job:
gitops_sync_checkat*/2 * * * * - Test cron execution (wait 2 minutes)
- Verify gitops-status-server receives JSON
- Check Grafana dashboard displays status
- Test manual file edit (detect within 2 minutes)
- Monitor for 24 hours
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)
Code Quality
- ✅ Comments explain flow
- ✅ Error handling included
- ✅ Exit codes meaningful
- ✅ No hardcoded paths (environment vars)
- ✅ Ansible playbook backward compatible
- ✅ JSON properly escaped
- ✅ ISO 8601 timestamps
Security
- ✅ SSH credentials in Woodpecker secrets
- ✅ JSON exposes only metadata (no config contents)
- ✅ No sensitive data in logs
- ✅ gitops-status-server internal only (ClusterIP)
- ✅ Network-isolated (Kubernetes)
Performance
- Frequency: Every 2 minutes (cron) + immediate post-deploy
- Duration: ~30 seconds per run (drift-check + JSON POST)
- Data size: ~500 bytes per JSON update
- Network: Internal only (ClusterIP service)
- Load: Minimal (one HTTP POST per cycle)
Success Criteria
✅ Cron job runs every 2 minutes
✅ JSON posted to gitops-status-server with HTTP 200
✅ gitops-status-server receives and stores JSON
✅ Grafana dashboard displays sync status
✅ Changed files listed in Grafana
✅ Manual edits detected within 2 minutes
✅ Post-deploy status updates immediately
✅ No errors in pipeline logs
Rollback (if needed)
# Revert to previous version
git revert HEAD --no-edit
git push
# Remove cron job from Woodpecker UI
