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):

{
  "repo": "rsyslog",
  "server": "rsyslog-lab",
  "sync_status": "SYNCED",
  "drift_count": 0,
  "files": [],
  "last_check": "2026-04-21T10:30:00Z"
}

Template (Out of Sync):

{
  "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"
}

Environment Variables

All set in .woodpecker.yml:

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

Exit Codes

• 0: Success (JSON posted)
• 1: Failure (playbook error, network error, etc.)

---

Ready to Deploy

Prerequisites Met

• ✅ gitops-status-server exists in Kubernetes

• ✅ update-gitops-status.sh – Created and ready
• ✅ Documentation – 5 comprehensive guides

Next Steps

1. Review the changes (run git diff)
2. Test locally if possible (run script)
3. Commit changes to Git
4. Push to trigger pipeline
5. Create Woodpecker cron job
6. Monitor first execution
7. Verify gitops-status-server receives JSON
8. Check Grafana dashboard
