Safety Practices

⚠️ Production Deployment Guidelines:

1. Manual Sync Only - Require human approval for changes
2. Test in Dev First - Always validate changes in development environment
3. Review Changes - Review Git changes before syncing
4. Tag Releases - Use semantic versioning for releases
5. Monitor Health - Check application and resource health before syncing
6. Plan Upgrades - Schedule major upgrades during maintenance windows

Change Process

1. Create feature branch with changes
2. Test in development environment
3. Create pull request for review
4. Merge to main after approval
5. Review in ArgoCD UI
6. Execute manual sync with proper authorization

Cleanup

kubectl delete -k argocd/prod/
