GitOps Practices

This repository follows GitOps principles:

1. Declarative Configuration

• All configuration is declared in Git (YAML, JSON, etc.)
• No manual configuration changes
• Infrastructure and apps defined as code

2. Git as Single Source of Truth

• Git contains the desired state of the system
• All changes go through Git (PR workflow)
• History is preserved and auditable

3. Automated Deployment

• GitHub Actions automatically deploys on merge to main
• No manual deployment steps
• Consistent, repeatable deployments

4. Continuous Reconciliation

• System automatically syncs to Git state
• Drift detection and correction
• Self-healing infrastructure

Loading

Branch Strategy

• main - Production-ready code, always deployable
• feature/* - New features
• bugfix/* - Bug fixes
• hotfix/* - Urgent production fixes

Required Checks Before Merge

✅ All status checks pass ✅ Code review approved ✅ Conversations resolved ✅ Branch up to date with main

Deployment Flow

1. Commit to main → Auto-deploy to staging
2. Manual approval → Deploy to production
3. Tag creation → Create GitHub release

Security

• Branch protection on main
• Required reviews by code owners
• Signed commits (recommended)
• Secrets stored in GitHub Secrets
• Environment-specific secrets

Monitoring

• GitHub Actions logs
• Deployment status badges
• Environment URLs

Next Steps

• Add ArgoCD for Kubernetes deployments
• Implement FluxCD for continuous reconciliation
• Set up Talos Linux cluster
• Add monitoring and observability
