What is GitOps
Managing infrastructure through Git repository
GitOps is a methodology for managing infrastructure and applications where the Git repository is the single source of truth for the entire system.
GitOps Principles
- Declarative — all infrastructure described as code
- Versioned — all changes tracked in Git
- Automated — changes applied automatically
- Self-healing — system returns to target state automatically
Benefits
- Complete history of all changes
- Easy rollback to previous versions
- Built-in audit and compliance
- Simplified onboarding for new developers
- Enhanced security (no direct production access)
Tools
- Argo CD — popular GitOps controller for Kubernetes
- Flux — GitOps operator by Weaveworks
- Jenkins X — CI/CD with GitOps for Kubernetes
- Terraform — Infrastructure as Code
Workflow
- Developer creates Pull Request
- Code Review and automated tests
- Merge to main branch
- GitOps operator syncs cluster
- Monitoring confirms successful deployment
