In the ever-evolving world of DevOps, GitOps is changing how teams handle deployments and infrastructure. By using Git as the single source of truth, GitOps enables faster, more reliable, and automated operations.
π GitOps Explained Simply
GitOps is a DevOps practice that uses Git repositories to manage infrastructure and application configurations. All changes to infrastructure are made through Git pull requests (PRs), and a controller automatically syncs the desired state with the actual infrastructure.
π Core Principles of GitOps
- Declarative Infrastructure: Define infrastructure in code (e.g., YAML).
- Version-Controlled: Git tracks every change with history.
- Automatic Sync: Tools like ArgoCD or Flux sync changes to the environment.
- Approval Workflow: PR reviews ensure safe changes.
π§° Popular GitOps Tools
- ArgoCD: Kubernetes-native continuous delivery tool.
- Flux: CNCF GitOps tool that works great with Helm and Kustomize.
- Weave GitOps: UI-based GitOps tool for enterprise use.
β GitOps Benefits
- Faster, safer deployments
- Full audit trail of all infrastructure changes
- Improved security and compliance
- Easy rollback via Git commit history
- Better collaboration using Git workflows
π GitOps vs Traditional CI/CD
Feature | GitOps | Traditional CI/CD |
---|---|---|
Change Trigger | Git commits | Manual or CI server triggers |
Source of Truth | Git repository | CI/CD pipeline configuration |
Sync Method | Pull-based (auto) | Push-based |
π§ Real-World Example
Letβs say you want to deploy a Kubernetes app:
- You update the Kubernetes YAML file in Git.
- Create a PR β team reviews it.
- Once merged, ArgoCD detects the change and deploys it automatically.
- Your cluster now matches the Git state. Done!
