Extended GitOps Patterns
1. Introduction
GitOps is a modern approach to continuous delivery and infrastructure management that uses Git as a single source of truth. Extended GitOps patterns expand upon these principles to provide more advanced solutions that cater to complex environments and multi-cloud strategies.
2. Key Concepts
- **Declarative Infrastructure**: Infrastructure is defined using code, allowing for version control.
- **Continuous Deployment**: Automated deployments triggered by changes in Git repositories.
- **Observability and Monitoring**: Continuous monitoring of infrastructures to ensure they match the declared state.
- **Self-Healing**: Automated correction of any drift from the desired state.
3. Extended Patterns
3.1. Multi-Repository Strategy
Utilizing multiple repositories for different components of your infrastructure allows for better modularity and separation of concerns.
3.2. Pull Request Workflows
Incorporating Pull Requests as a mechanism for approving changes can enhance security and collaboration.
3.3. Policy as Code
Embedding policies directly in the codebase allows for automated compliance checks.
3.4. Drift Detection
Utilizing tools to detect and rectify drift from the desired state automatically.
**Tip**: Use tools like ArgoCD or Flux for implementing these extended patterns effectively.
4. Best Practices
- Use Git as the single source of truth.
- Keep infrastructure definitions modular.
- Automate testing for infrastructure changes.
- Implement robust monitoring and alerting.
- Regularly review and refactor your GitOps processes.
5. FAQ
