Applying GitOps Principles to Operations

• Introduction:

  • Can we use Git repository as source of truth for operational tasks and reconcile changes with real-world view?
  • GitOps builds upon cloud native principles, providing full history of changes on desired state of environment, system or configuration.

• Using GitOps:

  • Use CI/CD principles to bring changes as pull request from feature branch.
  • Automated process continuously reconciles current state with desired state to update environment.
  • CI/CD workflows can be used to push desired state to environment if agent is not available.

• Governance in GitOps:

  • Good governance practices are crucial in repositories using GitOps principles.
  • Use branch protection rules and repository rules to bring quality into contribution process.
  • Require at least one reviewer and automate quality checks using GitHub Action Workflows.
  • Consider dry-run and smoke test before merging changes to production environment.
