What is GitOps?

A practice where Git repositories serve as the single source of truth for both application code and infrastructure configuration.

GitOps extends Infrastructure as Code by using Git as the operational mechanism. All changes to infrastructure and applications go through Git pull requests. Automated agents (ArgoCD, Flux) ensure the live system matches the Git repository.

Benefits include audit trail (Git history), rollback (git revert), collaboration (pull requests), and consistency (single source of truth). GitOps is the dominant deployment pattern for Kubernetes-based environments.
