GitOps is an operational framework where the entire system state is described declaratively in Git. A GitOps operator (ArgoCD or FluxCD) continuously reconciles the cluster state with the desired state in the repository. Core principles: Declarative -- The entire system is described declaratively (YAML, HCL, etc.) Versioned and immutable -- Git as the single source of truth Pulled automatically -- Agents pull desired state, not pushed by CI Continuously reconciled -- Drift is detected and corrected automatically Developer --> Git Commit --> Git Repo <-- GitOps Agent --> Kubernetes | Reconcile Loop (detect drift) ArgoCD vs FluxCD Feature ArgoCD FluxCD A
