 # GitOps
-> A set of "best practices" where the entire code delivery process is controlled via Git,
-including infrastructure and application definition as code and automation to complete updates
-and rollbacks.
-
-The key GitOps Principles
-- The entire system (infrastructure and applications) is described declaratively.
-- The canonical desired system state is versioned in Git.
-- Changes approved are automated and applied to the system.
-- Software agents ensure correctness and alert on divergence.

-Key points for a Kubernetes cluster:
-1. The state of the cluster is always described in Git. Git holds everything for the application
-and not just the source code.
-2. There is no external deployment system with full access to the cluster. The cluster itself
-is pulling changes and deployment information.
-3. The GitOps controller is running in a constant loop and always matches the Git state with the
-cluster state (reconciliation loop).

-## flux vs ArgoCD
-Flux is more CLI Driven
-ArgoCD has a richer GUI
