 # 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.
+https://opengitops.dev/
+
+Key points for a Kubernetes cluster:
+
+The state of the cluster is always described in Git. Git holds everything for the application and not just the source code.
+There is no external deployment system with full access to the cluster. The cluster itself is pulling changes and deployment information.
+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
+
+## Flux
+Prerequisites:
+- Kubernetes Cluster
+-Github (giea, etc) personal access token
