Argo CD

A standalone path through Argo CD, the Kubernetes GitOps controller. Beginner covers the GitOps model, the Application resource, sync and health, and the reconcile loop. Intermediate builds real delivery: sync policies and self-heal, sync waves and hooks, app-of-apps and ApplicationSets, and Helm/Kustomize sources. Advanced goes deep: multi-cluster and projects, RBAC and SSO, secrets and image updates, and hardening Argo CD as a privileged platform. Real manifests and CLI output throughout; each level ends with a self-test feeding a rotating final exam.
