Flux CD GitOps AI Skill Guide (Claude)

Overview & Engine Architecture

Flux reconciles Kubernetes from Git (or OCI) using composable controllers: source-controller (GitRepository, OCIRepository, HelmRepository, HelmChart), kustomize-controller, helm-controller, and optional image-reflector / image-automation. Unlike a single Application CR, Flux models sources and appliers as separate objects—debug by walking Ready conditions down the chain. Prefer digests in prod overlays; suspend before manual surgery on managed resources.
