ArgoCD Application manifest

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: myapp
  namespace: argocd
spec:
  project: default
  source:
    repoURL: https://gitea.local/myorg/myapp
    targetRevision: HEAD
    path: overlays/prod
  destination:
    server: https://kubernetes.default.svc
    namespace: production
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

Push to Git → ArgoCD auto-syncs. No manual kubectl applies needed.
