`Project`	Logical grouping of apps
`Sync`	Deploy from Git to cluster
`Auto-Sync`	Automatic deployment
`Self-Heal`	Auto-fix drift from desired state
`Prune`	Delete resources not in Git

Common Commands


        argocd app create myapp

Create application


        argocd app sync myapp

Application YAML

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: myapp
spec:
  project: default
  source:
    repoURL: https://github.com/org/repo
    targetRevision: HEAD
    path: k8s/
  destination:
    server: https://kubernetes.default.svc
    namespace: production
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

Best Practices

Use auto-sync for dev environments
Enable self-heal to maintain desired state
Use app-of-apps pattern for multiple apps
Set sync waves for ordered deployment
