What is the reconciliation loop and how often does ArgoCD run it?

Advanced

Answer

The reconciliation loop continuously compares desired (Git) vs live (cluster) state and acts on differences. ArgoCD polls Git on an interval (default ~3 minutes) and can react instantly to webhooks; it also watches cluster resources. Reconciliation computes the diff, updates sync/health status, and applies changes if auto-sync is enabled.
# argocd-cm: change polling interval
data:
  timeout.reconciliation: 180s
Real-world example A Git webhook triggers ArgoCD to reconcile immediately on merge instead of waiting for the next poll cycle.
