Argo CD architectural overview
The shortest authoritative map of Argo CD’s components and the application controller that compares live state with the target state in Git.
Argo CD · Learning path
How does Argo CD reconcile Git with Kubernetes?
A focused path through Argo CD’s component architecture, comparison loop, manifest generation, synchronization, hooks, and resource ordering.
Engineers who want to explain GitOps as a reconciliation system rather than a deployment command wrapped in a user interface.

Stage 1
Understand the reconciliation architecture
Explain how the API server, repository server, and application controller divide manifest generation, state comparison, and synchronization.

Stage 2
Reason about deployment order
Explain sync phases, hooks, waves, health checks, pruning order, and why ordering can stall a synchronization.
Sync phases and waves
Connects PreSync, Sync, PostSync, and SyncFail hooks with wave ordering and the health-based progression of a deployment.
