Argo CD Operations

Argo CD is the reconciler that makes gitops real, but knowing the GitOps model doesn't tell you how to structure hundreds of Applications, order their rollout, or figure out why one has been "Progressing" for twenty minutes. Most Argo CD pain is operational, not conceptual: a bad sync wave ordering, a health check that will never pass, or a manual sync habit that defeats the point of having a reconciler at all.

Sync status tells you if the repo and cluster match; health status tells you if what's running actually works — treat them as two separate questions.

For stuck-sync states, sync waves, and the argocd app command reference, read references/argocd-troubleshooting.md.

1. Manage many Applications with app-of-apps or ApplicationSets
