Argo CD App of Apps pattern

Source: interviewintermediate

WHAT IT TESTS: scaling GitOps management. OUTLINE: a parent Application whose manifests are themselves Application resources, so syncing one app declaratively manages many. RED FLAG: confusing it with ApplicationSet or with multi-source apps.

WHAT IT TESTS: whether you can manage many apps declaratively at scale. ANSWER OUTLINE: the App of Apps pattern uses one root Argo CD Application that points at a Git path containing other Application manifests; syncing the root creates and manages all child Applications, which in turn deploy real workloads. It enables one-command cluster bootstrapping, consistent onboarding of new apps via a commit, and clear environment grouping. RED FLAG: conflating it with ApplicationSet generators or thinking it deploys workloads directly.
