Multi-cluster, multi-apps, multi-value deployments using Argo CD Application Sets
summary
Shows how Argo CD ApplicationSets generate real Application CRDs to deploy many apps across many clusters with per-cluster overrides, using the git generator plus the cluster generator and matrix composition; a single applied file in the demo creates 13 applications generated from one file. Recommends labeling clusters, using multiple ApplicationSets plus optional app-of-apps, avoiding the Helm sandwich, and using the PR generator to create and destroy preview environments automatically.
