summary
Argo CD ApplicationSet is a Kubernetes custom resource plus controller that generates standard Argo CD Applications from a templated application and pluggable generators, eliminating hand-crafted scripts. Generators include list, cluster, git directory, git file, SCM provider, Matrix, and a cluster-decision CR generator; combining git-directory and cluster generators with the Matrix produces N apps × M clusters (example: 5 apps × 10 clusters → 50 generated Applications). Demo shows automatic creation, sync and deletion of child Applications, and a production use case where the git file generator installs Argo Rollouts per cluster; it works and is bundled into OpenShift GitOps.
