Scale GitOps With the Argo CD Agent and Open Cluster Management
summary
Describes using Argo CD Agent with Open Cluster Management (OCM-io) to run a hub‑and‑spoke GitOps pull model that scales to hundreds or thousands of clusters, keeps workload clusters autonomous, and removes stored kubeconfigs. Demonstrates add‑on deployment of only needed Argo controllers to spokes, an OCM placement API to target clusters, and an mTLS certificate scheme with hourly rotation that replaces username/password auth. Shows a live demo creating and deleting a Pac‑Man namespace to prove end‑to‑end reconciliation.
