Managing Thousands of Clusters and Their Workloads with Flux

summary
Claim: a management cluster uses Flux plus OPA Gatekeeper and Cluster API to declare and operate thousands of clusters from Git, bootstrapping Flux, creating a secret with kubeconfig, and applying Flux customizations targeting remote clusters that pull three repos per cluster: common, workspace, and cluster-specific. Demo shows attaching/detaching clusters (detaching removes applied resources but leaves Flux), tenant isolation via per-tenant Git repositories and workspaces, and recommends staged rollouts to avoid blast radius while noting repo-conflict and override issues remain.
