on YouTube ↗27m

" summary

Explains how to write a federated controller using the informer library, the federated informer helper, and a deletion helper that uses the finalizer API; shows the reconciler functions that list‑and‑copy objects from the Federation API to member clusters and handle cluster join/leave events. Demonstrates a foo controller and kubefed tooling against two GCE clusters, with creates, auto‑recreation after node deletes, and cascading delete working end‑to‑end. Mentions federated ingress, replicas, namespaces, secrets, configmaps and alpha deployments and kubefed becoming beta in 1.6.
