node2pod

A dead simple controller with one job: copy certain labels on kubernetes nodes to all of the pods they are running.

Example deployment

This deployment will project the topology.kubernetes.io/region and topology.kubernetes.io/zone labels from nodes to pods. See deploy/ for complete resources, including RBAC.
