Hands-on Intro to Kubernetes (and OpenShift) for JS Developers
summary
Live lab that authenticates to a 19-node cluster, uses oc and kubectl, and builds a Node.js image with nodejs source-to-image from a Git repo; it deploys a web app, exposes a route, scales to five replicas, deletes pods to prove automatic recovery, performs a rolling update to a v1 image and rolls back, and streams build logs and watches status (the API populates ~130 extra lines of status). Also demonstrates oc rsync/odo for iterative local edits; everything shown works end to end.
