Alice and the lost pod: practical guide to Kubernetes in Scala
summary
Takes Scala code to a live cluster using java kubernetes client, fabric8io and the smaller excuber library, shows pod creation, a Deployment that scales from 3 to 6 replicas, and a NodePort service mapping 8080→3001. Demonstrates listing pods via Scala futures, deleting resources, and defining a CRD called Launcher plus a Launcher resource that spawns a “rocket” — the custom resource controller behavior is exercised and the pod is successfully sent home.
