Coding Kubernetes for kids with Scratch and Che
summary
Custom Scratch blocks talk to Kubernetes via a small Quarkus HTTP service that uses the Fabric8 Kubernetes client, letting Scratch report pod lists, pod counts and pod names and even trigger changes. Blocks are loaded into the Scratch GUI and executed by Scratch VM; the whole project runs inside an Eclipse Che workspace with a devfile (prebuilt node and Quarkus containers), so setup is reproducible and shareable. Demo works live; workspaces provision in about two minutes and are available via the OpenShift Developer Sandbox.
