Kubernetes Distilled - an in depth guide for the busy Java developer
summary
Covers concrete steps: building Java container images with layer unpacking and smaller bases to reduce image from 488MB to 140MB to ~107MB, pushing to registries, and tagging strategies; local dev flow using scaffold and tilt for hot-reload and Skaffold-like workflows; manifests managed with kustomize, Helm-style charts or server-side dry-run; logging with ELK or Stern, metrics with Prometheus+Grafana, secrets via sealed-secrets or Vault, and PVC/PV patterns for stateful work. Examples live in two repos and there are no live demos during the session.
