Kubernetes for Java Developers
summary
Java now obeys cgroups (Java 10, back‑ported to Java 8u191), avoiding container OOM surprises; demo deploys a Spring Boot monolith with MySQL and two Terracotta cache nodes via Kubernetes using readiness/liveness probes and it works. Builds use daemonless tooling: Jib produces layered images from Maven/Gradle; alternatives include buildpacks. Iteration tools are shown: Skaffold auto-rebuilds and redeploys, Telepresence swaps a local process into the cluster for debugging. Monitoring uses Prometheus + Grafana and a Java operator SDK is used to automate deployments.
