Docker and Podman from Design to Best Practice for Java Developers and Architects
summary
Practical guide to containerizing Java: demonstrates Docker and Podman parity, a working microservices stack (Spring Cloud gateway, config server, Eureka) with three services plus Postgres and H2, Docker Compose files and a preloaded Postgres image that boots with seeded data, and a Jib-built image workflow that sometimes requires Maven plugin fixes. Emphasizes pin base image tags, multi-stage builds to cut image size and build time, use non-root user and externalize config via volumes/env vars; GitHub repo contains runnable code.
