OSGi with Docker: a powerful way to develop Java systems
summary
A Gradle pipeline compiles OSGi bundles, packs them into p2 features, builds OSGi runtimes and produces Docker images that compose into four containers (nginx frontend, greeter service, login service, DB). The system uses JAX‑RS, JWT tokens, Declarative Services and JUnit system tests; a modified greeter bundle is rebuilt and hot‑installed into the running container without image rebuild, tests rerun, and debugging/attach into the container works. Live bundle updates enable fast inner edit‑compile‑run cycles.
