Spring Boot demonstrates concrete container integrations: Buildpacks and jlink shrink runtime and produce images, with one demo showing 261MB vs 114MB image sizes and startup 1.05s vs 0.07s for jar vs native, and native binaries run inside Docker with no runtime penalty. Testing leverages Docker Compose auto‑injection and Testcontainers with the new service-connection support and a Maven test goal that runs the app with test container config. Live demos also show Docker Model Runner hosting local LLMs (Gemma) and ready/liveness probes wired via Actuator for Kubernetes.
