Use when you need framework-agnostic Docker and container image guidance for Java projects - Dockerfile design, multi-stage Maven builds, jlink custom runtimes, micro runtime distributions such as Alpaquita, JVM container ergonomics, non-root execution, image metadata, .dockerignore, reproducible builds, vulnerability scanning, SBOM awareness, and production-safe container defaults. This should trigger for requests such as Review Java Dockerfile; Improve Docker image security; Add jlink…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Java container image best practices with Docker Help teams build secure, reproducible, and maintainable **Docker container images** for Java applications without coupling the guidance to Spring Boot, Quarkus, or Micronaut. **What is covered in this Skill?** - Dockerfile structure for Java applications: multi-stage builds, Maven dependency caching, deterministic artifact copies, `jlink` custom runtimes, and `.dockerignore` - Runtime image selection: micro distributions such as Alpaquita, minimal JRE images, pinned versions or digests where appropriate, image labels, and explicit entrypoints - JVM container ergonomics: memory percentage flags, startup behavior, graceful shutdown signals, time zones, and predictable runtime options - Security defaults: non-root users, least privilege, no secrets in layers, reduced package managers, vulnerability scanning, SBOM awareness, and avoiding privileged containers - Operational readiness: health checks when suitable, stdout/stderr logging, port declaration, image size control, build reproducibility, and CI verification …

How to install
mdr add jabrena/plinth/706-technologies-containers-docker@sha256:c6c4d78e93fd746aThe line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
