Use when asked to dockerize or containerize an app, write or fix a Dockerfile or docker-compose.yml, shrink a large Docker image, speed up slow Docker builds, or run an app with its database locally in containers — Node, Python, Java, Go and others.
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
# Dockerize App ## Overview Produce a small, secure, fast-building image that runs the app exactly as it runs today. Read how the project builds and starts before writing a line, and prove the result by building and running it. ## Method 1. **Discover:** runtime and version (`.nvmrc`, `engines`, `python_requires`, `pom.xml`, `go.mod`), package manager and lockfile, build command, start command, port, required environment variables (`.env.example`), and services it needs (database, cache). **Secrets check:** if a `.env` or similar file in the project holds real-looking credentials (passwords, production hosts, API keys), tell the user in your reply: it must stay out of the image and out of git, and any secret that was ever committed should be rotated. Never use that file in example `docker run --env-file` commands; use `.env.example` as the template. 2. **Write the Dockerfile** with the rules below. Templates per stack are in [templates.md](templates.md). 3. **Write `.dockerignore`** before the first build. 4. **Write `docker-compose.yml`** if the app needs services, with health checks and named volumes. …

How to install
mdr add wst2002/claude-code-skills/dockerize-app@sha256:10fd8ab746f2c897The line at the top of this page pins the label git:20261019.75b8541, 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.
