dockerfile-skill

To generate a production-ready Dockerfile for a monorepo, the skill analyzes the workspace layout, detects frameworks like Node.js or Python, and outputs a multi-stage Dockerfile that isolates build dependencies and runtime environments for scalable containerization.

The best way to handle Docker build-time secrets is using build-time environment placeholders. This skill generates Dockerfiles that inject build-time variables automatically, ensuring zero-user-input automation while keeping sensitive data out of the final runtime image.

Dockerfile generation works with Next.js standalone mode and ORM migrations by creating isolated deployment steps. The skill configures the Dockerfile to build the standalone output and integrates a docker-entrypoint script to execute database migrations before application startup.

You can containerize a multi-language repository containing Go binaries and Python services by auto-detecting the language and framework configurations. The skill produces robust multi-stage Dockerfiles that handle distinct build steps and runtime considerations for each service.

To create a .dockerignore and docker-compose.yml, invoke the skill to analyze your project structure. It automatically generates these supporting files alongside the Dockerfile to prevent large unnecessary files from entering the build context and orchestrate external services.
