docker-build

To create a Dockerfile, this skill inspects your project structure to detect the project type, then generates a Dockerfile configured with multi-stage builds, non-root users, and optimized layer caching to reduce image size.

Optimizing Docker image size is achieved by applying multi-stage builds, configuring non-root users, and optimizing layer caching, which this skill automates by analyzing your project's existing Docker-related files and structure.

Setting up a .dockerignore file involves validating and updating or creating the file to exclude unnecessary files from your builds, which this skill handles automatically as part of the Dockerfile creation or optimization process.

You can optimize an existing Dockerfile; the skill assesses whether a Dockerfile already exists and updates it with best-practice patterns like multi-stage builds and layer optimization without requiring you to start from scratch.

To test a Docker image after building, this skill provides quick test and run commands that you can execute locally to verify the built image functions correctly according to your project's detected configuration.

Dockerfile generation works for various project types by detecting your project's specific structure and requirements, then adjusting the base images and build stages accordingly, whether or not a Dockerfile already exists.
