docker

A production-ready Dockerfile uses a slim base image, installs dependencies efficiently with layer caching, creates a non-root user for security, includes health checks, and supports multi-architecture builds. This Skill generates Dockerfiles adhering to these best practices for optimized, secure images.

Multi-stage builds compile or prepare your application in one stage, then copy only the runtime artifacts into a final lean image. This reduces image size, improves security by excluding build tools, and keeps production containers minimal and faster to deploy.

Containerization wraps your application, dependencies, and runtime into a portable Docker image. Build the image from a Dockerfile, then run it as a container across any platform. This Skill automates the entire workflow: authoring the Dockerfile, building the image, and managing containers.

Yes. Docker Compose defines and runs multi-container applications using a single YAML file. This Skill supports container orchestration with Compose, letting you manage complex deployments with interconnected services, networks, and volumes from one configuration.

A Docker image is a blueprint—a packaged snapshot of code, dependencies, and configuration. A container is a running instance of that image. This Skill handles both: building images from Dockerfiles and managing container lifecycle (creation, execution, cleanup).

Optimization combines slim base images, multi-stage builds, layer caching, minimal dependencies, and non-root users. This Skill applies these techniques automatically to reduce image size, speed up builds, and improve security and runtime performance.
