What is layer caching efficiency?

It is the practice of ordering Dockerfile instructions from least to most frequently changing (e.g., installing OS packages before copying source code) to ensure Docker can reuse cached layers.

Does this skill address container security?

Absolutely. It guides you in implementing non-root users, using .dockerignore to exclude sensitive files, and pinning specific image versions to ensure reproducibility and security.

How does this skill optimize Docker image size?

It implements multi-stage builds to separate build-time dependencies from the runtime environment and recommends minimal base images like Alpine or Distroless to reduce the final footprint.

Can this skill help with Docker Compose configuration?

Yes, it provides patterns for structuring compose files with environment-specific overrides, managing service dependencies via health checks, and setting resource limits.

Optimizes Docker containers using multi-stage builds, efficient layer caching, and secure base image selection for production environments.

Acerca de

The Container Best Practices skill provides expert-level guidance for creating lean, secure, and high-performance container images. It automates the implementation of industry standards such as multi-stage builds to minimize image size, instruction ordering for optimal layer caching, and the selection of minimal base images like Alpine or Distroless. Whether you're configuring complex Docker Compose environments with health checks or implementing BuildKit features for CI/CD pipelines, this skill ensures your container workflow is robust, maintainable, and production-ready.
