Can I use these patterns for development environments?

Absolutely. The skill includes specific stage naming conventions for 'dev' targets, allowing you to include tools like Xdebug and development dependencies in a single Dockerfile without affecting production.

How does this skill help reduce Docker image size?

It provides patterns to separate build-time tools (like compilers, header files, and Composer) into temporary stages, ensuring only the necessary runtime artifacts and application code are included in the final production image.

What are BuildKit cache mounts?

BuildKit cache mounts allow the Docker daemon to persist directories like the Composer cache or APK cache between builds, drastically reducing the time spent downloading dependencies.

Does it support the latest PHP versions?

Yes, the patterns are specifically updated for PHP 8.4 and use modern Alpine Linux bases to ensure the smallest possible security footprint.

Deployment & DevOps

Optimizes PHP application delivery using multi-stage Docker build patterns for minimal image sizes and faster CI/CD pipelines.

This skill provides a comprehensive knowledge base for implementing professional multi-stage Docker builds specifically tailored for PHP environments. It guides developers through separating dependency installation, extension compilation, and asset building into isolated stages to create lean, production-ready images—often reducing sizes to around 80MB. By leveraging BuildKit cache mounts, strategic layer ordering, and Alpine-based runtimes, it significantly reduces build times and improves security by excluding unnecessary build tools from the final production environment.

Key Features
