How does this skill improve PHP Docker build speeds?

It implements specialized techniques like BuildKit cache mounts for Composer, parallelizes dependency stages, and optimizes the order of commands to maximize layer reuse.

What kind of time savings can I expect?

Typical optimizations result in cold builds being 60% faster and warm builds (where only source code changed) finishing in seconds rather than minutes.

Can it help reduce the size of the Docker build context?

Absolutely. It identifies unnecessary files and generates an efficient .dockerignore file, which can often reduce context upload size by over 95%.

Does it work with both Alpine and Ubuntu-based images?

Yes, it provides optimized patterns for both apk (Alpine) and apt-get (Debian/Ubuntu) package managers, including virtual dependency management to keep images slim.

Deployment & DevOps

Optimizes Docker build performance for PHP applications using advanced caching, parallelization, and layer management.

This skill enables Claude to analyze and refactor Dockerfiles to drastically reduce build times for PHP projects. By implementing modern BuildKit features like cache mounts, optimizing layer ordering based on change frequency, and configuring parallel multi-stage builds, it transforms slow, monolithic image builds into efficient, high-performance pipelines. It specifically addresses PHP-specific bottlenecks such as extension compilation and Composer dependency management, helping developers achieve up to 80% faster build cycles.
