Can it help with container security?

Yes, it provides specific patterns for running containers as non-root users and setting appropriate resource limits to prevent host system exhaustion.

How does this skill help reduce Docker image size?

It implements multi-stage builds and optimizes Dockerfile command ordering to leverage layer caching while excluding unnecessary files via .dockerignore.

Does it support complex Docker Compose setups?

Absolutely. It assists with version 3+ syntax, networking, volume management, and defining service dependencies using integrated health checks.

What debugging commands does this skill provide?

It guides users through essential diagnostic workflows using commands like docker inspect, logs, and exec to quickly identify and resolve container failures.
