Can this skill troubleshoot failing Docker builds?

The skill uses internal diagnostic tools to check the Docker environment, validate Compose configurations, and inspect build history to identify and fix bottlenecks or errors.

Does it support complex Docker Compose setups?

Absolutely. It manages service dependencies with health-based conditions, custom bridge networks for isolation, and resource limits to prevent container sprawl.

How does this skill optimize Docker images?

It implements multi-stage builds, optimizes layer caching by ordering instructions strategically, and utilizes minimal base images like Alpine or Distroless to reduce the final footprint.

Can it help with container security vulnerabilities?

Yes, it enforces non-root user configurations, manages secrets securely without environment variables, and applies the principle of least privilege to container capabilities.
