Can it assist with Docker Compose networking?

Absolutely. It provides patterns for internal network isolation, ensuring sensitive services like databases are not exposed to the frontend or external internet.

What base images does this skill recommend?

It follows a 2025 hierarchy prioritizing high-security, minimal-footprint images like Wolfi/Chainguard, Alpine, and Distroless variants.

How does this skill help reduce Docker image size?

The skill enforces multi-stage builds and layer optimization techniques, ensuring that only necessary runtime dependencies are included in the final production image.

Does it handle Windows-specific Docker issues?

Yes, it includes mandatory guidelines for Windows backslash file paths and provides performance tuning advice for WSL2 and Docker Desktop.
