Which base images does it recommend?

It favors Alpine for Node.js, Go, and Rust, while specifically recommending slim images for Python to avoid common musl compatibility issues.

Does it follow the 12-factor app methodology?

Yes, it ensures all containerized applications follow principles such as explicit dependencies, environment-based configuration, and statelessness.

Does this skill support non-root users?

Yes, the skill enforces mandatory non-root users for all production containers to maximize security and meet compliance requirements.

Is it compatible with orchestration tools?

Yes, it provides expertise for Docker Compose, Skaffold workflows, and OCI-compliant labeling for registries like GHCR.

Can it help reduce my Docker image size?

Absolutely. It utilizes multi-stage builds and minimal base images like Alpine and slim to reduce image sizes by as much as 90-99%.
