Containers
Purpose
Build container images that are small, cached effectively, and safe to run — not a 1.2 GB image running as root that rebuilds from scratch every time a source file changes.
When to Use
- Writing or reviewing a Dockerfile.
- Reducing image size or build time.
- Debugging a container that exits, hangs, or behaves differently from local development.
- Hardening images before a security review.
