Docker Best Practices

This one walks you through modern Docker practices with a clear bias toward security and minimal images. You get specific Dockerfile templates for multi-stage builds, the current base image hierarchy (Wolfi/Chainguard over Alpine over distroless), and layer ordering that actually makes sense for caching. It covers the usual production checklist: non-root users, health checks, resource limits, proper logging configs. The .dockerignore template alone will save you from shipping node_modules to production again. Best when you're moving past "it works on my machine" and need containers that won't embarrass you in production. Leans practical over theoretical.
