Docker for development

" summary

Explains how a Docker image is a layered snapshot and demonstrates writing Dockerfiles with COPY/ADD, RUN (composer install), ARG/ENV, and an entrypoint+cmd that picks one process; shows docker container run hello-world, the Docker daemon/desktop VM behaviour on Mac, and image caching with buildkit caching and ordering tricks. Covers multi-stage builds to keep artifacts out of final images, bind mounts and the bind mount slowdown on Mac, Compose YAML service names, publishing ports, build secrets and a CI flow that tags a unique build image then promotes it.
