How to Get Started with Docker
summary
Step‑by‑step setup starts with Docker Desktop, then a Dockerfile based on node:12.16.3 that copies package.json, runs npm install and sets CMD to node server.js; image is created with docker build and run with docker run -p 8080:80 -d, verified with docker ps and `docker logs -f`. Image tagging and cloud sharing use pmckee/hello-world and `docker push`/`docker pull`. Local multi‑service development uses Docker Compose that builds the web service and launches mongo:3.6.1 with a named volume; everything runs.
