Why You Should Care About Docker
summary
Demo claims Docker gives fast reproducible dev environments and shows it concretely: a node:8.0 image boots a pristine Linux process in under a second, image build caches skip repeated npm install, the resulting image is ~767 megabytes, apt-get installs like GraphicsMagick live inside the image, nodemon picks up live edits via a mounted volume, and a multi‑service setup via Docker Compose wires the app to MongoDB with persistent volumes so data survives restarts (some live‑demo glitches get fixed).
