There are images and containers. You can think about image like as a binary program file. And container is like a running copy of binary. So it is a one-to-many association. Program container should be immutable, so data should be located in other - data-only container.

App docker image is a minimal system (Ubuntu xx.yy LTS) with own node, cron, ps, mongod, runit process supervisor and even sshd. In theory it can run at any x86-64 linux distribution (MacOS, Windows in virtualization).

There is a script dock for easy container management in development. Project located at /app. Supervised startup script can be located at /etc/service/.

./dock pull

Create and start container

./dock run

In development environment it will mount current local directory to /app inside container.

./dock sh

./dock exec ps aux

./dock start

Show container logs (-f for follow)

./dock logs

./dock stop

./dock rm

./dock build

./dock push
