Alpine makes a great docker container, because it is so small and optimized to be run in RAM. It might also might make a good controller for several docker containers with enough RAM. I haven't tested this yet Docker's setup is easy to use from command line. Commands can be run from an interactive shell, or through a configuration file called a "Dockerfile". docker.com has excellent walk-throughs on how to run, pull, setup a container, commit an image, and create a configuration file. hub.docker.com is a freemium setup, where the first private repository is free.

To install from Alpine

apk add docker

The Docker package is in the 'Community' repository, so if the apk add fails with unsatisfiable constraints, you need to edit the /etc/apk/repositories file to add (or uncomment) a line like:


To start the Docker daemon at boot, run:

rc-update add docker boot

then to start the Docker daemon manually, run:

service docker start

How to use docker

The best documentation for how to use Docker and create containers is at the main docker site. Adding anything more to it here would be redundant.


if you create an account at docker.com you can browse through other user's images and learn from the syntax in contributor's dockerfiles.

Official Docker image files are denoted by a blue ribon on the website.
