CRUX Linux

Installing on CRUX Linux can be handled via the contrib ports from James Mills and are included in the official contrib ports:

docker

The docker port will build and install the latest tagged version of Docker.

Installation

Assuming you have contrib enabled, update your ports tree and install docker (as root):

# prt-get depinst docker

Kernel Requirements

To have a working CRUX+Docker Host you must ensure your Kernel has the necessary modules enabled for the Docker Daemon to function correctly.

Please read the README:

$ prt-get readme docker

The docker port installs the contrib/check-config.sh script provided by the Docker contributors for checking your kernel configuration as a suitable Docker host.

To check your Kernel configuration run:

$ /usr/share/docker/check-config.sh

Starting Docker

There is a rc script created for Docker. To start the Docker service (as root):

# /etc/rc.d/docker start

To start on system boot:

Edit /etc/rc.conf
Put docker into the SERVICES=(...) array after net.

Images

There is a CRUX image maintained by James Mills as part of the Docker "Official Library" of images. To use this image simply pull it or use it as part of your FROM line in your Dockerfile(s).

$ docker pull crux
$ docker run -i -t crux

There are also user contributed CRUX based image(s) on the Docker Hub.

Issues

If you have any issues please file a bug with the CRUX Bug Tracker.
