Run Slackware ARM miniroot filesystem in a Docker container

Using the official Slackware ARM miniroot filesystem from http://ftp.arm.slackware.com/slackwarearm/slackwarearm-devtools/minirootfs/roots/ it's possible to run Slackware ARM OS in a Docker container. This is useful for test-driving the system or trying it out, running processes for testing and development, etc. You should already have Docker installed and running on a host system. Run the Slackware ARM miniroot filesystem in a container as a normal limited user and NOT 'root' user.

git clone https://github.com/Exaga/slackarm-docker

Make a Docker repository directory

mkdir -p slackarm-docker/slackwarearm-current
cd slackarm-docker

Copy the Dockerfile into the repository directory.
