danielneto/maas repository overview

⁠Docker MAAS

Dockerfile to create a simple MAAS (Metal as a Service) region controller image.

The timezone is set to Sao Paulo.

⁠Disable SELinux

if you have SELinux running, set it to Permissive or Disable it (reboot required)

$ sudo setenforce Permissive

Maybe, there is a way to make it work with SELinux, but I'm lazy ;-)

⁠How to run

Now whitout giving extra privileges:

$ sudo docker run -td --name maas \
--security-opt seccomp=unconfined \
--tmpfs /run --tmpfs /run/lock \
-v /sys/fs/cgroup:/sys/fs/cgroup:ro \
danielneto/maas

But, if you don't care about giving privileges to a container:

$ sudo docker run -td --privileged --name maas -v /sys/fs/cgroup:/sys/fs/cgroup:ro danielneto/maas

⁠Persisting MAAS information

To persist the MAAS information (configurations and databases) you can create
volumes and use them as mount points in your container.
So, even if you remove the container (or it crashes somehow), you keep the
files inside those volumes.

$ sudo docker volume create maas-etc
$ sudo docker volume create maas-var

And then run

$ sudo docker run -td --name maas \
--mount source=maas-etc,target=/etc \
--mount source=maas-var,target=/var \
--security-opt seccomp=unconfined \
--tmpfs /run --tmpfs /run/lock \
-v /sys/fs/cgroup:/sys/fs/cgroup:ro \
