gluster in a container. or giac?

Install the systemd units and run the following:

systemctl enable glusterd
systemctl start glusterd

If you already have a node or more operational, you will want to join this node as a peer. Run the following on an existing node.

docker exec -ti glusterd gluster peer probe <hostname-or-ip-of-new-node>

To create a volume create your bricks in /srv/gluster/bricks/brickN/brick and run the following on any joined node (my example is called absol and the volume is named gvol0):

docker exec -ti glusterd gluster volume create gvol0 absol:/srv/gluster/bricks/brick1/brick absol:/srv/gluster/brick2/brick
docker exec -ti glusterd gluster volume start gvol0

To mount a volume, create files like example/mnt-gvol.* in /etc/systemd/system.

You will also need to add the mount.glusterfs-docker command to /sbin:

docker run -i jamesandariese/glusterfs:6.2 cat /sbin/mount.glusterfs-docker > /sbin/mount.glusterfs-docker
chmod +x /sbin/mount.glusterfs-docker

In the example, volumeName would be gvol0 and it will be mounted at /mnt/gvol0.
