This weekend I just pushed a new feature in ceph-ansible, which adds the ability to deploy containerized Ceph daemons.
It is quite easy to get going with this, simply do the following:
$ git clone https://github.com/ceph/ceph-ansible
$ cd ceph-ansible
$ cp site-docker.yml.sample site-docker.yml
$ cp vagrant_variables.yml.sample vagrant_variables.yml
$ sed -i "s/docker: false/docker: true/" vagrant_variables.yml
$ sed -i "s/mon_vms: 1/mon_vms: 3/" vagrant_variables.yml
$ vagrant up
...
...
$ vagrant ssh mon0 -c "sudo docker exec ceph-mon0 ceph -s"
cluster 5b1f9b36-c589-42ef-8d19-cb37f3a71e43

Now move away from the keyboard and go grab a coffee.
The process should not last long, most of the time is spent on:
- booting the virtual machines
- install packages
- fetch docker images
More improvement coming soon :)
