this is to allow ceph-authtool to read and write to /var/ and /etc on CentOS Atomic.

 If you want to use "backports", you can set "true" to `ceph_use_distro_backports`.
 Attention, ceph-common doesn't manage backports repository, you must add it yourself.
 
+### For Atomic systems
+
+If you want to run containerized deployment on Atomic systems (RHEL/CentOS Atomic), please copy
+[vagrant.yml.atomic](vagrant_variables.yml.atomic) to vagrant_variables.yml, and copy [group_vars/all.docker](group_vars/all.docker) to `group_vars/all`.
+
+Since `centos/atomic-host` doesn't have spare storage controller to attach more disks, it is likely the first time `vagrant up --provider=virtualbox` runs, it will fail to attach to a storage controller. In such case, run the following command:
+
+```console
+VBoxManage storagectl `VBoxManage list vms |grep ceph-ansible_osd0|awk '{print $1}'|tr \" ' '` --name "SATA" --add sata
+```
+
+then run `vagrant up --provider=virtualbox` again.
