 !!! note
 
     When configuring the ClusterTemplate, you must specify the image used to boot the servers. To do this, register the image with OpenStack Glance and ensure that the os_distro property is set to fedora-coreos. The os_distro attribute must be defined and accurately reflect the distribution used by the cluster driver. This parameter is mandatory and does not have a default value, so it must be specified explicitly. Note that the os_distro attribute is case-sensitive. Currently, only Fedora CoreOS is supported. For more detailed information, refer to the [upstream magnum documentation](https://docs.openstack.org/magnum/latest/user/index.html).
