Supported Operating Systems¶
Kolla Ansible supports the following host Operating Systems (OS):
CentOS 7 is no longer supported as a host OS. The Train release supports both CentOS 7 and 8, and provides a route for migration. See the Kolla Ansible Train documentation for information on migrating to CentOS 8.
CentOS Linux 8 (as opposed to CentOS Stream 8) is no longer supported as a host OS. The Victoria release will in future support both CentOS Linux 8 and CentOS Stream 8, and provides a route for migration.
CentOS Stream 9 is supported as a host OS while Kolla does not publish CS9 based images. Users can build them on their own. We recommend using Rocky Linux 9 images instead.
