+OpenStack Flavors
+=================
+
+This role can be used to register flavors in Nova using the
+`openstack.cloud.compute_flavor` module.
+
+Requirements
+------------
+
+The OpenStack Nova API should be accessible from the target host.
+
+Role Variables
+--------------
+
+`os_flavors_venv` is a path to a directory in which to create a
+virtualenv.
+
+`os_flavors_auth_type` is an authentication type compatible with
+the `auth_type` argument of `openstack.cloud` Ansible modules.
+
+`os_flavors_auth` is a dict containing authentication information
+compatible with the `auth` argument of `openstack.cloud` Ansible modules.
+
+`os_flavors_cacert` is an optional path to a CA certificate bundle.
+
+`os_flavors_interface` is the endpoint URL type to fetch from the service
+catalog. Maybe be one of `public`, `admin`, or `internal`.
+
+`os_flavors` is a list of Nova flavors to register. Each item should be a dict
+containing the items 'name', 'ram', 'disk', and 'vcpus'. Optionally, the dict
+may contain 'ephemeral', 'flavorid', 'rxtx_factor' and 'swap' items.
+Optionally, the dict may also contain an item 'extra_specs', which is a dict of
+metadata to attach to the flavor object.
+
+Dependencies
+------------
+
+This role depends on the `stackhpc.openstack.os_openstacksdk` role.
+
+Example Playbook
+----------------
+
+The following playbook registers a Nova flavor.
+
+    ---
+    - name: Ensure Nova flavors are registered
+      hosts: localhost
+      roles:

+            password: <keystone password>
+            auth_url: <keystone auth URL>
+          os_flavors:

+              disk: 1024

+                hw:cpu_policy: "dedicated"
+                hw:numa_nodes: "1"
