+### Creating and using a Cinder volume for the OpenShift registry
-You can optionally use an existing Cinder volume for the storage of
-your OpenShift registry.
+You can optionally have the playbooks create a Cinder volume and set
+it up as the OpenShift hosted registry.
-To do that, you need to have a Cinder volume (you can create one by
-running:
+To do that you need specify the desired Cinder volume name and size in
+Gigabytes in `inventory/group_vars/all.yml`:
- openstack volume create --size <volume size in gb> <volume name>
+ cinder_hosted_registry_name: cinder-registry
+ cinder_hosted_registry_size_gb: 10
-The volume needs to have a file system created before you put it to
-use. We can do prepare it for you if you put this in inventory/group_vars/all.yml:
+With this, the playbooks will create the volume and set up its
+filesystem. If there is an existing volume of the same name, we will
+use it but keep the existing data on it.
- prepare_and_format_registry_volume: true
-
-**NOTE:** doing so **will destroy any data that's currently on the volume**!
-
-You can also run the registry setup playbook directly:
-
- ansible-playbook -i inventory playbooks/provisioning/openstack/prepare-and-format-cinder-volume.yaml
-
-(the provisioning phase must be completed, first)
+To use the volume for the registry, you must first configure it with
+the OpenStack credentials by putting the following to `OSEv3.yml`:
+ openshift_cloudprovider_openstack_username: "{{ lookup('env','OS_USERNAME') }}"
+ openshift_cloudprovider_openstack_password: "{{ lookup('env','OS_PASSWORD') }}"
+ openshift_cloudprovider_openstack_auth_url: "{{ lookup('env','OS_AUTH_URL') }}"
+ openshift_cloudprovider_openstack_tenant_name: "{{ lookup('env','OS_TENANT_NAME') }}"
-To instruct OpenShift to actually use the volume, you must first configure it
-with the OpenStack credentials by putting the following to `OSEv3.yml`:
-
- ## Openstack credentials
- #openshift_cloudprovider_kind=openstack
- #openshift_cloudprovider_openstack_auth_url=http://openstack.example.com:35357/v2.0/
- #openshift_cloudprovider_openstack_username=username
- #openshift_cloudprovider_openstack_password=password
- #openshift_cloudprovider_openstack_domain_id=domain_id
- #openshift_cloudprovider_openstack_domain_name=domain_name
- #openshift_cloudprovider_openstack_tenant_id=tenant_id
- #openshift_cloudprovider_openstack_tenant_name=tenant_name
- #openshift_cloudprovider_openstack_region=region
-
-Note that these credentials may be different from the ones you used for
-provisioning (say for quota or access control reasons). To use the same
-OpenStack credentials for both, take a look at the `sample-inventory`. It shows
-how to read the values from your shell environment.
-
-Make sure to only set the values you need from (e.g. your keystonerc or
-clouds.yaml). Some of the options ar keystone V2 or V3 specific.
+This will use the credentials from your shell environment. If you want
+to enter them explicitly, you can. You can also use credentials
+different from the provisioning ones (say for quota or access control
+reasons).
**NOTE**: If you're testing this on (DevStack)[devstack], you must
explicitly set your Keystone API version to v2 (e.g.
-`OS_AUTH_URL=http://10.20.30.40/identity/v2.0`) instead of the default
+`OS_AUTH_URL=http://10.34.37.47/identity/v2.0`) instead of the default
value provided by `openrc`. You may also encounter the following issue
with Cinder:

+OpenStack)[openstack] for more information.

+[openstack]: https://docs.openshift.org/latest/install_config/configuring_openstack.html
-You can read the (OpenShift documentation on configuring
-OpenStack)[openstack] for more information.
+Next, we need to instruct OpenShift to use the Cinder volume for it's
+registry. Again in `OSEv3.yml`:
-[openstack]: https://docs.openshift.org/latest/install_config/configuring_openstack.html
+ #openshift_hosted_registry_storage_kind: openstack
+ #openshift_hosted_registry_storage_access_modes: ['ReadWriteOnce']
+ #openshift_hosted_registry_storage_openstack_filesystem: xfs
+The filesystem value here will be used in the initial formatting of
+the volume.

+You can also use a pre-existing Cinder volume for the storage of your
+OpenShift registry.
+
+To do that, you need to have a Cinder volume. You can create one by
+running:
+
+ openstack volume create --size <volume size in gb> <volume name>
+
+The volume needs to have a file system created before you put it to
+use.
+
+As with the automatically-created volume, you have to set up the
+OpenStack credentials in `inventory/group_vars/OSEv3.yml` as well as
+registry values:
+
#openshift_hosted_registry_storage_kind: openstack
#openshift_hosted_registry_storage_access_modes: ['ReadWriteOnce']
#openshift_hosted_registry_storage_openstack_filesystem: xfs
#openshift_hosted_registry_storage_openstack_volumeID: e0ba2d73-d2f9-4514-a3b2-a0ced507fa05
#openshift_hosted_registry_storage_volume_size: 10Gi
-The **Cinder volume ID**, **filesystem** and **volume size** variables must
-correspond to the values in your volume.
+Note the `openshift_hosted_registry_storage_openstack_volumeID` and
+`openshift_hosted_registry_storage_volume_size` values: these need to
+be added in addition to the previous variables.
+
+The **Cinder volume ID**, **filesystem** and **volume size** variables
+must correspond to the values in your volume. The volume ID must be
+the **UUID** of the Cinder volume, *not its name*.
+
+We can do formate the volume for you if you ask for it in
+`inventory/group_vars/all.yml`:
+
+ prepare_and_format_registry_volume: true
+
+**NOTE:** doing so **will destroy any data that's currently on the volume**!
+
+You can also run the registry setup playbook directly:
+
+ ansible-playbook -i inventory playbooks/provisioning/openstack/prepare-and-format-cinder-volume.yaml
+
