In this patch: - adjusted VersionsController to return only v3 - removed cinder.api.v2.router - adjustments to cinder.tests.unit.api.contrib to use /v3 only - moved cinder.api.v2.snapshot_metadata (and tests) to cinder.api.v3 - moved cinder.api.v2.types (and view, tests) to cinder.api.v3 - updated versions response in api-ref - removed unnecessary config option - updated various sample config files - removed experimental tempest-cinder-v2-api job - updated some docs - updated non-voting rally job config Some cinder.api.v2 modules are left because the v3 classes depend on them, but with the v2 router removed, these are unreachable via the /v2 path. Depends-on: https://review.opendev.org/c/openstack/rally-openstack/+/794891 (changes rally to use Block Storage API v3) Depends-on: https://review.opendev.org/c/openstack/requirements/+/794894 (corrects regression in upper-constraint on Sphinx) Change-Id: I2093d77db9beec7543c7524d2cd273e79dd5fd5d

Install and configure controller node
This section describes how to install and configure the Block Storage service, code-named cinder, on the controller node. This service requires at least one additional storage node that provides volumes to instances.
Prerequisites
Before you install and configure the Block Storage service, you must create a database, service credentials, and API endpoints.
To create the database, complete these steps:
Use the database access client to connect to the database server as the
root
user:# mysql
Create the
cinder
database:MariaDB [(none)]> CREATE DATABASE cinder;
Grant proper access to the
cinder
database:MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \ IDENTIFIED BY 'CINDER_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \ IDENTIFIED BY 'CINDER_DBPASS';
Replace
CINDER_DBPASS
with a suitable password.Exit the database access client.
Source the
admin
credentials to gain access to admin-only CLI commands:$ . admin-openrc
To create the service credentials, complete these steps:
Create a
cinder
user:$ openstack user create --domain default --password-prompt cinder User Password: Repeat User Password: +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 9d7e33de3e1a498390353819bc7d245d | | name | cinder | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+
Add the
admin
role to thecinder
user:$ openstack role add --project service --user cinder admin
Note
This command provides no output.
Create the
cinderv3
service entity:$ openstack service create --name cinderv3 \ --description "OpenStack Block Storage" volumev3 +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Block Storage | | enabled | True | | id | ab3bbbef780845a1a283490d281e7fda | | name | cinderv3 | | type | volumev3 | +-------------+----------------------------------+
Note
Beginning with the Xena release, the Block Storage services require only one service entity. For prior releases, please consult the documentation for that specific release.
Create the Block Storage service API endpoints:
$ openstack endpoint create --region RegionOne \ volumev3 public http://controller:8776/v3/%\(project_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | 03fa2c90153546c295bf30ca86b1344b | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | ab3bbbef780845a1a283490d281e7fda | | service_name | cinderv3 | | service_type | volumev3 | | url | http://controller:8776/v3/%(project_id)s | +--------------+------------------------------------------+ $ openstack endpoint create --region RegionOne \ volumev3 internal http://controller:8776/v3/%\(project_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | 94f684395d1b41068c70e4ecb11364b2 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | ab3bbbef780845a1a283490d281e7fda | | service_name | cinderv3 | | service_type | volumev3 | | url | http://controller:8776/v3/%(project_id)s | +--------------+------------------------------------------+ $ openstack endpoint create --region RegionOne \ volumev3 admin http://controller:8776/v3/%\(project_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | 4511c28a0f9840c78bacb25f10f62c98 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | ab3bbbef780845a1a283490d281e7fda | | service_name | cinderv3 | | service_type | volumev3 | | url | http://controller:8776/v3/%(project_id)s | +--------------+------------------------------------------+
Install and configure components
Install the packages:
# apt install cinder-api cinder-scheduler
Edit the
/etc/cinder/cinder.conf
file and complete the following actions:In the
[database]
section, configure database access:[database] # ... connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
Replace
CINDER_DBPASS
with the password you chose for the Block Storage database.In the
[DEFAULT]
section, configureRabbitMQ
message queue access:[DEFAULT] # ... transport_url = rabbit://openstack:RABBIT_PASS@controller
Replace
RABBIT_PASS
with the password you chose for theopenstack
account inRabbitMQ
.In the
[DEFAULT]
and[keystone_authtoken]
sections, configure Identity service access:[DEFAULT] # ... auth_strategy = keystone [keystone_authtoken] # ... www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = cinder password = CINDER_PASS
Replace
CINDER_PASS
with the password you chose for thecinder
user in the Identity service.Note
Comment out or remove any other options in the
[keystone_authtoken]
section.In the
[DEFAULT]
section, configure themy_ip
option to use the management interface IP address of the controller node:[DEFAULT] # ... my_ip = 10.0.0.11
In the
[oslo_concurrency]
section, configure the lock path:[oslo_concurrency] # ... lock_path = /var/lib/cinder/tmp
Populate the Block Storage database:
# su -s /bin/sh -c "cinder-manage db sync" cinder
Note
Ignore any deprecation messages in this output.
Configure Compute to use Block Storage
Edit the
/etc/nova/nova.conf
file and add the following to it:[cinder] os_region_name = RegionOne
Finalize installation
Restart the Compute API service:
# service nova-api restart
Restart the Block Storage services:
# service cinder-scheduler restart # service apache2 restart
