Install and configure (SUSE)¶

Prerequisites¶

Before you install and configure the Image service, you must create a database, service credentials, and API endpoints.

1. To create the database, complete these steps:

   • Use the database access client to connect to the database server as the root user:

     $ mysql -u root -p
     

   • Create the glance database:

     MariaDB [(none)]> CREATE DATABASE glance;
     

   • Grant proper access to the glance database:

     MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
       IDENTIFIED BY 'GLANCE_DBPASS';
     MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
       IDENTIFIED BY 'GLANCE_DBPASS';
     

     Replace GLANCE_DBPASS with a suitable password.

   • Exit the database access client.

2. Source the admin credentials to gain access to admin-only CLI commands:

   $ . admin-openrc
   

3. To create the service credentials, complete these steps:

   • Create the glance user:

     $ openstack user create --domain default --password-prompt glance
     
     User Password:
     Repeat User Password:
     +---------------------+----------------------------------+
     | Field               | Value                            |
     +---------------------+----------------------------------+
     | domain_id           | default                          |
     | enabled             | True                             |
     | id                  | 3f4e777c4062483ab8d9edd7dff829df |
     | name                | glance                           |
     | options             | {}                               |
     | password_expires_at | None                             |
     +---------------------+----------------------------------+
     

   • Add the admin role to the glance user and service project:

     $ openstack role add --project service --user glance admin
     

     Note

     This command provides no output.

   • Create the glance service entity:

     $ openstack service create --name glance \
       --description "OpenStack Image" image
     
     +-------------+----------------------------------+
     | Field       | Value                            |
     +-------------+----------------------------------+
     | description | OpenStack Image                  |
     | enabled     | True                             |
     | id          | 8c2c7f1b9b5049ea9e63757b5533e6d2 |
     | name        | glance                           |
     | type        | image                            |
     +-------------+----------------------------------+
     

4. Create the Image service API endpoints:

   $ openstack endpoint create --region RegionOne \
     image public http://controller:9292
   
   +--------------+----------------------------------+
   | Field        | Value                            |

Install and configure components¶

1. Install the packages:

   # zypper install openstack-glance \
     openstack-glance-api openstack-glance-registry
   

2. Edit the /etc/glance/glance-api.conf file and complete the following actions:

   • In the [database] section, configure database access:

     [database]
     # ...
     connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
     

     Replace GLANCE_DBPASS with the password you chose for the Image service database.

   • In the [keystone_authtoken] and [paste_deploy] sections, configure Identity service access:

     [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 = glance
     password = GLANCE_PASS
     
     [paste_deploy]
     # ...
     flavor = keystone
     

     Replace GLANCE_PASS with the password you chose for the glance user in the Identity service.

     Note

     Comment out or remove any other options in the [keystone_authtoken] section.

   • In the [glance_store] section, configure the local file system store and location of image files:

     [glance_store]
     # ...
     stores = file,http
     default_store = file
     filesystem_store_datadir = /var/lib/glance/images/
     

3. Edit the /etc/glance/glance-registry.conf file and complete the following actions:

   Note

   The Glance Registry Service and its APIs have been DEPRECATED in the Queens release and are subject to removal at the beginning of the ‘S’ development cycle, following the OpenStack standard deprecation policy.

   For more information, see the Glance specification document Actually Deprecate the Glance Registry.

   • In the [database] section, configure database access:

     [database]
     # ...
     connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
     

     Replace GLANCE_DBPASS with the password you chose for the Image service database.

   • In the [keystone_authtoken] and [paste_deploy] sections, configure Identity service access:

     [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 = glance
     password = GLANCE_PASS
     
     [paste_deploy]
     # ...
     flavor = keystone
     

     Replace GLANCE_PASS with the password you chose for the glance user in the Identity service.

     Note

     Comment out or remove any other options in the [keystone_authtoken] section.

Finalize installation¶

• Start the Image services and configure them to start when the system boots:

  # systemctl enable openstack-glance-api.service \
    openstack-glance-registry.service
  # systemctl start openstack-glance-api.service \
    openstack-glance-registry.service
