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                            |

   | url          | http://controller:9292           |

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]
     # ...
     auth_uri = http://controller:5000
     auth_url = http://controller:35357
     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:

   • 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]
     # ...
     auth_uri = http://controller:5000
     auth_url = http://controller:35357
     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
