Install and configure (Ubuntu)

This section describes how to install and configure the Image service, code-named glance, on the controller node. For simplicity, this configuration stores images on the local file system.

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
    • 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                             |

      | type        | image                            |
      +-------------+----------------------------------+
  4. Create the Image service API endpoints:

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