Install and configure

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.

obs or rdo or ubuntu

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:

      CREATE DATABASE glance;

    • Grant proper access to the glance database:

      GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
  IDENTIFIED BY 'GLANCE_DBPASS';
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 | e0353a670a9e496da891347c589539e9 |
| enabled   | True                             |
| id        | e38230eeff474607805b596c91fa15d9 |
| name      | glance                           |
+-----------+----------------------------------+

    • 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                            |
