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.

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.
Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

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                  |

| type        | image                            |
+-------------+----------------------------------+

Create the Image service API endpoints:

$ openstack endpoint create --region RegionOne \
  image public http://controller:9292

+--------------+----------------------------------+
| Field        | Value                            |

Install and configure components

Install the packages:
```
# apt install glance
```

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/

Populate the Image service database:
```
# su -s /bin/sh -c "glance-manage db_sync" glance
```
Note

Ignore any deprecation messages in this output.
