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:
.. code-block:: console
# mysql
.. end
* Create the ``glance`` database:
.. code-block:: console
MariaDB [(none)]> CREATE DATABASE glance;
.. end
* Grant proper access to the ``glance`` database:
.. code-block:: console
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';
.. end
Replace ``GLANCE_DBPASS`` with a suitable password.
* Exit the database access client.
#. Source the ``admin`` credentials to gain access to
admin-only CLI commands:
.. code-block:: console
$ . admin-openrc
.. end
#. To create the service credentials, complete these steps:
* Create the ``glance`` user:
.. code-block:: console
$ 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 |
+---------------------+----------------------------------+
.. end
* Add the ``admin`` role to the ``glance`` user and
``service`` project:
.. code-block:: console
$ openstack role add --project service --user glance admin
.. end
.. note::
This command provides no output.
* Create the ``glance`` service entity:
.. code-block:: console
$ openstack service create --name glance \
--description "OpenStack Image" image
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |

| id | 8c2c7f1b9b5049ea9e63757b5533e6d2 |
| name | glance |
| type | image |
+-------------+----------------------------------+
.. end
#. Create the Image service API endpoints:
.. code-block:: console
$ openstack endpoint create --region RegionOne \
image public http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |

| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
$ openstack endpoint create --region RegionOne \
image internal http://controller:9292

Install and configure components
--------------------------------
.. include:: note_configuration_vary_by_distribution.txt
#. Install the packages:
.. code-block:: console
# apt install glance
.. end
2. Edit the ``/etc/glance/glance-api.conf`` file and complete the
following actions:
* In the ``[database]`` section, configure database access:
.. path /etc/glance/glance.conf
.. code-block:: ini
[database]
# ...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
.. end
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:
.. path /etc/glance/glance.conf
.. code-block:: ini
[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
.. end
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:
.. path /etc/glance/glance.conf
.. code-block:: ini
[glance_store]
# ...
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
.. end
3. Populate the Image service database:
.. code-block:: console
# su -s /bin/sh -c "glance-manage db_sync" glance
.. end
.. note::
Ignore any deprecation messages in this output.
Finalize installation
---------------------
#. Restart the Image services:
.. code-block:: console
# service glance-api restart
.. end
