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.
|
|
|
|
.. only:: obs or rdo or ubuntu
|
|
|
|
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 -u root -p
|
|
|
|
* Create the ``glance`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
CREATE DATABASE glance;
|
|
|
|
* Grant proper access to the ``glance`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
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.
|
|
|
|
#. Source the ``admin`` credentials to gain access to
|
|
admin-only CLI commands:
|
|
|
|
.. code-block:: console
|
|
|
|
$ . admin-openrc
|
|
|
|
#. 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:

|
|
| name | glance |
|
|
+-----------+----------------------------------+
|
|
|
|
* Add the ``admin`` role to the ``glance`` user and
|
|
``service`` project:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack role add --project service --user glance admin
|
|
|
|
.. 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 |
|
|
| enabled | True |

|
|
#. Create the Image service API endpoints:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack endpoint create --region RegionOne \
|
|
image public http://controller:9292
