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.
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 -u root -p
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 |
| enabled | True |
| id | 8c2c7f1b9b5049ea9e63757b5533e6d2 |
| name | glance |
| type | image |
+-------------+----------------------------------+
Create the Image service API endpoints:
$ openstack endpoint create --region RegionOne \
image public http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 340be3625e9b4239a6415d034e98aace |

Note
Default configuration files vary by distribution. You might need
to add these sections and options rather than modifying existing
sections and options. Also, an ellipsis (...
) in the configuration
snippets indicates potential default configuration options that you
should retain.
Note
Starting with the Newton release, SUSE OpenStack packages are shipping
with the upstream default configuration files. For example
/etc/glance/glance-api.conf
or
/etc/glance/glance-registry.conf
, with customizations in
/etc/glance/glance-api.conf.d/
or
/etc/glance/glance-registry.conf.d/
. While the following
instructions modify the default configuration files, adding new files
in /etc/glance/glance-api.conf.d
or
/etc/glance/glance-registry.conf.d
achieves the same result.
Install the packages:
# zypper install openstack-glance \
openstack-glance-api openstack-glance-registry
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]
# ...
auth_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/
Edit the /etc/glance/glance-registry.conf
file and complete
the following actions:
Note
The Glance Registry Service and its APIs have been DEPRECATED in the Queens release and are subject to removal at the beginning of the ‘S’ development cycle, following the OpenStack standard deprecation policy.
For more information, see the Glance specification document Actually Deprecate the Glance Registry.
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]
# ...
auth_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.
Start the Image services and configure them to start when the system boots:
# systemctl enable openstack-glance-api.service \
openstack-glance-registry.service
# systemctl start openstack-glance-api.service \
openstack-glance-registry.service
