The interface was not collecting all keystone v3 information passed along the relation. This change adds the keystone v3 authentication settings. Avoid stestr failures due to lack of unit tests. Change-Id: If7dfd6ec0c6b4e88497c372a37c9be9844845e70 |

keystone-admin interface
Use this interface to use keystone credentials in your charm layers.
Purpose
By relating you charm layer (keystone-admin:identity-admin) with keystone service, keystone's API endpoint as well as username, password and region name will be shared.
How to use in your layers
The event handler for identity-admin.connected
is called when a relation
is established between your charm layer and keystone.
In case there are no unset shared data (ie: service_password), a new event
handler will be set: identity-admin.available
.
This object provides a method,
credentials()
returing a dict of:
{u'service_password': u'XXXXXXXX',
u'service_port': u'5000',
u'service_hostname': u'10.XX.XX.XXX',
u'service_username': u'admin',
u'service_tenant_name': u'Admin',
u'service_region': u'RegionOne'}
metadata.yaml
requires:
identity-admin:
interface: keystone-admin
layer.yaml,
includes: ['layer:basic', 'interface:keystone-admin']
charm layer example,
@when('identity-admin.available')
def setup_openstack_plugin(kst_data):
creds = kst_data.credentials()
if data_changed('identity-admin.config', creds):
settings = {'keystone_vip': creds['service_hostname'],
'keystone_port': creds['service_port'],
'username': creds['service_username'],
'password': creds['service_password'],
'tenant_name': creds['service_tenant_name'],
}
Example deployment
$ juju deploy your-awesome-charm
$ juju deploy keystone --config keystone-creds.yaml
$ juju deploy mysql
$ juju add-relation keystone mysql
$ juju add-relation your-awesome-charm keystone
where keystone-creds.yaml
has the necessary configuration settings for your
awesome charm to connect to keystone.
