Overview

Basic interface for sending Cinder subordinate backend configuration to principle Cinder charms.

Usage

Requires

This interface layer will set the following state:

• {relation_name}.connected The relation is established, but the charm may not have provided any backend information.

For example, the subordinate would handle the cinder-backend.connected state with something like:

@when('cinder-backend.connected')
def configure_cinder(cinder_principal):
    config = {'api-endpoint': '1.2.3.4',
              'admin-username': 'admin',
              'admin-password': 'openstack',
              'api-version': '1.0'}
    cinder_principle.configure_principal(
      backend_name='my_backend', configuration=config)
