charm-neutron-api/README.md

Overview

This principle charm provides the Neutron API service which was previously provided by the nova-cloud-controller charm. When this charm is joined with the nova-cc charm the nova-cc charm will shutdown its api service, deregister it from neutron and inform the compute nodes of the new neutron url. This charm expects the following relations:

1. neutron-plugin-api relation with subordinate neutron plugin charms (such as neutron-openvswitch)
2. neutron-api relation with nova-cloud-controller
3. Database backend
4. amqp relation with message broker. If a single message broker is being used for the openstack deployemnt then it can relat to that. If a seperate neutron message broker is being used it should relate to that.
5. identity-service relation
6. ha relation with ha subordinate
