Juju Charm - Neutron API
Go to file
Alex Kavanagh b17bf9ed8d Change to the dhcp-agents-per-network setting such that it is always active
and not just when enable-l3ha is true.  This is to provide non-ha environments
with the option to have multiple dhcp agents (which are controlled directly by
neutron).  The default, is therefore, 1.

Overview

This principle charm provides the OpenStack Neutron API service which was previously provided by the nova-cloud-controller charm.

When this charm is related to the nova-cloud-controller charm the nova-cloud controller charm will shutdown its api service, de-register it from keystone and inform the compute nodes of the new neutron url.

Usage

To deploy (partial deployment only):

juju deploy neutron-api
juju deploy neutron-openvswitch

juju add-relation neutron-api mysql
juju add-relation neutron-api rabbitmq-server
juju add-relation neutron-api neutron-openvswitch
juju add-relation neutron-api nova-cloud-controller

This charm also supports scale out and high availability using the hacluster charm:

juju deploy hacluster neutron-hacluster
juju add-unit neutron-api
juju set neutron-api vip=<VIP FOR ACCESS>
juju add-relation neutron-hacluster neutron-api

Deploying from source

The minimum openstack-origin-git config required to deploy from source is:

openstack-origin-git: include-file://neutron-juno.yaml

neutron-juno.yaml
    repositories:
    - {name: requirements,
       repository: 'git://github.com/openstack/requirements',
       branch: stable/juno}
    - {name: neutron,
       repository: 'git://github.com/openstack/neutron',
       branch: stable/juno}

Note that there are only two 'name' values the charm knows about: 'requirements' and 'neutron'. These repositories must correspond to these 'name' values. Additionally, the requirements repository must be specified first and the neutron repository must be specified last. All other repostories are installed in the order in which they are specified.

The following is a full list of current tip repos (may not be up-to-date):

openstack-origin-git: include-file://neutron-master.yaml
