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

openstack-origin-git: "{'neutron': {'repository': 'git://git.openstack.org/openstack/neutron.git', 'branch': 'stable/icehouse'}}"

If you specify a 'requirements' repository, it will be used to update the requirements.txt files of all other git repos that it applies to, before they are installed:

openstack-origin-git: "{'requirements': {'repository': 'git://git.openstack.org/openstack/requirements.git', 'branch': 'master'}, 'neutron': {'repository': 'git://git.openstack.org/openstack/neutron.git', 'branch': 'master'}}"

Note that there are only two key values the charm knows about for the outermost dictionary: 'neutron' and 'requirements'. These repositories must correspond to these keys. If the requirements repository is specified, it will be installed first. The neutron repository is always installed last. All other repostories will be installed in between.

NOTE(coreycb): The following is temporary to keep track of the full list of current tip repos (may not be up-to-date).

openstack-origin-git: "{'requirements': {'repository': 'git://git.openstack.org/openstack/requirements.git', 'branch': 'master'}, 'neutron-fwaas': {'repository': 'git://git.openstack.org/openstack/neutron-fwaas.git', 'branch': 'master'}, 'neutron-lbaas': {'repository: 'git://git.openstack.org/openstack/neutron-lbaas.git', 'branch': 'master'}, 'neutron-vpnaas': {'repository: 'git://git.openstack.org/openstack/neutron-vpnaas.git', 'branch': 'master'}, 'keystonemiddleware: {'repository': 'git://git.openstack.org/openstack/keystonemiddleware.git', 'branch: 'master'}, 'oslo-concurrency': {'repository': 'git://git.openstack.org/openstack/oslo.concurrency.git', 'branch: 'master'}, 'oslo-config': {'repository': 'git://git.openstack.org/openstack/oslo.config.git', 'branch: 'master'}, 'oslo-context': {'repository': 'git://git.openstack.org/openstack/oslo.context.git', 'branch: 'master'}, 'oslo-db': {'repository': 'git://git.openstack.org/openstack/oslo.db.git', 'branch: 'master'}, 'oslo-i18n': {'repository': 'git://git.openstack.org/openstack/oslo.i18n.git', 'branch: 'master'}, 'oslo-messaging': {'repository': 'git://git.openstack.org/openstack/oslo.messaging.git', 'branch: 'master'}, 'oslo-middleware: {'repository': 'git://git.openstack.org/openstack/oslo.middleware.git', 'branch': 'master'}, 'oslo-rootwrap': {'repository': 'git://git.openstack.org/openstack/oslo.rootwrap.git', 'branch: 'master'}, 'oslo-serialization': {'repository': 'git://git.openstack.org/openstack/oslo.serialization.git', 'branch: 'master'}, 'oslo-utils': {'repository': 'git://git.openstack.org/openstack/oslo.utils.git', 'branch: 'master'}, 'pbr': {'repository': 'git://git.openstack.org/openstack-dev/pbr.git', 'branch: 'master'}, 'python-keystoneclient': {'repository': 'git://git.openstack.org/openstack/python-keystoneclient.git', 'branch: 'master'}, 'python-neutronclient': {'repository': 'git://git.openstack.org/openstack/python-neutronclient.git', 'branch: 'master'}, 'python-novaclient': {'repository': 'git://git.openstack.org/openstack/python-novaclient.git', 'branch: 'master'}, 'stevedore': {'repository': 'git://git.openstack.org/openstack/stevedore.git', 'branch: 'master'}, 'neutron': {'repository': 'git://git.openstack.org/openstack/neutron.git', 'branch': 'master'}}"

Restrictions

This charm only support deployment with OpenStack Icehouse or better.
