Overview

This charm provides Nova Compute, the Openstack compute service. It's target platform is Ubuntu (preferably LTS) + Openstack.

Usage

The following interfaces are provided:

• cloud-compute - Used to relate (at least) with one or more of nova-cloud-controller, glance, ceph, cinder, mysql, ceilometer-agent, rabbitmq-server, neutron

• nrpe-external-master - Used to generate Nagios checks.

Database

Nova compute only requires database access if using nova-network. If using Neutron, no direct database access is required and the shared-db relation need not be added.

Networking

This charm support nova-network (legacy) and Neutron networking.

Storage

This charm supports a number of different storage backends depending on your hypervisor type and storage relations.

Deploying from source

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

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

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

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