This is a client for the OpenStack Nova API. There's a Python API (the
``novaclient`` module), and a command-line script (``nova``). Each
implements 100% of the OpenStack Nova API.
See the `OpenStack CLI guide`_ for information on how to use the ``nova``
command-line tool. You may also want to look at the
`OpenStack API documentation`_.

Command-line API
----------------
Installing this package gets you a shell command, ``nova``, that you
can use to interact with any OpenStack cloud.
You'll need to provide your OpenStack username and password. You can do this
with the ``--os-username``, ``--os-password`` and ``--os-tenant-name``
params, but it's easier to just set them as environment variables::
export OS_USERNAME=openstack
export OS_PASSWORD=yadayada
export OS_TENANT_NAME=myproject
You will also need to define the authentication url with ``--os-auth-url``
and the version of the API with ``--os-compute-api-version``. Or set them as
an environment variables as well::
export OS_AUTH_URL=http://example.com:8774/v2/
export OS_COMPUTE_API_VERSION=2
If you are using Keystone, you need to set the OS_AUTH_URL to the keystone
endpoint::
export OS_AUTH_URL=http://example.com:5000/v2.0/
Since Keystone can return multiple regions in the Service Catalog, you
can specify the one you want with ``--os-region-name`` (or
``export OS_REGION_NAME``). It defaults to the first in the list returned.
You'll find complete documentation on the shell by running
``nova help``
Python API
----------
There's also a complete Python API, with documentation linked below.
To use with keystone as the authentication system::
>>> from novaclient import client
>>> nt = client.Client(VERSION, USER, PASSWORD, TENANT, AUTH_URL)
>>> nt.flavors.list()
[...]
>>> nt.servers.list()
[...]
>>> nt.keypairs.list()
[...]
Testing
-------
There are multiple test targets that can be run to validate the code.
* tox -e pep8 - style guidelines enforcement
* tox -e py27 - traditional unit testing
* tox -e functional - live functional testing against an existing
openstack
Functional testing assumes the existence of a `clouds.yaml` file as supported
by `os-client-config` (http://docs.openstack.org/developer/os-client-config)
It assumes the existence of a cloud named `devstack` that behaves like a normal
devstack installation with a demo and an admin user/tenant - or clouds named
`functional_admin` and `functional_nonadmin`.
