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`.
