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-project-name``
params, but it's easier to just set them as environment variables::
export OS_USERNAME=<username>
export OS_PASSWORD=<password>
export OS_PROJECT_NAME=<project-name>
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
environment variables as well and set the OS_AUTH_URL to the keystone endpoint::
export OS_AUTH_URL=http://<url-to-openstack-keystone>:5000/v3/
export OS_COMPUTE_API_VERSION=2.1
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 keystoneauth1.identity import v3
>>> from keystoneauth1 import session
>>> from novaclient import client
>>> auth = v3.Password(auth_url='http://example.com:5000/v3',
... username='username',
... password='password',
... project_name='project-name',
... user_domain_id='default',
... project_domain_id='default')
>>> sess = session.Session(auth=auth)
>>> nova = client.Client("2.1", session=sess)
>>> nova.flavors.list()
[...]
>>> nova.servers.list()
[...]
>>> nova.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`.

Deprecating commands
====================
There are times when commands need to be deprecated due to rename or removal.
The process for command deprecation is:
1. Push up a change for review which deprecates the command(s).
- The change should print a deprecation warning to stderr each time a
deprecated command is used.
- That warning message should include a rough timeline for when the command
will be removed and what should be used instead, if anything.
- The description in the help text for the deprecated command should mark
that it is deprecated.
- The change should include a release note with the ``deprecations`` section
filled out.
- The deprecation cycle is typically the first client release *after* the
next *full* Nova server release so that there is at least six months of
deprecation.
2. Once the change is approved, have a member of the `nova-release`_ team
release a new version of python-novaclient.
.. _nova-release: https://review.openstack.org/#/admin/groups/147,members
3. Example: `<https://review.openstack.org/#/c/185141/>`_
This change was made while the Nova 12.0.0 Liberty release was in
development. The current version of python-novaclient at the time was
2.25.0. Once the change was merged, python-novaclient 2.26.0 was released.
Since there was less than six months before 12.0.0 would be released, the
deprecation cycle ran through the 13.0.0 Nova server release.
