This enables the use of the OpenStack-API-Version header, in addition to the older X-OpenStack-Nova-API-Version header. If the client knows that it is in a version less than 2.27, it will not send the newer header. If the client knows that is in a version >= 2.27 if it gets a response that does not have the expected response header (the newer one) it will warn. If it is in an older version, it will warn about the other one missing. A server that is 2.27 or beyond will accept both headers and respond with both.

Python bindings to the OpenStack Nova API
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.
