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 (
implements 100% of the OpenStack Nova API.
python-novaclient is licensed under the Apache License like the rest of OpenStack.
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
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
and the version of the API with
--version. Or set them as an environment
variables as well:
export OS_AUTH_URL=http://example.com:8774/v1.1/ export OS_COMPUTE_API_VERSION=1.1
If you are using Keystone, you need to set the NOVA_URL to the keystone endpoint:
Since Keystone can return multiple regions in the Service Catalog, you
can specify the one you want with
export OS_REGION_NAME). It defaults to the first in the list returned.
You'll find complete documentation on the shell by running

This option should be used with caution. --bypass-url <bypass-url> Use this API endpoint instead of the Service Catalog See "nova help COMMAND" for help on a specific command.
There's also a complete Python API, but it has not yet been documented.
Quick-start using keystone:
# use v2.0 auth with http://example.com:5000/v2.0/") >>> from novaclient.v1_1 import client >>> nt = client.Client(USER, PASS, TENANT, AUTH_URL, service_type="compute") >>> nt.flavors.list() [...] >>> nt.servers.list() [...] >>> nt.keypairs.list() [...]
