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.
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 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 --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 --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:

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() [...]
