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.
[PENDING] Full documentation is available.
You'll also probably want to read OpenStack Compute Developer Guide API -- the first bit, at least -- to get an idea of the concepts. Rackspace is doing the cloud hosting thing a bit differently from Amazon, and if you get the concepts this library should make more sense.
This code a fork of Jacobian's python-cloudservers If you need API support for the Rackspace API solely or the BSD license, you should use that repository. python-client 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 Rackspace compatible API (including OpenStack).
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:

The server's certificate will not be verified against any certificate authorities. 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.
[PENDING] There's also a complete Python API.
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() [...]
