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.
The project is hosted on Launchpad, where bugs can be filed. The code is hosted on Github. Patches must be submitted using Gerrit, not Github pull requests.
python-novaclient is licensed under the Apache License like the rest of OpenStack.
Contents:
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/v1.1/ export OS_COMPUTE_API_VERSION=1.1
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:

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() [...]
