:program:`openstack-compute` shell utilityThe
.. program:: openstack-compute
The :program:`openstack-compute` shell utility interacts with OpenStack Compute servers from the command line. It supports the entirety of the OpenStack Compute API (plus a few Rackspace-specific additions), including some commands not available from the Rackspace web console.
To try this out, you'll need a Rackspace Cloud account — or your own install of OpenStack Compute (also known as Nova). If you're using Rackspace you'll need to make sure to sign up for both Cloud Servers and Cloud Files -- Rackspace won't let you get an API key unless you've got a Cloud Files account, too. Once you've got an account, you'll find your API key in the management console under "Your Account".
You'll need to provide :program:`openstack-compute` with your Rackspace username and API key. You can do this with the :option:`--username` and :option:`--apikey` options, but it's easier to just set them as environment variables by setting two environment variables:
.. envvar:: OPENSTACK_COMPUTE_USERNAME Your Rackspace Cloud username.
.. envvar:: OPENSTACK_COMPUTE_API_KEY Your API key.
For example, in Bash you'd use:
export COPENSTACK_COMPUTE_USERNAME=yourname export COPENSTACK_COMPUTE_API_KEY=yadayadayada
From there, all shell commands take the form:
openstack-compute <command> [arguments...]
