Compute API¶

For details on how to use compute, see Using OpenStack Compute

The Compute Class¶

The compute high-level interface is available through the compute member of a Connection object. The compute member will only be added if the service is detected.

Server Operations¶

class openstack.compute.v2._proxy.Proxy(session=None, task_manager=None, *args, **kwargs)¶
