Inherited from NodeDriver:

Method __init__
Method reboot_node Reboot a node.
Method deploy_node Create a new node, and start deployment.
Method _wait_until_running Block until node is fully booted and has an IP address assigned.
Method _ssh_client_connect Try to connect to the remote SSH server. If a connection times out or is refused it is retried up to timeout number of seconds.
Method _run_deployment_script Run the deployment script on the provided node. At this point it is assumed that SSH connection has already been established.
Method _get_size_price Undocumented

Inherited from BaseDriver (via NodeDriver):

Method _ex_connection_class_kwargs Return extra connection keyword arguments which are passed to the Connection class constructor.
def __new__(cls, key, secret=None, api_version=DEFAULT_API_VERSION, **kwargs): (source)
Undocumented
def create_node(self, **kwargs): (source)

Returnslist of Node objects
def list_images(self, location=None): (source)
List images on a provider
ParameterslocationThe location at which to list images (type: NodeLocation)
Returnslist of NodeImage objects
def list_sizes(self, location=None): (source)
Return list of sizes on a provider.

See NodeDriver.list_sizes for more args.

ReturnsList of compute node sizes supported by the cloud provider. (type: list of OpenNebulaNodeSize)
def list_locations(self): (source)
List data centers for a provider
Returnslist of NodeLocation objects
def ex_list_networks(self, location=None): (source)
List virtual networks on a provider.
ParameterslocationLocation from which to request a list of virtual networks. (optional) (type: NodeLocation)
ReturnsList of virtual networks available to be connected to a compute node. (type: list of OpenNebulaNetwork)
def ex_node_action(self, node, action): (source)
Build action representation and instruct node to commit action.

Build action representation from the compute node ID, and the action which should be carried out on that compute node. Then instruct the node to carry out that action.

ParametersnodeCompute node instance. (type: Node)
actionAction to be carried out on the compute node. (type: str)
ReturnsFalse if an HTTP Bad Request is received, else, True is returned. (type: bool)
def _to_images(self, object): (source)
