Dummy node driver
This is a fake driver which appears to always create or destroy nodes successfully.
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> node=driver.create_node() >>> node.public_ip[0] '127.0.0.3' >>> node.name 'dummy-3'
If the credentials you give convert to an integer then the next node to be created will be one higher.
Each time you create a node you will get a different IP address.
>>> driver = DummyNodeDriver(22) >>> node=driver.create_node() >>> node.name 'dummy-23'
| Method | __init__ | |
| Method | get_uuid | Undocumented |
| Method | list_nodes | List the nodes known to a particular driver; There are two default nodes created at the beginning |
| Method | reboot_node | Sets the node state to rebooting; in this dummy driver always returns True as if the reboot had been successful. |
| Method | destroy_node | Sets the node state to terminated and removes it from the node list |
| Method | list_images | Returns a list of images as a cloud provider might have |
| Method | list_sizes | Returns a list of node sizes as a cloud provider might have |
| Method | list_locations | Returns a list of locations of nodes |
| Method | create_node | Creates a dummy node; the node id is equal to the number of nodes in the node list |
Inherited from NodeDriver:
| 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. |
| Parameters | key | API key or username to used (type: str) |
| secret | Secret password to be used (type: str) | |
| secure | Weither to use HTTPS or HTTP. Note: Some providers only support HTTPS, and it is on by default. (type: bool) | |
| host | Override hostname used for connections. (type: str) | |
| port | Override port used for connections. (type: int) | |
| api_version | Optional API version. Only used by drivers which support multiple API versions. (type: str) |
List the nodes known to a particular driver; There are two default nodes created at the beginning
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> node_list=driver.list_nodes() >>> sorted([node.name for node in node_list ]) ['dummy-1', 'dummy-2']
each item in the list returned is a node object from which you can carry out any node actions you wish
>>> node_list[0].reboot() True
As more nodes are added, list_nodes will return them
>>> node=driver.create_node() >>> node.size.id 's1' >>> node.image.id 'i2' >>> sorted([node.name for node in driver.list_nodes()]) ['dummy-1', 'dummy-2', 'dummy-3']
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> node=driver.create_node() >>> from libcloud.compute.types import NodeState >>> node.state == NodeState.RUNNING True >>> node.state == NodeState.REBOOTING False >>> driver.reboot_node(node) True >>> node.state == NodeState.REBOOTING True
Please note, dummy nodes never recover from the reboot.
Sets the node state to terminated and removes it from the node list
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> from libcloud.compute.types import NodeState >>> node = [node for node in driver.list_nodes() if node.name == 'dummy-1'][0] >>> node.state == NodeState.RUNNING True >>> driver.destroy_node(node) True >>> node.state == NodeState.RUNNING False >>> [node for node in driver.list_nodes() if node.name == 'dummy-1'] []
Returns a list of images as a cloud provider might have
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> sorted([image.name for image in driver.list_images()]) ['Slackware 4', 'Ubuntu 9.04', 'Ubuntu 9.10']
Returns a list of node sizes as a cloud provider might have
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> sorted([size.ram for size in driver.list_sizes()]) [128, 512, 4096, 8192]
Returns a list of locations of nodes
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> sorted([loc.name + " in " + loc.country for loc in driver.list_locations()]) ['Island Datacenter in FJ', 'London Loft in GB', "Paul's Room in US"]
Creates a dummy node; the node id is equal to the number of nodes in the node list
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> driver = DummyNodeDriver(0) >>> sorted([node.name for node in driver.list_nodes()]) ['dummy-1', 'dummy-2'] >>> nodeA = driver.create_node() >>> sorted([node.name for node in driver.list_nodes()]) ['dummy-1', 'dummy-2', 'dummy-3'] >>> driver.create_node().name 'dummy-4' >>> driver.destroy_node(nodeA) True >>> sorted([node.name for node in driver.list_nodes()]) ['dummy-1', 'dummy-2', 'dummy-4']
