Part of libcloud.compute.drivers.dummy View Source View In Hierarchy
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__ | Undocumented |
| 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 |
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() >>> sorted([node.name for node in driver.list_nodes()]) ['dummy-1', 'dummy-2', 'dummy-3']
Sets the node state to rebooting; in this dummy driver always returns True as if the reboot had been successful. >>> 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']
