create_key_pair(name, public_key)[source]

Create a new SSH key.

Parameters:
  • name (str) – Key name (required)
  • public_key (str) – Valid public key string (required)
create_node(name, size, image, location, ex_project_id)[source]

Create a node.

Returns:The newly created node.
Return type:Node
create_volume(size, name, location=None, snapshot=None)

Create a new volume.

Parameters:
  • size (int) – Size of volume in gigabytes (required)
  • name (str) – Name of the volume to be created
  • location (NodeLocation) – Which data center to create a volume in. If empty, undefined behavior will be selected. (optional)
  • snapshot (VolumeSnapshot) – Snapshot from which to create the new volume. (optional)
Returns:

Return type:

StorageVolume

create_volume_snapshot(volume, name=None)

Creates a snapshot of the storage volume.

Parameters:
  • volume (VolumeSnapshot) – The StorageVolume to create a VolumeSnapshot from
  • name (str) – Name of created snapshot (optional)
Return type:

VolumeSnapshot

delete_image(node_image)

Deletes a node image from a provider.

Parameters:node_image (NodeImage) – Node image object.
Returns:True if delete_image was successful, False otherwise.
Return type:bool
delete_key_pair(key)[source]

Delete an existing SSH key.

Parameters:key (KeyPair) – SSH key (required)
deploy_node(**kwargs)

Create a new node, and start deployment.

In order to be able to SSH into a created node access credentials are required.

A user can pass either a NodeAuthPassword or NodeAuthSSHKey to the auth argument. If the create_node implementation supports that kind if credential (as declared in self.features['create_node']) then it is passed on to create_node. Otherwise it is not passed on to create_node and it is only used for authentication.

If the auth parameter is not supplied but the driver declares it supports generates_password then the password returned by create_node will be used to SSH into the server.

Finally, if the ssh_key_file is supplied that key will be used to SSH into the server.

This function may raise a DeploymentException, if a create_node call was successful, but there is a later error (like SSH failing or timing out). This exception includes a Node object which you may want to destroy if incomplete deployments are not desirable.

>>> from libcloud.compute.drivers.dummy import DummyNodeDriver
>>> from libcloud.compute.deployment import ScriptDeployment
>>> from libcloud.compute.deployment import MultiStepDeployment
>>> from libcloud.compute.base import NodeAuthSSHKey
>>> driver = DummyNodeDriver(0)
>>> key = NodeAuthSSHKey('...') # read from file
>>> script = ScriptDeployment("yum -y install emacs strace tcpdump")
>>> msd = MultiStepDeployment([key, script])
>>> def d():
...     try:
...         driver.deploy_node(deploy=msd)
...     except NotImplementedError:
...         print ("not implemented for dummy driver")
>>> d()
not implemented for dummy driver

Deploy node is typically not overridden in subclasses. The existing implementation should be able to handle most such.

Parameters:
  • deploy (Deployment) – Deployment to run once machine is online and available to SSH.
  • ssh_username (str) – Optional name of the account which is used when connecting to SSH server (default is root)
  • ssh_alternate_usernames (list) – Optional list of ssh usernames to try to connect with if using the default one fails
  • ssh_port (int) – Optional SSH server port (default is 22)
  • ssh_timeout (float) – Optional SSH connection timeout in seconds (default is 10)
  • auth (NodeAuthSSHKey or NodeAuthPassword) – Initial authentication information for the node (optional)
  • ssh_key (str or list of str) – A path (or paths) to an SSH private key with which to attempt to authenticate. (optional)
  • timeout (int) – How many seconds to wait before timing out. (default is 600)
  • max_tries (int) – How many times to retry if a deployment fails before giving up (default is 3)
  • ssh_interface (str) – The interface to wait for. Default is ‘public_ips’, other option is ‘private_ips’.
