Instantiating a driver

DigitalOcean driver supports two API versions - old API v1.0 and the new API v2.0. Since trunk (to be libcloud v0.18.0), the driver uses the correct API based on the initialization with the Client ID (key) and Access Token (secret) for v1.0 or the Personal Access Token (key) in v2.0 and will throw an exception if the api_version is set explicitly without the proper arguments.

Instantiating a driver using API v2.0

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

cls = get_driver(Provider.DIGITAL_OCEAN)

driver = cls('access token', api_version='v2')

Instantiating a driver using API v1.0

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

cls = get_driver(Provider.DIGITAL_OCEAN)
driver = cls('client id', 'api key', api_version='v1')

Creating a droplet using API v2.0

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

cls = get_driver(Provider.DIGITAL_OCEAN)

driver = cls('access token', api_version='v2')

options = {'backups': True,
           'private_networking': True,
           'ssh_keys': [123456, 123457]}

name = 'test.domain.tld'
size = driver.list_sizes()[0]
image = driver.list_images()[0]
location = driver.list_locations()[0]

node = driver.create_node(name, size, image, location,
                          ex_create_attr=options)

@inherits: NodeDriver.create_image

Parameters:
  • node (str) – Node to use as base for image
  • node – Name for image
Return type:

bool

create_key_pair(name, public_key='')[source]

Create a new SSH key.

Parameters:

create_node(name, size, image, location, ex_create_attr=None, ex_ssh_key_ids=None, ex_user_data=None)[source]

Create a node.

The ex_create_attr parameter can include the following dictionary key and value pairs:

  • backups: bool defaults to False
  • ipv6: bool defaults to False
  • private_networking: bool defaults to False
  • user_data: str for cloud-config data
  • ssh_keys: list of int key ids or str fingerprints

ex_create_attr[‘ssh_keys’] will override ex_ssh_key_ids assignment.

Parameters:

  • ex_ssh_key_ids (list of int key ids or str key fingerprints) – A list of ssh key ids which will be added to the server. (optional)
  • ex_user_data (str) – User data to be added to the node on create. (optional)
Returns:

The newly created node.

Return type:

Node

create_volume(size, name, location=None, snapshot=None)[source]

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)

delete_image(image)[source]

Delete an image for node.

@inherits: NodeDriver.delete_image

Parameters:image (NodeImage) – the image to be deleted
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.
