DigitalOcean Compute Driver Documentation¶

DigitalOcean is an American cloud provider based in New York City with data centers in New York, Amsterdam, San Francisco, London, Singapore, Frankfurt, Toronto, and Bangalore.

Instantiating a driver¶

The DigitalOcean driver supports API v2.0, requiring a Personal Access Token to initialize as the key. The older API v1.0 reached end of life on November 9, 2015. Support for API v1.0 was removed in libcloud v1.2.2.

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")

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)

deploy_node(deploy: Deployment, ssh_username: str = 'root', ssh_alternate_usernames: Optional[List[str]] = None, ssh_port: int = 22, ssh_timeout: int = 10, ssh_key: Optional[T_Ssh_key] = None, ssh_key_password: Optional[str] = None, auth: T_Auth = None, timeout: int = 300, max_tries: int = 3, ssh_interface: str = 'public_ips', at_exit_func: Callable = None, wait_period: int = 5, **create_node_kwargs) → Node¶

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)
ssh_key_password (str) – Optional password used for encrypted keys.
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’.
at_exit_func (func) –
Optional atexit handler function which will be registered and called with created node if user cancels the deploy process (e.g. CTRL+C), after the node has been created, but before the deploy process has finished.

This method gets passed in two keyword arguments:
- driver -> node driver in question
- node -> created Node object
Keep in mind that this function will only be called in such scenario. In case the method finishes (this includes throwing an exception), at exit handler function won’t be called.
wait_period (int) – How many seconds to wait between each iteration while waiting for node to transition into running state and have IP assigned. (default is 5)
