Equinix Metal NodeDriver

Initialize a NodeDriver for Equinix Metal using the API token and optionally the project (name or id).

If project name is specified we validate it lazily and populate self.project_id during the first access of self.projects variable

Returns:The newly created node. Return type:Node

create_volume(size, location, plan='storage_1', description='', ex_project_id=None, locked=False, billing_cycle=None, customdata='', snapshot_policies=None, **kwargs)

Create a new volume.

Parameters:

• size (int) – Size of volume in gigabytes (required)
• location (NodeLocation) – Which data center to create a volume in. If empty, undefined behavior will be selected. (optional)

Returns:

The newly created volume.

Return type:

create_volume_snapshot(volume, name='')

Create a new volume snapshot.

Parameters:volume (class:StorageVolume) – Volume to create a snapshot for Returns:The newly created volume snapshot. 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)

Delete an existing SSH key.

Parameters:key (KeyPair) – SSH key (required)

deploy_node(deploy, ssh_username='root', ssh_alternate_usernames=None, ssh_port=22, ssh_timeout=10, ssh_key=None, ssh_key_password=None, auth=None, timeout=300, max_tries=3, ssh_interface='public_ips', at_exit_func=None, wait_period=5, **create_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)
• 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)
