openstack.baremetal.v1.Node¶

The Node Class¶

The Node class inherits from Resource.

class openstack.baremetal.v1.node.Node(_synchronized=False, connection=None, **attrs)¶

The base resource

Parameters:	_synchronized (bool) – This is not intended to be used directly. See new() and existing(). connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of self._connection in Resource code should protect itself with a check for None.

create(session, *args, **kwargs)¶

Create a remote resource based on this instance.

The overridden version is capable of handling the populated provision_state field of one of three values: enroll, manageable or available. The default is currently available, since it’s the only state supported by all API versions.

Note that Bare Metal API 1.4 is required for manageable and 1.11 is required for enroll.

Parameters:	session (Adapter) – The session to use for making this request.
Returns:	This Resource instance.
Raises:	ValueError if the Node’s provision_state is not one of None, enroll, manageable or available.
Raises:	NotSupported if the provision_state cannot be reached with any API version supported by the server.

set_provision_state(session, target, config_drive=None, clean_steps=None, rescue_password=None, wait=False, timeout=None)¶

Run an action modifying this node’s provision state.

This call is asynchronous, it will return success as soon as the Bare Metal service acknowledges the request.

Parameters:	session (Adapter) – The session to use for making this request. target – Provisioning action, e.g. active, provide. See the Bare Metal service documentation for available actions. config_drive – Config drive to pass to the node, only valid for active` and ``rebuild targets. You can use functions from openstack.baremetal.configdrive to build it. clean_steps – Clean steps to execute, only valid for clean target. rescue_password – Password for the rescue operation, only valid for rescue target. wait – Whether to wait for the target state to be reached. timeout – Timeout (in seconds) to wait for the target state to be reached. If None, wait without timeout.
Returns:	This Node instance.
Raises:	ValueError if config_drive, clean_steps or rescue_password are provided with an invalid target.

wait_for_provision_state(session, expected_state, timeout=None, abort_on_failed_state=True)¶

Wait for the node to reach the expected state.

Parameters:

session (Adapter) – The session to use for making this request. expected_state – The expected provisioning state to reach. timeout – If wait is set to True, specifies how much (in seconds) to wait for the expected state to be reached. The value of None (the default) means no client-side timeout. abort_on_failed_state – If True (the default), abort waiting if the node reaches a failure state which does not match the expected one. Note that the failure state for enroll -> manageable transition is enroll again.

Returns:

This Node instance.

wait_for_reservation(session, timeout=None)¶

Wait for a lock on the node to be released.

Bare metal nodes in ironic have a reservation lock that is used to represent that a conductor has locked the node while performing some sort of action, such as changing configuration as a result of a machine state change.

This lock can occur during power syncronization, and prevents updates to objects attached to the node, such as ports.

Note that nothing prevents a conductor from acquiring the lock again after this call returns, so it should be treated as best effort.

Returns immediately if there is no reservation on the node.

Parameters:	session (Adapter) – The session to use for making this request. timeout – How much (in seconds) to wait for the lock to be released. The value of None (the default) means no timeout.
Returns:	This Node instance.

set_power_state(session, target)¶

Run an action modifying this node’s power state.

This call is asynchronous, it will return success as soon as the Bare Metal service acknowledges the request.

Parameters:	session (Adapter) – The session to use for making this request. target – Target power state, e.g. “rebooting”, “power on”. See the Bare Metal service documentation for available actions.

attach_vif(session, vif_id, retry_on_conflict=True)¶

Attach a VIF to the node.

The exact form of the VIF ID depends on the network interface used by the node. In the most common case it is a Network service port (NOT a Bare Metal port) ID. A VIF can only be attached to one node at a time.

Parameters:	session (Adapter) – The session to use for making this request. vif_id (string) – Backend-specific VIF ID. retry_on_conflict – Whether to retry HTTP CONFLICT errors. This can happen when either the VIF is already used on a node or the node is locked. Since the latter happens more often, the default value is True.
Returns:	None
Raises:	NotSupported if the server does not support the VIF API.

detach_vif(session, vif_id, ignore_missing=True)¶

Detach a VIF from the node.

The exact form of the VIF ID depends on the network interface used by the node. In the most common case it is a Network service port (NOT a Bare Metal port) ID.

Parameters:	session (Adapter) – The session to use for making this request. vif_id (string) – Backend-specific VIF ID. ignore_missing (bool) – When set to False ResourceNotFound will be raised when the VIF does not exist. Otherwise, False is returned.
Returns:	True if the VIF was detached, otherwise False.
Raises:	NotSupported if the server does not support the VIF API.

list_vifs(session)¶

List IDs of VIFs attached to the node.

The exact form of the VIF ID depends on the network interface used by the node. In the most common case it is a Network service port (NOT a Bare Metal port) ID.

Parameters:	session (Adapter) – The session to use for making this request.
Returns:	List of VIF IDs as strings.
Raises:	NotSupported if the server does not support the VIF API.

validate(session, required=('boot', 'deploy', 'power'))¶

Validate required information on a node.

Parameters:	session (Adapter) – The session to use for making this request. required – List of interfaces that are required to pass validation. The default value is the list of minimum required interfaces for provisioning.
Returns:	dict mapping interface names to ValidationResult objects.
Raises:	ValidationException if validation fails for a required interface.
