list(associated=None, maintenance=None, marker=None, limit=None, detail=False, sort_key=None, sort_dir=None, fields=None, provision_state=None, driver=None, resource_class=None, chassis=None)

Retrieve a list of nodes.

Parameters:

• associated – Optional. Either a Boolean or a string representation of a Boolean that indicates whether to return a list of associated (True or “True”) or unassociated (False or “False”) nodes.
• maintenance – Optional. Either a Boolean or a string representation of a Boolean that indicates whether to return nodes in maintenance mode (True or “True”), or not in maintenance mode (False or “False”).
• provision_state – Optional. String value to get only nodes in that provision state.
• marker – Optional, the UUID of a node, eg the last node from a previous result set. Return the next result set.
• limit –

  The maximum number of results to return per

  request, if:

  1. limit > 0, the maximum number of nodes to return.
  2. limit == 0, return the entire list of nodes.
  3. limit param is NOT specified (None), the number of items returned respect the maximum imposed by the Ironic API (see Ironic’s api.max_limit option).
• detail – Optional, boolean whether to return detailed information about nodes.
• sort_key – Optional, field used for sorting.
• sort_dir – Optional, direction of sorting, either ‘asc’ (the default) or ‘desc’.
• fields – Optional, a list with a specified set of fields of the resource to be returned. Can not be used when ‘detail’ is set.
• driver – Optional. String value to get only nodes using that driver.
• resource_class – Optional. String value to get only nodes with the given resource class set.
• chassis – Optional, the UUID of a chassis. Used to get only nodes of this chassis.

Returns:

A list of nodes.

list_ports(node_id, marker=None, limit=None, sort_key=None, sort_dir=None, detail=False, fields=None)

List all the ports for a given node.

Parameters:

• node_id – Name or UUID of the node.
• marker – Optional, the UUID of a port, eg the last port from a previous result set. Return the next result set.
• limit –

  The maximum number of results to return per

  request, if:

  1. limit > 0, the maximum number of ports to return.
  2. limit == 0, return the entire list of ports.
  3. limit param is NOT specified (None), the number of items returned respect the maximum imposed by the Ironic API (see Ironic’s api.max_limit option).
• sort_key – Optional, field used for sorting.
• sort_dir – Optional, direction of sorting, either ‘asc’ (the default) or ‘desc’.
• detail – Optional, boolean whether to return detailed information about ports.
• fields – Optional, a list with a specified set of fields of the resource to be returned. Can not be used when ‘detail’ is set.

Returns:

A list of ports.

resource_class

alias of Node

set_boot_device(node_uuid, boot_device, persistent=False)

set_console_mode(node_uuid, enabled)

Set the console mode for the node.

Parameters:

• node_uuid – The UUID of the node.
• enabled – Either a Boolean or a string representation of a Boolean. True to enable the console; False to disable.

set_maintenance(node_id, state, maint_reason=None)

Set the maintenance mode for the node.

Parameters:

• node_id – The UUID of the node.
• state – the maintenance mode; either a Boolean or a string representation of a Boolean (eg, ‘true’, ‘on’, ‘false’, ‘off’). True to put the node in maintenance mode; False to take the node out of maintenance mode.
• maint_reason – Optional string. Reason for putting node into maintenance mode.

Raises:

InvalidAttribute if state is an invalid string (that doesn’t represent a Boolean).

set_power_state(node_id, state)

set_provision_state(node_uuid, state, configdrive=None, cleansteps=None)

Set the provision state for the node.

Parameters:

• node_uuid – The UUID or name of the node.
• state – The desired provision state. One of ‘active’, ‘deleted’, ‘rebuild’, ‘inspect’, ‘provide’, ‘manage’, ‘clean’, ‘abort’.
• configdrive – A gzipped, base64-encoded configuration drive string OR the path to the configuration drive file OR the path to a directory containing the config drive files. In case it’s a directory, a config drive will be generated from it. This is only valid when setting state to ‘active’.
• cleansteps – The clean steps as a list of clean-step dictionaries; each dictionary should have keys ‘interface’ and ‘step’, and optional key ‘args’. This must be specified (and is only valid) when setting provision-state to ‘clean’.

Raises:

InvalidAttribute if there was an error with the clean steps

Returns:

The status of the request

set_target_raid_config(node_ident, target_raid_config)

Sets target_raid_config for a node.

Parameters:

• node_ident – Node identifier
• target_raid_config – A dictionary with the target RAID configuration; may be empty.

Returns:

status of the request

states(node_uuid)

update(node_id, patch, http_method='PATCH')

validate(node_uuid)

vendor_passthru(node_id, method, args=None, http_method=None)

Issue requests for vendor-specific actions on a given node.

Parameters:

• node_id – The UUID of the node.
• method – Name of the vendor method.
• args – Optional. The arguments to be passed to the method.
• http_method – The HTTP method to use on the request. Defaults to POST.

wait_for_provision_state(node_ident, expected_state, timeout=0, poll_interval=2, poll_delay_function=None, fail_on_unexpected_state=True)

Helper function to wait for a node to reach a given state.

Polls Ironic API in a loop until node gets to a requested state.

Fails in the following cases: * Timeout (if provided) is reached * Node’s last_error gets set to a non-empty value * Unexpected stable state is reached and fail_on_unexpected_state is on * Error state is reached (if it’s not equal to expected_state)

Parameters:

• node_ident – node UUID or name
• expected_state – expected final provision state
• timeout – timeout in seconds, no timeout if 0
• poll_interval – interval in seconds between 2 poll
• poll_delay_function – function to use to wait between polls (defaults to time.sleep). Should take one argument - delay time in seconds. Any exceptions raised inside it will abort the wait.
• fail_on_unexpected_state – whether to fail if the nodes reaches a different stable state.

Raises:

StateTransitionFailed if node reached an error state

Raises:

StateTransitionTimeout on timeout
