.. -*- rst -*- ============= Nodes (nodes) ============= List, Searching, Creating, Updating, and Deleting of bare metal Node resources are done through the ``/v1/nodes`` resource. There are also several sub-resources, which allow further actions to be performed on a bare metal Node. A Node is the canonical representation of a discretely allocatable server, capable of running an Operating System. Each Node must be associated with a ``driver``; this informs Ironic what protocol to use when managing the Node. Beginning with API microversion 1.6, a Node may be referenced both by its UUID and by a unique human-readable "name" in any request. Throughout this documentation, this is referred to as the ``node_ident``. Responses clearly indicate whether a given field is a ``uuid`` or a ``name``. Create Node =========== .. rest_method:: POST /v1/nodes Creates a new Node resource. This method requires that a ``driver`` be supplied in the request body. Most subresources of a Node (eg, ``properties``, ``driver_info``, etc) may be supplied when the Node is created, or the resource may be updated later. API microversion 1.2 introduced the new ``available`` state name, which replaced ``None`` as the status of an unprovisioned Node. All clients should be updated to use the new ``available`` state name. Nodes in the ``available`` state may have workloads provisioned on them; they are "available" for use. API microversion 1.11 changed the default initial state of newly-created Nodes from ``available`` to ``enroll``. This provides users a workflow to verify the manageability of a Node and perform necessary operational functions (eg, building a RAID array) before making the Node available for provisioning.

Most fields default to "null" or "". API microversion 1.5 introduced the ``name`` field. API microversion 1.7 introduced the ``clean_step`` field` API microversion 1.12 introduced support for the ``raid_config`` and ``target_raid_config`` fields. The list and example below are representative of the response as of API microversion 1.16. .. rest_parameters:: parameters.yaml - uuid: node_uuid - name: node_name - power_state: power_state - target_power_state: target_power_state - provision_state: provision_state - target_provision_state: target_provision_state - maintenance: maintenance - maintenance_reason: maintenance_reason - last_error: last_error - reservation: reservation - driver: driver_name - driver_info: driver_info - driver_internal_info: driver_internal_info - properties: n_properties - instance_info: instance_info - instance_uuid: instance_uuid - chassis_uuid: chassis_uuid - extra: extra - console_enabled: console_enabled - raid_config: raid_config - target_raid_config: target_raid_config - clean_step: clean_step - links: links - ports: n_ports - states: n_states **Example JSON representation of a Node:** .. literalinclude:: samples/node-create-response.json :language: javascript List Nodes ========== .. rest_method:: GET /v1/nodes Return a list of bare metal Nodes, with some useful information about each Node. Some filtering is possible by passing in flags with the request. By default, this query will return the name, uuid, instance uuid, power state, provision state, and maintenance setting for each Node. API microversion 1.8 added the ``fields`` Request parameter. When specified, this causes the content of the Response to include only the specified fields, rather than the default set. API microversion 1.9 added the ``provision_state`` Request parameter, allowing the list of returned Nodes to be filtered by their current state. API microversion 1.16 added the ``driver`` Request parameter, allowing the list of returned Nodes to be filtered by their driver name. Normal response codes: 200 ..
