=============
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.
.. versionchanged:: 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``.
Depending on the Roles assigned to the authenticated OpenStack User, and upon
the configuration of the Bare Metal service, API responses may change. For
example, the default value of the "show_password" settings cause all API
responses to mask passwords within ``driver_info`` with the literal string
"\*\*\*\*\*\*".
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.
.. versionadded:: 1.2
Added ``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.
.. versionadded:: 1.5
Introduced the ``name`` field.
.. versionadded:: 1.7
Introduced the ``clean_step`` field.
.. versionchanged:: 1.11
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.
.. versionadded:: 1.12
Introduced support for the ``raid_config`` and ``target_raid_config`` fields.
.. versionadded:: 1.20
Introduced the ``network_interface`` field. If this field is not supplied
when creating the Node, the default value will be used.
.. versionadded:: 1.21
Introduced the ``resource_class`` field, which may be used to store a
resource designation for the proposed OpenStack Placement Engine. This field
has no effect within Ironic.
.. versionadded:: 1.31
Introduced the ``boot_interface``, ``deploy_interface``,
``management_interface``, ``power_interface``, ``inspect_interface``,
``console_interface``, ``vendor_interface`` and ``raid_interface`` fields. If
any of these fields are not supplied when creating the Node, their default
value will be used.
.. versionchanged:: 1.31
If the specified driver is a dynamic driver, then all the interfaces
(boot_interface, deploy_interface, etc.) will be set to the default interface
for that driver unless another enabled interface is specified in the creation
request.
.. versionadded:: 1.33
Introduced the ``storage_interface`` field. If this field is not supplied
when creating the Node, the default value will be used.
.. versionadded:: 1.38
Introduced the ``rescue_interface`` field. If this field is not supplied
when creating the Node, the default value will be used.

Response
--------
The response will contain the complete Node record, with the supplied data,
and any defaults added for non-specified fields. Most fields default to "null"
or "".
The list and example below are representative of the response as of API
microversion 1.38.

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.
.. versionadded:: 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.
.. versionadded:: 1.9
Added the ``provision_state`` Request parameter, allowing the list of
returned Nodes to be filtered by their current state.
.. versionadded:: 1.16
Added the ``driver`` Request parameter, allowing the list of returned Nodes
to be filtered by their driver name.
.. versionadded:: 1.21
Added the ``resource_class`` Request parameter, allowing the list of returned
Nodes to be filtered by this field.

List Nodes Detailed
===================
.. rest_method:: GET /v1/nodes/detail
Return a list of bare metal Nodes with complete details. Some filtering is
possible by passing in flags with the request.
This method is particularly useful to locate the Node associated to a given
Nova instance, eg. with a request to ``v1/nodes/detail?instance_uuid={NOVA INSTANCE UUID}``
.. versionadded:: 1.37
Introduced the ``traits`` field.
