=============
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``.
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.
If the specified driver is a dynamic driver (available from API microversion
1.31), 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.
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.

**Example Node creation request with a dynamic driver:**
.. literalinclude:: samples/node-create-request-dynamic.json
:language: javascript
**Example Node creation request with a classic driver:**
.. literalinclude:: samples/node-create-request-classic.json
:language: javascript
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 "".
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.
API microversion 1.20 introduced the ``network_interface`` field. If this field
is not supplied when creating the Node, the default value will be used.
API microversion 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.
API microversion 1.24 introduced the ``/nodes/{node_ident}/portgroups``
endpoint.
API microversion 1.31 introduced all of the ``*_interface`` fields
(boot_interface, deploy_interface, etc.), with the exception of the
network_interface field, which was introduced in API microversion 1.20. If this
field is not supplied when creating the Node, the default value will be used.
The list and example below are representative of the response as of API
microversion 1.31.

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.
API microversion 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}``
