REST API Version History

1.91 (Dalmatian)

Removes special treatment of .json for API objects

  • /v1/nodes/test.json will now only mean node with the name “test.json”

  • /v1/nodes/test.json.json will mean a node with the name “test.json.json” and,

  • /v1/nodes/test will mean a node with the name “test”.

So /v1/nodes/test.json will no longer default to “test” and will HTTP 404 unless a node with the name “test” actually exists.

This also removes the backward compatibility with the guess_content_type_from_ext feature

1.90 (Caracal)

API supports ovn vtep switches as a valid schema for port.local_link_connection. Ovn vtep switches are represented as the following:

  "port_id": "exampleportid",
  "vtep-logical-switch": "examplelogicalswitch",
  "vtep-physical-switch": "examplephysicalswitch"

1.89 (Caracal)

Adds support to attaching or detaching images from a node’s virtual media using the /v1/nodes/{node_ident}/vmedia endpoint. A POST request containing device_type, image_url, and image_download_source will attach the requested image to the node’s virtual media. A later DELETE request to the same endpoint will detach it.

1.88 (Bobcat)

Added the name field to the port API. It should be unique when set, and can be used to identify a port resource.

1.87 (Bobcat)

Adds the service provision state verb to allow modifications via the “steps” interface to occur with a baremetal node. With this functionality comes a service_step field on the /v1/nodes based resources, which indicates the current step.

1.86 (Bobcat)

Adds a firmware_interface field to the /v1/nodes resources.

1.85 (Bobcat, 22.1)

This version adds a new provision state change verb called unhold to be utilized with the new provision_state values clean hold and deploy hold. The verb instructs Ironic to remove the node from it’s present hold and to resume it’s prior cleaning or deployment process.

1.84 (Bobcat, 22.1)

Add callback endpoint for in-band inspection /v1/continue_inspection. This endpoint is not designed to be used by regular users.

1.83 (Bobcat, 22.0)

This version adds a concept of child nodes through the use of a parent_node field which can be set on a node.

Under normal conditions, child nodes are not visible in the normal node list, as they are more for nested resources and not machines which can be freely used outside of an integrated context of the parent node. Think of a “child node” as a node with it’s own BMC embedded inside of an existing node.


  • Adds GET /v1/nodes/{node_ident}/children to return a list of node UUIDs which represent children, which can acted upon individually.

  • Adds GET /v1/nodes/?include_children=True to return a list of all parent nodes and children.

  • Adds GET /v1/nodes?parent_node={node_ident} to explicitly request a detailed list of nodes by parent relationship.

1.82 (Antelope, 21.4)

1.12 (Liberty, 4.2.0)

This API version adds the following abilities:

  • Get/set node.target_raid_config and to get node.raid_config.

  • Retrieve the logical disk properties for the driver.

1.11 (Liberty, 4.0.0, breaking change)

Newly registered nodes begin in the enroll provision state by default, instead of available. To get them to the available state, the manage action must first be run to verify basic hardware control. On success the node moves to manageable provision state. Then the provide action must be run. Automated cleaning of the node is done and the node is made available.

1.10 (Liberty, 4.0.0)

Logical node names support all RFC 3986 unreserved characters. Previously only valid fully qualified domain names could be used.

1.9 (Liberty, 4.0.0)

Add inspection process: introduce inspecting and inspectfail provision states, and inspect action that can be used when a node is in manageable provision state.

1.5 (Kilo)

Add logical node names that can be used to address a node in addition to the node UUID. Name is expected to be a valid fully qualified domain name in this version of API.

1.4 (Kilo)

Add manageable state and manage transition, which can be used to move a node to manageable state from available. The node cannot be deployed in manageable state. This change is mostly a preparation for future inspection work and introduction of enroll provision state.

1.3 (Kilo)

Add node driver_internal_info field.

1.2 (Kilo, breaking change)

Renamed NOSTATE (None in Python, null in JSON) node state to available. This is needed to reduce confusion around None state, especially when future additions to the state machine land.

1.1 (Kilo)

This was the initial version when API versioning was introduced. Includes the following changes from Kilo release cycle:

  • Add node maintenance_reason field and an API endpoint to set/unset the node maintenance mode.

  • Add sync and async support for vendor passthru methods.

  • Vendor passthru endpoints support different HTTP methods, not only POST.

  • Make vendor methods discoverable via the Ironic API.

  • Add logic to store the config drive passed by Nova.

This has been the minimum supported version since versioning was introduced.

1.0 (Juno)

This version denotes Juno API and was never explicitly supported, as API versioning was not implemented in Juno, and 1.1 became the minimum supported version in Kilo.
