HTTP API

By default ironic-discoverd listens on 0.0.0.0:5050, port can be changed in configuration. Protocol is JSON over HTTP.

The HTTP API consist of these endpoints:

Start Introspection

POST /v1/introspection/<UUID> initiate hardware introspection for node <UUID>. All power management configuration for this node needs to be done prior to calling the endpoint (except when Setting IPMI Credentials).

Requires X-Auth-Token header with Keystone token for authentication.

Optional parameters:

  • new_ipmi_password if set, ironic-discoverd will try to set IPMI password on the machine to this value. Power credentials validation will be skipped and manual power on will be required. See Setting IPMI credentials for details.
  • new_ipmi_username provides new IPMI user name in addition to password set by new_ipmi_password. Defaults to current ipmi_username in node driver_info field.

Response:

  • 202 - accepted discovery request
  • 400 - bad request
  • 401, 403 - missing or invalid authentication
  • 404 - node cannot be found

Get Introspection Status

GET /v1/introspection/<UUID> get hardware discovery status.

Requires X-Auth-Token header with Keystone token for authentication.

Response:

  • 200 - OK
  • 400 - bad request
  • 401, 403 - missing or invalid authentication
  • 404 - node cannot be found

Response body: JSON dictionary with keys:

  • finished (boolean) whether discovery is finished
  • error error string or null

Ramdisk Callback

POST /v1/continue internal endpoint for the discovery ramdisk to post back discovered data. Should not be used for anything other than implementing the ramdisk. Request body: JSON dictionary with at least these keys:

  • cpus number of CPU
  • cpu_arch architecture of the CPU
  • memory_mb RAM in MiB
  • local_gb hard drive size in GiB
  • interfaces dictionary filled with data from all NIC's, keys being interface names, values being dictionaries with keys:
    • mac MAC address
    • ip IP address
  • boot_interface optional MAC address of the NIC that the machine PXE booted from either in standard format 11:22:33:44:55:66 or in PXELinux BOOTIF format 01-11-22-33-44-55-66.
  • block_devices optional block devices information for root_device_hint plugin, dictionary with keys:
    • serials list of serial numbers of block devices.

Note

This list highly depends on enabled plugins, provided above are expected keys for the default set of plugins. See Plugins for details.

Response:

  • 200 - OK
  • 400 - bad request
  • 403 - node is not on introspection
  • 404 - node cannot be found or multiple nodes found

Response body: JSON dictionary. If Setting IPMI Credentials is requested, body will contain the following keys:

  • ipmi_setup_credentials boolean True
  • ipmi_username new IPMI user name
  • ipmi_password new IPMI password
