HTTP API -------- .. _http_api: By default **ironic-inspector** listens on ``0.0.0.0:5050``, port can be changed in configuration. Protocol is JSON over HTTP. Start Introspection ~~~~~~~~~~~~~~~~~~~ ``POST /v1/introspection/`` initiate hardware introspection for node ````. All power management configuration for this node needs to be done prior to calling the endpoint. Requires X-Auth-Token header with Keystone token for authentication. Response: * 202 - accepted introspection request * 400 - bad request * 401, 403 - missing or invalid authentication * 404 - node cannot be found Get Introspection Status ~~~~~~~~~~~~~~~~~~~~~~~~ ``GET /v1/introspection/`` get hardware introspection 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 introspection is finished (``true`` on introspection completion or if it ends because of an error) * ``state`` state of the introspection * ``error`` error string or ``null``; ``Canceled by operator`` in case introspection was aborted * ``uuid`` node UUID * ``started_at`` a UTC ISO8601 timestamp * ``finished_at`` a UTC ISO8601 timestamp or ``null`` * ``links`` containing a self URL Get All Introspection Statuses ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``GET /v1/introspection`` get all hardware introspection statuses. Requires X-Auth-Token header with Keystone token for authentication. Returned status list is sorted by the ``started_at, uuid`` attribute pair, newer items first, and is paginated with these query string fields: * ``marker`` the UUID of the last node returned previously * ``limit`` default, max: ``CONF.api_max_limit`` Response: * 200 - OK * 400 - bad request * 401, 403 - missing or invalid authentication Response body: a JSON object containing a list of status objects:: { 'introspection': [ { 'finished': false, 'state': 'waiting', 'error': null, ... }, ... ] } Each status object contains these keys: * ``finished`` (boolean) whether introspection is finished (``true`` on introspection completion or if it ends because of an error) * ``state`` state of the introspection * ``error`` error string or ``null``; ``Canceled by operator`` in case introspection was aborted * ``uuid`` node UUID * ``started_at`` an UTC ISO8601 timestamp * ``finished_at`` an UTC ISO8601 timestamp or ``null`` Abort Running Introspection ~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``POST /v1/introspection//abort`` abort running introspection.

Response: * 202 - accepted * 400 - bad request * 401, 403 - missing or invalid authentication * 404 - node cannot be found * 409 - inspector has locked this node for processing Get Introspection Data ~~~~~~~~~~~~~~~~~~~~~~ ``GET /v1/introspection//data`` get stored data from successful introspection. Requires X-Auth-Token header with Keystone token for authentication. Response: * 200 - OK * 400 - bad request * 401, 403 - missing or invalid authentication * 404 - data cannot be found or data storage not configured Response body: JSON dictionary with introspection data .. note:: We do not provide any backward compatibility guarantees regarding the format and contents of the stored data. Notably, it depends on the ramdisk used and plugins enabled both in the ramdisk and in inspector itself. Reapply introspection on stored data ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``POST /v1/introspection//data/unprocessed`` to trigger introspection on stored unprocessed data. No data is allowed to be sent along with the request. Requires X-Auth-Token header with Keystone token for authentication. Requires enabling Swift store in processing section of the configuration file. Response: * 202 - accepted * 400 - bad request or store not configured * 401, 403 - missing or invalid authentication * 404 - node not found for Node ID * 409 - inspector locked node for processing Introspection Rules ~~~~~~~~~~~~~~~~~~~ See :ref:`rules ` for details. All these API endpoints require X-Auth-Token header with Keystone token for authentication. * ``POST /v1/rules`` create a new introspection rule. Request body: JSON dictionary with keys: * ``conditions`` rule conditions, see :ref:`rules ` * ``actions`` rule actions, see :ref:`rules ` * ``description`` (optional) human-readable description * ``uuid`` (optional) rule UUID, autogenerated if missing Response * 200 - OK for API version < 1.6 * 201 - OK for API version 1.6 and higher * 400 - bad request Response body: JSON dictionary with introspection rule representation (the same as above with UUID filled in). * ``GET /v1/rules`` list all introspection rules. Response * 200 - OK Response body: JSON dictionary with key ``rules`` - list of short rule representations. Short rule representation is a JSON dictionary with keys: * ``uuid`` rule UUID * ``description`` human-readable description * ``links`` list of HTTP links, use one with ``rel=self`` to get the full rule details * ``DELETE /v1/rules`` delete all introspection rules. Response * 204 - OK * ``GET /v1/rules/`` get one introspection rule by its ````. Response * 200 - OK * 404 - not found Response body: JSON dictionary with introspection rule representation (see ``POST /v1/rules`` above). * ``DELETE /v1/rules/`` delete one introspection rule by its ````. Response * 204 - OK * 404 - not found Ramdisk Callback ~~~~~~~~~~~~~~~~ .. _ramdisk_callback: ``POST /v1/continue`` internal endpoint for the 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: * ``inventory`` full `hardware inventory`_ from the ironic-python-agent with at least the following keys: * ``memory`` memory information containing at least key ``physical_mb`` - physical memory size as reported by dmidecode, * ``cpu`` CPU information containing at least keys ``count`` (CPU count) and ``architecture`` (CPU architecture, e.g. ``x86_64``), * ``bmc_address`` IP address of the node's BMC, * ``interfaces`` list of dictionaries with the following keys: * ``name`` interface name, * ``ipv4_address`` IPv4 address of the interface, * ``mac_address`` MAC (physical) address of the interface. * ``client_id`` InfiniBand Client-ID, for Ethernet is None. * ``disks`` list of disk block devices containing at least ``name`` and ``size`` (in bytes) keys. In case ``disks`` are not provided **ironic-inspector** assumes that this is a disk-less node. * ``root_disk`` default deployment root disk as calculated by the ironic-python-agent algorithm. .. note:: **ironic-inspector** default plugin ``root_disk_selection`` may change ``root_disk`` based on root device hints if node specify hints via properties ``root_device`` key. See `Specifying the disk for deployment root device hints`_ for more details. * ``boot_interface`` 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``. Strictly speaking, this key is optional, but some features will now work as expected, if it is not provided. Optionally the following keys might be provided: * ``error`` error happened during ramdisk run, interpreted by ``ramdisk_error`` plugin. * ``logs`` base64-encoded logs from the ramdisk. .. note:: This list highly depends on enabled plugins, provided above are expected keys for the default set of plugins. See :ref:`plugins ` for details. .. note:: This endpoint is not expected to be versioned, though versioning will work on it. 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 with ``uuid`` key. .. _hardware inventory: https://docs.openstack.org/ironic-python-agent/latest/admin/how_it_works.html#hardware-inventory .. _Specifying the disk for deployment root device hints: http://docs.openstack.org/project-install-guide/baremetal/draft/advanced.html#specifying-the-disk-for-deployment-root-device-hints Error Response ~~~~~~~~~~~~~~ If an error happens during request processing, **Ironic Inspector** returns a response with an appropriate HTTP code set, e.g. 400 for bad request or 404 when something was not found (usually node in cache or node in ironic). The following JSON body is returned:: { "error": { "message": "Full error message" } } This body may be extended in the future to include details that are more error specific. API Versioning ~~~~~~~~~~~~~~ The API supports optional API versioning. You can query for minimum and maximum API version supported by the server. You can also declare required API version in your requests, so that the server rejects request of unsupported version. .. note:: Versioning was introduced in **Ironic Inspector 2.1.0**. All versions must be supplied as string in form of ``X.Y``, where ``X`` is a major version and is always ``1`` for now, ``Y`` is a minor version. * If ``X-OpenStack-Ironic-Inspector-API-Version`` header is sent with request, the server will check if it supports this version. HTTP error 406 will be returned for unsupported API version. * All HTTP responses contain ``X-OpenStack-Ironic-Inspector-API-Minimum-Version`` and ``X-OpenStack-Ironic-Inspector-API-Maximum-Version`` headers with minimum and maximum API versions supported by the server. .. note:: Maximum is server API version used by default. API Discovery ~~~~~~~~~~~~~ The API supports API discovery. You can query different parts of the API to discover what other endpoints are available. * ``GET /`` List API Versions Response: * 200 - OK Response body: JSON dictionary containing a list of ``versions``, each version contains: * ``status`` Either CURRENT or SUPPORTED * ``id`` The version identifier * ``links`` A list of links to this version endpoint containing: * ``href`` The URL * ``rel`` The relationship between the version and the href * ``GET /v1`` List API v1 resources Response: * 200 - OK Response body: JSON dictionary containing a list of ``resources``, each resource contains: * ``name`` The name of this resources * ``links`` A list of link to this resource containing: * ``href`` The URL * ``rel`` The relationship between the resource and the href Version History ^^^^^^^^^^^^^^^ * **1.0** version of API at the moment of introducing versioning. * **1.1** adds endpoint to retrieve stored introspection data. * **1.2** endpoints for manipulating introspection rules. * **1.3** endpoint for canceling running introspection * **1.4** endpoint for reapplying the introspection over stored data. * **1.5** support for Ironic node names. * **1.6** endpoint for rules creating returns 201 instead of 200 on success. * **1.7** UUID, started_at, finished_at in the introspection status API. * **1.8** support for listing all introspection statuses. * **1.9** de-activate setting IPMI credentials, if IPMI credentials are requested, API gets HTTP 400 response. * **1.10** adds node state to the GET /v1/introspection/ and GET /v1/introspection API response data. * **1.11** adds invert&multiple fields into rules response data * **1.12** this version indicates that support for setting IPMI credentials was completely removed from API (all versions).
