.. _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/<Node ID>`` initiate hardware introspection for node
``<Node ID>``. 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.
Deprecated parameters (only available in API before version ``1.9``):
* ``new_ipmi_password``
* ``new_ipmi_username``
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/<Node ID>`` 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)
* ``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': true,
'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)
* ``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/<Node ID>/abort`` abort running introspection.
Requires X-Auth-Token header with Keystone token for authentication.
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/<Node ID>/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/<Node ID>/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.

* 401, 403 - missing or invalid authentication
* 404 - node not found for Node ID
* 409 - inspector locked node for processing

.. _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. If setting IPMI credentials (deprecated
feature) is requested, body will contain the following keys:
* ``ipmi_setup_credentials`` boolean ``True``
* ``ipmi_username`` new IPMI user name
* ``ipmi_password`` new IPMI password

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 avaliable.
* ``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
