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)
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

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.

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 Introspection 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 Introspection Rules
- actions rule actions, see Introspection Rules
- description (optional) human-readable description
- uuid (optional) rule UUID, autogenerated if missing
Response

- 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/<UUID> get one introspection rule by its <UUID>.

Response
- 200 - OK
- 404 - not found
Response body: JSON dictionary with introspection rule representation (see POST /v1/rules above).
DELETE /v1/rules/<UUID> delete one introspection rule by its <UUID>.

Response
- 204 - OK
- 404 - not found

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 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.

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

Version History¶

1.0 version of API at the moment of introducing versioning.
1.1 adds endpoint to retrieve stored introspection data.
