Concepts
|
|
========
|
|
|
|
In order to bring new features to users over time, the Ironic API
|
|
supports versioning. There are two kinds of versions in Ironic.
|
|
|
|
- ''major versions'', which have dedicated urls.
|
|
- ''microversions'', which can be requested through the use of the
|
|
``X-OpenStack-Ironic-API-Version`` header.
|
|
|
|
The Version APIs work differently from other APIs as they *do not* require authentication.
|
|
|
|
Beginning with the Kilo release, all API requests support the
|
|
``X-OpenStack-Ironic-API-Version`` header. This header SHOULD be supplied
|
|
with every request; in the absence of this header, each request is treated
|
|
as though coming from an older pre-Kilo client. This was done to preserve
|
|
backwards compatibility as we introduced new features in the server.
|
|
|
|
List API versions
|
|
=================
|
|
|
|
.. rest_method:: GET /
|
|
|
|
This fetches all the information about all known major API versions in the
|
|
deployment. Links to more specific information will be provided for each major
|
|
API version, as well as information about supported min and max microversions.
