Reviewing the Placement API, I noticed wrong OpenStack capitalization. Fix the docs and some strings as well. Change-Id: I14a2443687a0d517ece80e794e7ef0d4e165af6f

Traits
|
|
======
|
|
|
|
Traits are *qualitative* characteristics of resource providers.
|
|
The classic example for traits can be requesting disk from different
|
|
providers: a user may request 80GB of disk space for an instance
|
|
(quantitative), but may also expect that the disk be SSD instead of
|
|
spinning disk (qualitative). Traits provide a way to mark that a
|
|
storage provider is SSD or spinning.
|
|
|
|
.. note:: Traits API requests are availiable starting from version 1.6.
|
|
|
|
List traits
|
|
===========
|
|
|
|
Return a list of valid trait strings according to parameters specified.

Request

|
|
Several query parameters are available to filter the returned list of
|
|
traits. If multiple different parameters are provided, the results
|
|
of all filters are merged with a boolean `AND`.
|
|
|
|
.. rest_parameters:: parameters.yaml
|
|
|
|
- name: trait_name_query
|
|
- associated: trait_associated

.. rest_method:: GET /traits/{name}

Response

|
|
|

|
Update traits
|
|
=============
|
|
|
|
Insert a new custom trait. If traits already exists 204 will be returned.
|
|
|
|
There are two kinds of traits: the standard traits and the custom traits.
|
|
The standard traits are interoperable across different OpenStack cloud
|
|
deployments. The definition of standard traits comes from the `os-traits`
|
|
library. The standard traits are read-only in the placement API which means
|
|
that the user can't modify any standard traits through API.
|
|
The custom traits are used by admin users to manage the non-standard
|
|
qualitative information of resource providers.
|
|
|
|
.. rest_method:: PUT /traits/{name}
|
|
|
|
Normal Response Codes: 201, 204
|
|
|
|
Error response codes: badRequest(400)
|
|
|
|
* `400 BadRequest` if trait name is not prefixed with `CUSTOM_` prefix.

|
|
deleted.

|
ResourceProvider.
