Hi Jay,
I want to create the Custom traits with the property value attached to it.
FOR Ex:
I want to have CUSTOM_xyz traits with "status": "true".
That's not a trait :) That's a status indicator.
Traits are simple string tags that represent a single-valued thing or
capability. A status is a multi-valued field.
When the CUSTOM_xyz traits is associated to a resource provider I should be
able to see the status value is true or not.
A trait is either associated with a resource provider or it isn't. When
you do a call to `GET /resource_providers/{rp_uuid}/traits` what is
returned is a list of the traits the resource provider with UUID
{rp_uuid} has associated with it.
I referred below link to create custom traits , not able to create.
https://specs.openstack.org/openstack/nova-specs/specs/pike/implemented/resource-provider-traits.html
PUT /resource_providers/{uuid}/traits
This API is to associate traits with specified resource provider. All the
associated traits will be replaced by the traits specified in the request body.
Nova-compute will report the compute node traits through this API.
The body of the request must match the following JSONSchema document:
{
"type": "object",
"properties": {
"traits": {
"type": "array",
"items": CUSTOM_TRAIT
},
"resource_provider_generation": {
"type": "integer"
}
},
'required': ['traits', 'resource_provider_generation'],
'additionalProperties': False
}
I suspect the issue you're having is that you need to create the custom
trait first and *then* associate that trait with one or more resource
providers.
To create the trait, do:
PUT /traits/CUSTOM_XYZ
and then associate it to a resource provider by doing:
PUT /resource_provider/{rp_uuid}/traits
{
"resource_provider_generation": 1,
"traits": [
"CUSTOM_XYZ"
]
}
BTW, a great place to see examples of both good and bad API usage is to
check out the Gabbit functional API tests for the placement API. Here is
the set of tests for the traits functionality:

Against the Pike placement API endpoint, make sure you send the following HTTP
header:
OpenStack-API-Version: placement 1.10

Thanks for reply Jay.
No Jay,
I have installed Pike. There also I face the same problem.
No, you haven't installed Pike (or at least not properly). Otherwise, the
max_version returned from the Pike placement API would be 1.10, not 1.4.

Hi,
We have implemented OpenStack Ocata and Pike releases, able to
consume Placement resource providers API, not able to consume resource class
APIs’.
I tried to run Triats API in Pike set up too. I am not able to run
any Traits API.
As per the Open Stack doc, the Placement API URL is a base URL for
Traits also. I am able to run Placement API as per the given doc,
not able to run/access the Traits APIs’ . Getting 404 (Not Found error).
The /traits REST endpoint is part of the Placement API, yes.
As mentioned in below link, the placement-manage os-traits
sync/command is not working, it says that command not found.
This means you have not installed (or updated) packages for Pike.

r
esource-provider-traits.html
Pike – Placement API version is 1.0 to 1.10
Ocata – Placement API version is 1.0 to 1.4 which support
We got 404 only, It seems there is a disconnect btw Placement and
Triats. Need to understand that are we missing any configuration.
You do not have Pike installed. You have Ocata installed. You need to upgrade
to Pike.
