@roycaihw Any plan to fix this? Thanks.

[pingsutw]

@jinchihe I got the same problem, did you solved it?

[jinchihe]

@pingsutw I pined to old kubernetes python sdk to work around that.

kindly ping @roycaihw , any updates for this? Thanks!

Thanks, it works for me

Add this to the api_client line ~215, solved the issue for now.
elif isinstance(obj, property):
return None

hello @roycaihw and all,

I found the problem still exists in 12.0.0, any plan to fix the problem? this is a block issue. Thanks.

[jinchihe]

Seems that's cuased by kubernetes client use openapi_types instead of swagger_types from 11.1?
https://github.com/kubernetes-client/python/commit/5cddbde0bfa2c8e10488978b0294f69c75fe0889#diff-a5cb6b73e3f53f068885d905bd488023

Need to update the generate openapi_types for the crd before calling k8s client.
Close the ticket. Thanks.

Sorry for the late response. Yes we've switch the code generator from swagger codegen to openapi generator, and the attribute was renamed from swagger_types to openapi_types. If you generated models for your custom resources, you need to regenerate them using openapi-generator. You could also use the dynamic client to access custom resources, which do not have this issue.

Yeah, I already did that. Thanks.

@roycaihw
I am simply using

client.CoreV1Api().create_namespaced_secret
client.CoreV1Api().create_namespaced_config_map

method and this method also has this issue in version 11.0.0 and 12.0.0. Note that these are not custom resources.
