How to create secrets using Kubernetes Python client?
Almost everything that you have written is alright but pay attention to the message received from kube-apiserver:
HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"none in version "v1" cannot be handled as a Secret: no kind "none" is registered for version "v1"","reason":"BadRequest","code":400}
Especially no kind "none". Is it just typo or do you have something on your mind here?
You have list of kinds here https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#types-kinds
If you change kind to "Secret" then everything will be working fine.
