- Please note that this module does not pick up typical proxy settings from the environment
(for example, HTTP_PROXY).

environment variable.

- This feature requires kubernetes>=19.15.0. When kubernetes library is less than
19.15.0, it fails even no_proxy set in correct.
- example value is "localhost,.local,.example.com,127.0.0.1,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16"

If your cluster has a different form of authentication (e.g. OAuth2 in OpenShift),
this option will not work as expected and you should look into the M(community.okd.k8s_auth)
module, as that might do what you need.

persist_config:
description:
- Whether or not to save the kube config refresh tokens. Can also be specified via
K8S_AUTH_PERSIST_CONFIG environment variable.
- When the k8s context is using a user credentials with refresh tokens (like oidc
or gke/gcloud auth), the token is refreshed by the k8s python client library but
not saved by default. So the old refresh token can expire and the next auth might
fail. Setting this flag to true will tell the k8s python client to save the new
refresh token to the kube config file.
- Default to false.
- Please note that the current version of the k8s python client library does not support
setting this flag to True yet.
- 'The fix for this k8s python library is here: https://github.com/kubernetes-client/python-base/pull/169'
