Authing no longer works with multiple args passed in as a list

[geoman3]

Recent change to auth'ing with ExecProvider broke my ability to auth.

This is what my k8's config looks like:

...
- name: <cluster-name>
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1
      args:
      - --region
      - <region>
      - eks
      - get-token
      - --cluster-name
      - <cluster-name>
      - --output
      - json
      - --role
      - <aws-role>
      command: aws
      env:
      - name: AWS_PROFILE
        value: <profile-name>
      interactiveMode: IfAvailable
      provideClusterInfo: false
...

I tested this with version 31 and 29

with version 31 I am seeing this being output in the terminal:

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help

aws: error: the following arguments are required: command

and then when I go to make a list pods call I get a 403 error as an unknown user

And on version 29 I do not see the above output and authentication works as desired.

I believe this is due to the following change: https://github.com/kubernetes-client/python/commit/2dfa782fb9bc575e2eef25b19b90a8284b491e03

which is causing all arguments following the first one to be dropped.

Let me know if you need any more information. I'm not too sure on the implications this would have for Windows users

• OS: MacOS 14.4.1
• Python version: 3.11.9

Thanks

I think PR #2289 broke it.

[obaranov]

Yeah, we hit the same issue while using the kubernetes.core Ansible collection. We had to revert back to the kubernetes==31.0.0.

https://github.com/kubernetes-client/python/pull/2338

does this PR fix the issue?

[jrwren]

I can confirm and reproduce this.

I can also confirm that going back to 31.0.0 works around it.

thanks, assigned the PR to you for review
