Thank you for your contribution! This looks good. Would you tell me the message in your use case? I want to change the default message more helpful.

See also #193 (comment).

I would put something like <p>Kubernetes login successful. You can now close this page.</p>

I can update it in #308 if you like that wording

Thank you for your PR. I think the custom option is overkill and it would be happy for every users to make the default page more descriptive. I just created #312 and please let me know if you have ideas.

@sfxworks I'd like to confirm the purpose of #308 (comment). Do you need this feature to show a custom page after authentication?

I think it would be nice if user can set a URL to be redirected after authentication, like:

- name: oidc
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1
      args:
      - oidc-login
      - get-token
      - --oidc-issuer-url=https://accounts.google.com
      - --oidc-client-id=YOUR_CLIENT_ID
      - --auth-success-url=https://your-site.example.com/login-success.html
      command: kubectl

Correct! I would like to show users a success page. We are starting to work on a multi-tenant cluster so showing a login success page with a list of helpful resources (like example commands and links to support articles) would be nice for users new to kubectl.

Could you check the new version?
https://github.com/int128/kubelogin/releases/tag/v1.20.0

Now --open-url-after-authentication flag is available and the purpose of this feature is achieved. Please open a new feature request if needed.
