Each time, the refresh_token gets expired, the config needs to be generated.

I would like it know if you could add a kubeconfig file for the kubectl plugin https://github.com/int128/kubelogin, including a link for the installation manual.

Describe alternatives you've considered

Hello @jkroepke,

What are your TTL for both openid token & refresh token?
If your refresh token TTL is too low, you will have the same authentication issue with kubelogin (but instead, kubelogin open the browser for you).

About the additional configuration for kubelogin, you can override the existing html gotemplate with your own, with this you will be able to add your own documentation (which will include the link to download kubelogin if you want)

e.g. for dex expiration config --> https://dexidp.io/docs/id-tokens/#expiration-and-rotation-settings

I use 6h for idtoken and 48h (validForIfNotUsed) for refresh token on my configuration.
