Why does Azure Kubernetes service prompt for credentials so frequently?

Hello support!

We are getting prompted to reauthenticate with Azure Kubernetes service every 15minutes and this is getting extremely annoying / frustrating our developers.

Here is an example when using kubectl: 50201-aks-frequent-login-prompts.jpg

Note:

Please advise what is causing this issue and how we can resolve it.

Thanks, Sean

    Yes, I can confirm that kubelogin has solved this problem for us.

    1. Download it from GitHub and place it into the same folder as Kubectl.
    2. Open a new terminal window and authenticate with your AKS cluster(s)
    3. Type "kubelogin convert-kubeconfig" and hit enter
    4. now you can use kubectl commands and your access token will be refreshed automatically (this even works after reboots, etc)

    Thanks!

    FYI - I have found this issue on Github which seems to describe the problem:

    -> https://github.com/Azure/AKS/issues/1669

    The workaround is to use the Kubelogin application, so I am trying that now to see if it helps.
