I’ve been experiencing the same issue as the reporter, and I’ve traced the issue to the fact that my KUBECONFIG env var has a leading colon (:). Once I remove that leading colon, az aks get-credentials works as expected.

I don’t think my KUBECONFIG export statement has changed recently, and I recall doing a get-credentials within the last couple of months, so I’m wondering whether this is a regression in how KUBECONFIG is being parsed. kubectl has no problem with my KUBECONFIG env var and works as expected.

This line in my .zshrc is resulting in the leading colon due to $KUBECONFIG being undefined by default:

export KUBECONFIG=$KUBECONFIG:$HOME/.kube/config1:$HOME/.kube/config2

This results in:

> echo $KUBECONFIG
:/Users/myuser/.kube/config1:/Users/myuser/.kube/config2
