@derekbekoe, I made the fix. Let’s see how we can get the fix out sooner.

A workaround. Use ‘az acs list’ to get the ‘masterProfile’ ‘fqdn’ value and insert below for ‘master-fqdn’. The following two commands should perform the action to copy down the config file from the cluster master node which ‘az acs kubernetes get-credentials’ is failing to perform. I tested this locally and it’s working for me.

mkdir $HOME/.kube scp azureuser@<master-fqdn>:.kube/config $HOME/.kube/config
