k8s 1.8 kubectl get nodes does not return controllers

I am performing test migrations from k8s 1.7 to 1.8. After I upgrade the workers and the controller managers I see that the output of kubectl get nodes only returns workers. Previously, on k8s 1.7 a kubectl get nodes would return the workers and the controller managers. I have tried this with the 1.7 and 1.8 version of kubectl.

I am not able to find anything in the 1.8 Changelog that states this output would change.

Is this expected output or is this a bug? I have asked this twice in the Slack channel and have not gotten a reply so I am asking here.

I had neglected to setup the kubeconfig flag for the kubelet wrapper in the controller setup. The controller was never registering to the api server. The --api-servers flag was deprecated in 1.8 and requires configuring the server in the kubeconfig file.
