This version required changing the previous access model for dashboard completely but it's a change for the better. Docs were updated. * New login/auth options that use apiserver auth proxying by default * Requires RBAC in `authorization_modes` * Only serves over https * No longer available at https://first_master:6443/ui until apiserver is updated with the https proxy URL: * Can access from https://first_master:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login you will be prompted for credentials * Or you can run 'kubectl proxy' from your local machine to access dashboard in your browser from: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/ * It is recommended to access dashboard from behind a gateway that enforces an authentication token, details and other access options here: https://github.com/kubernetes/dashboard/wiki/Accessing-Dashboard---1.7.X-and-above
