You can get it from endpoints resource. The endpoint should have an
annotation pointing to the leader.
$ kubectl get endpoints kube-controller-manager --namespace=kube-system -o
yaml
apiVersion: v1
kind: Endpoints
metadata:
annotations:
*control-plane.alpha.kubernetes.io/leader
<http://control-plane.alpha.kubernetes.io/leader>*: '{"holderIdentity":"
*kubernetes-master*
","leaseDurationSeconds":15,"acquireTime":"2017-02-14T14:05:57Z","renewTime":"2017-02-14T14:14:42Z","leaderTransitions":0}'
...
