Leader election in Kubernetes control plane - #HeptioProTip give a way how to find out leaders of Kubernetes control plane components kube-scheduler and kube-controller-manager. However it was based on a old version of kubernetes, and the mechanism is changed in later versions. Today I was asked how to find the leaders. Here is the new way to find. $ kubectl -n kube-system get lease NAME HOLDER AGE kube-apiserver-c4vwjftbvpc5os2vvzle4qg27a kube-apiserver-c4vwjftbvpc5os2vvzle4qg27a_b187371d-e48c-4216-8228-707a0ecf6100 2m57s kube-apiserver-dz2dqprdpsgnm756t5rnov7yka kube-apiserver-dz2dqprdpsgnm756t5rnov7yka_0b531f66-0c31-453c-9277-a6c1aa81da94 86s kube-apiserver-fyloo45sdenffw2ugwaz3likua kube-apiserver-fyloo45sdenffw2ugwaz3likua_3e322f9a-9724-4e3a-9fc6-a512e9424164 2m11s kube-controller-manager kind-control-plane_bec39b96-87c4-4bce-8775-2eeb4eb4c1e8 2m53s kube-scheduler kind-control-plane_db6f36d8-ceaa-40eb-b821-75f8ae829f22 2m53s $ kubectl -n kube-system get pods -l component=kube-controller-manager,tier=control-plane \ -o custom-columns=NAME:.
