In Kubernetes v1. Apparently kubeadm v1. Configuring a cgroup driver This page explains how to configure the kubelet's cgroup driver to match the container runtime cgroup driver for kubeadm clusters. For the most part this was fine until I ran into one specific cluster that already had docker running with a cgroup driver of cgroupfs. For new clusters if you have not configured the cgroup driver explicitly you might get a failure in the kubelet on driver mismatch (kubeadm clusters should be using the systemd driver). 8 I had a hard time setting up a k8s cluster "the hard way" via kubeadm, even though it was just one node.
