Solution

Append “–runtime-cgroups=/systemd/system.slice –kubelet-cgroups=/systemd/system.slice” to “KUBELET_CGROUP_ARGS” in /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

# vi /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
[Service]
Environment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf"
