OS: Debian As kubernetes 1.23.1 recommend to use cgroup systemd, and docker 20.10.20 use cgroup cgroupfs. So, you have to change docker service file.

Step1: Stop docker service

systemctl stop docker

Step2: change on files /etc/systemd/system/multi-user.target.wants/docker.service and /usr/lib/systemd/system/docker.service

From :

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock


ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --exec-opt native.cgroupdriver=systemd

Step3: start docker service and kubelet

systemctl start docker

kubeadm init phase kubelet-start
