问题：

[root@k8s-master02 ~]# systemctl status kubelet

查看kubelet运行日志

journalctl -xefu kubelet

docker驱动与kubelet驱动程序不同导致

查看docker驱动

[root@k8s-master02 ~]# docker info |grep Driver
 Storage Driver: overlay2
 Logging Driver: json-file
 Cgroup Driver: cgroupfs

修改docker驱动为systemd

"exec-opts": ["native.cgroupdriver=systemd"]

[root@k8s-master02 ~]# cat /etc/docker/daemon.json

  "registry-mirrors": ["https://v27k018o.mirror.aliyuncs.com"], "exec-opts": ["native.cgroupdriver=systemd"]

重启docker

systemctl daemon-reload
systemctl restart docker
systemctl restart kubelet
