查看k8s运行状态

systemctl status kubelet

 查看K8S运行日志

journalctl -xefu kubelet 

docker驱动与Kubelet的驱动程序不同导致

1、查看docker驱动

docker info|grep Driver

2、查看kubelet驱动

systemctl show --property=Environment kubelet |cat

 3、修改docker驱动，查看/etc/docker/daemon.json文件，没有的话，手动创建，添加以下内容

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

 4、重启docker

systemctl daemon-reload
systemctl restart docker

 5、重启kubelet

systemctl daemon-reload
systemctl restart kubelet
