[k8s]detected "cgroupfs" as the Docker cgroup driver. The recommended driver is "systemd"

安装k8s时报错

[root@master ~]# cat /etc/docker/daemon.json

],
"dns": ["114.114.114.114","8.8.4.4"],
"exec-opts": ["native.cgroupdriver=systemd"]            ### 新增这行
}
systemctl restart docker

检查

[root@master ~]# docker info | grep Cgroup
 Cgroup Driver: systemd
