#cgroupdriver的驱动另一种方式
native.cgroupdriver=cgroupfs

修改存储位置

systemctl stop docker
cp -R -p /var/lib/docker/* /nasB/docker
vi /etc/docker/daemon.json
{
"data-root": "/nasB/docker",
}

#centos7.9
vi /usr/lib/systemd/system/docker.service
在 docker 启动时候 加载参数 --storage-opt dm.basesize=100G 用来调整默认容器的 rootfs大小；
在创建容器的时候使用参数--storage-opt size=30G来设置改容器的 rootfs 大小
