创建覆盖层时出错，无法装载覆盖层:权限被拒绝

Question

我想将docker存储驱动器更改为overlay2以使用kubernetes

daemon.json:

{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
},
"storage-driver": "overlay2"
}

但是服务无法启动

journalcl-b-u docker.service:

level=error msg="failed to mount overlay: permission denied" storage-drive

sudo apt-get install docker-ce=5:19.03.5~3-0~ubuntu-xenial
