docker安装之后启动报错

● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
   Active: failed (Result: start-limit) since Sat 2021-03-06 14:25:32 CST; 5s ago

  Process: 2265 ExecStart=/usr/bin/dockerd (code=exited, status=1/FAILURE)
 Main PID: 2265 (code=exited, status=1/FAILURE)

修改添加以下信息，没有文件的话就创建一下

vim   /etc/docker/daemon.json

{
                       
            "storage-driver"
            : 
            "devicemapper"
}
