docker启动报错 iptables问题_failed to start daemon: error initializing network

##docker 启动时报错如下
root@DESKTOP-3TQ8K9B:~# systemctl start docker
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.

##可以通过如下命令查看docker的启动日志
root@DESKTOP-3TQ8K9B:~# sudo dockerd --debug

##报错信息
