list bridge addresses failed: no available network

docker 启动失败，journalctl -xe 查看发现报错"list bridge addresses failed: no available network"

定位是网络原因，采取最简单粗暴的方法：

• /var/lib/docker 清空

mv /var/lib/docker /var/lib/docker-bak

• 删除docker0和docker_gwbridge 网络

ifconfig docker0 down
brctl delbr docker0
ifconfig docker_gwbridge down
brctl delbr docker_gwbridge 

重启docker即可：

systemctl restart docker.service
