Docker - curl: (56) Recv failure: Connection reset by peer解决方式

搭建docker中的mysql访问宿主机端口报错curl: (56) Recv failure: Connection reset by peer

解决方法很简单，重建docker0网桥，但出现错误原因不清楚

重建docker0网桥步骤：

# 停止docker
systemctl stop docker
# 安装bridge-utils
yum install -y bridge-utils 
# 关闭docker0网桥
ip link set dev docker0 down
# 删除docker0网桥
brctl delbr docker0
# 添加docker0网桥
brctl addbr docker0
# 添加网桥信息
ip addr add 172.17.10.1/16 dev docker0
# 启动docker0网桥
ip link set dev docker0 up
# 查看网桥是否正常
ip addr
# 启动docker
systemctl restart docker
