解决Docker run 端口映射报错:iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8080 -j_docker iptables failed

运行:docker run -p 8080:8080 zstest

报错：

docker: Error response from daemon: driver failed programming external connectivity on endpoint agitated_perlman (5b968b19e9cb3ee66f8186079209771ac2c52b64579f8909d5e70337dede4e3e):  (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8080 -j DNAT --to-destination 172.17.0.3:8080 ! -i docker0: iptables: No chain/target/match by that name.

1、停止docker服务
  输入如下命令停止docker服务

systemctl stop docker

service docker stop

2、保存 iptables
  输入如下命令：

 iptables-save > /etc/sysconfig/iptables

保存之后的文件内容：

# Generated by iptables-save v1.4.21 on Sat Nov 24 13:53:13 2018
*nat

3、启动docker服务
  保存了iptables后,可以重新启动docker了。输入如下命令：

systemctl start docker 或者service docker start 

4、将docker设置为开机启动
  设置过这个就不需要再设置了

5、启动容器
  最后启动容器，发现不再报错了。

docker run -p 8080:8080 zstest
