解决docker创建容器或者开启时报错问题（driver failed programming external connectivity on endpoint nginx）

我输入的命令是

docker run -d --name nginx -p 80:80 nginx

但是报错了，报错信息如下

docker: Error response from daemon: driver failed programming external connectivity on endpoint nginx (ecc4fe2d2a9c4cf395adcf3329e8dcc59e429ef6ced134753baaec45ac80e1ab):  (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 80 -j DNAT --to-destination 172.17.0.3:80 ! -i docker0: iptables: No chain/target/match by that name.
 (exit status 1)).

解决方式是：

如果你之前关闭了防火墙，那么你需要重新启动一下docker

systemctl restart docker

然后在启动就没有问题了。
