我目前是这样的，我是把我放网站的容器80和443端口映射到了我主机的3344端口和443端口，然后再把主机的80端口映射给3344，这样完成了一个网站重定向功能，用户访问我的域名就会直接跑3344端口。但是很奇怪的一点是，不知道为什么，我一完成80重定向3344这个动作，我的容器就无法联网了，如果没有做重定向就可以，可以调用阿里的短信功能

docker接口的映射：
[root@zsp ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9a83cf9e6c53 zspdisk7.0 "java -Djava.securit…" 2 days ago Up 2 days 0.0.0.0:443->443/tcp, 0.0.0.0:3344->80/tcp zspdisk7.0
acf3632502be mysql "docker-entrypoint.s…" 5 weeks ago Up 2 days 33060/tcp, 0.0.0.0:3310->3306/tcp mysql01
我在主机上使用的映射：
[root@zsp ~]# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3344
一旦使用了端口映射重定向域名到3344就会引发容器无法访问外网
