在Docker中访问grunt服务
我做了两个docker图像（nginx，yeoman）和映射端口如下。
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3a71ee900cc0 webserver:0.1 "nginx" About an hour ago Up About an hour 443/tcp, 0.0.0.0:8080->80/tcp webserver af57b93ca326 silarsis/yeoman "/bin/bash" About an hour ago Up About an hour 0.0.0.0:9000->9000/tcp yeoman 并进入yeomandocker做出咕噜的服务器。

保持这个SSH来保持咕噜的服务。 Nginx可从本地访问（127.0.0.1:8080）但是grunt无法访问（127.0.0.1:9000）。 在本地和Docker中使用grunt服务器有什么区别吗？ 我该怎么办？
看起来，grunt服务器不在本地。
$ telnet 127.0.0.1 9000 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Connection closed by foreign host. $ netstat -ant Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 10.0.8.1:53 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp6 0 0 :::9000 :::* LISTEN tcp6 0 0 :::8080 :::* LISTEN tcp6 0 0 :::21 :::* LISTEN tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 127.0.0.1:9000 127.0.0.1:39682 TIME_WAIT
问题是yeoman容器中的连接服务器监听容器内的localhost：
Running "connect:livereload" (connect) task Started connect web server on http://localhost:9000
在使用docker创build端口绑定时，docker容器内的服务必须侦听主机0.0.0.0 ，而不是localhost 。 您需要更新您的gruntfile.js以便将服务器连接到0.0.0.0 。
