Question

我制作了2个泊坞窗图像（nginx，yeoman）和映射端口，如下所示。

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

保持此SSH以维护grunt服务。 Nginx可从本地访问（127.0.0.1:8080）但grunt无法访问（127.0.0.1:9000）。在本地和docker中制作grunt服务器有什么区别吗？我该怎么办呢？

似乎grunt服务器不在本地。

问题是yeoman容器中的连接服务器侦听容器内的localhost：

Running "connect:livereload" (connect) task Started connect web server on http://localhost:9000

使用docker创建端口绑定时，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gruntfile.js，以便将服务器侦听连接到0.0.0.0。
