在 docker 中访问 grunt serve

Question

我制作了 2 docker 个镜像（nginx、yeoman）并映射端口如下。

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 yeoman docker 来制作 grunt 服务器。

yeoman_docker$ yo  ..scafolding stuff  
yeoman_docker$ ls  
Gruntfile.js README.md  app  bower.json  bower_components  node_modules  package.json  test  
yeoman_docker$ grunt serve 
Running "serve" task


    Done, without errors.

保留此 SSH 以维护 grunt 服务。 Nginx 可以从本地访问 (127.0.0.1:8080) 但 grunt 无法访问 (127.0.0.1:9000)。在本地制作 grunt 服务器和 docker 有什么区别吗？我应该用它做什么？

grunt服务器好像不在本地

问题是您在 yeoman 容器中的连接服务器侦听容器内的本地主机：

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

在使用 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 以便连接服务器侦听 0.0.0.0.

在 docker 中访问 grunt serve

access grunt serve inside docker

gruntjs

yeoman

docker
