我正在尝试使用 wercker 将 nginx 作为本地服务运行到我的开发管道，但我找不到正确的方法。

任何人都可以指出一个包含 nginx 作为本地服务的 wercker 多容器应用程序的工作示例吗？

我的项目是一个 Django 应用程序，开发管道目前工作正常，只有一个数据库注册为服务。我正在努力将网络服务器容器化，我希望将其作为Local Service。

基于本文档的“本地服务”部分：http: //devcenter.wercker.com/docs/services/advanced-services.html，我尝试了以下方法：

项目文件夹结构：

| (several other files) 
|-- .web-container 
|   |-- nginx-prd.conf 
|   `-- wercker.yml 
`-- wercker.yml       <------------ this is my 'main' wercker file

在主wercker 内部：

dev:
  services:
    - id: nginx
      url: file://.web-container/#dev
  steps:
    - script:
   (all the rest)

.web-container/wercker.yml 包含：

box: library/nginx
dev:
  steps:
    - script:
        name: Copy config files
        code: |
            cp ./nginx-prd.conf /etc/nginx/nginx.conf
     - internal/watch:
        code: tail -f /var/log/nginx/error.log;

当我运行时，我在发送命令之前$ wercker --verbose dev收到消息ERROR Session finished: [mkdir -p "/pipeline/output"]

当容器没有可用的 /bin/bash 时，我发现有关同一消息的问题报告，但事实并非如此。

我尝试了一些小的更改，例如定义入口点，定义不同的 cmd，但没有任何效果。

wercker dev 详细输出：
