Question

我有一个项目，我打算用wercker构建和发布多个Docker映像。每个项目的源代码都位于项目内各自的文件夹中。

作为一个简单的示例，我创建了一个repository，您可以在其中重现此问题。我使用了wercker's internal/docker-build。显然，在链接中有一个上下文属性context，但似乎没有作用：上下文似乎仍然是我项目的根。

我的文件夹结构：

根：
- flask-app
  - app.py
  - requirements.txt
  - Dockerfile
- wercker.yml

我的wercker.yml文件：

box:
id: python:2.7-slim
ports:
- "5000"

build:
  steps:
    - internal/docker-build:
        dockerfile: flask-app/Dockerfile
        context: flask-app
        image-name: flask-app

当我在项目根目录中运行wercker build --pipeline build时，输出：

--> No Docker host specified, checking: /var/run/docker.sock
--> Executing pipeline
--> Copying working directory to: /home/handris/Projects/wercker-context/.wercker/projects/wercker-context

Step 4/7 : COPY requirements.txt requirements.txt
--> Steps passed: 5.60s

它无法复制与Dockerfile相同文件夹中的我的requirements.txt。

我的巫师版本：

wercker version 1.0.1216 (Compiled at: 2018-05-01T13:14:48Z, Git commit: 426a99095ec0c95391620319833338afd1ccbc74)

我想念的是什么？如何使context属性与internal/docker-build一起使用？

编辑：我还尝试了在没有dockerfile属性的情况下运行构建，如下所示：

    - internal/docker-build:
      context: flask-app
      image-name: flask-app

在这种情况下，输出：

--> No Docker host specified, checking: /var/run/docker.sock
--> Executing pipeline
--> Copying working directory to: /home/handris/Projects/wercker-context/.wercker/projects/wercker-context
--> Copied working directory: 0.00s

--> Step failed: docker build Error response from daemon: Cannot locate specified Dockerfile: Dockerfile 0.28s
--> Pipeline failed: 3.40s
FATAL Step failed: docker build

我还尝试仅指定dockerfile属性，例如：

  steps:
    - internal/docker-build:
        dockerfile: flask-app/Dockerfile
        image-name: flask-app

在这种情况下，我的控制台输出与第一种情况相同。

Wercker的内部/ docker构建因上下文属性而失败
