django - 没有在带有 Docker 的 Django 应用程序上提交工作服

Question

我正在使用 Docker 开发一个 Django 项目。我已经配置了 Travis-Ci，我想向工作服提交测试覆盖率。但是，它没有按预期工作。任何帮助将不胜感激。

这是我得到的错误

要了解为什么没有提交覆盖率，您必须了解 docker 容器的运行方式。

创建容器是为了模仿一个单独的独立单元。这意味着在全局上下文中运行的命令与在容器上下文中运行的命令不同。

在您的情况下，您正在运行测试并在容器的上下文中生成覆盖率报告，然后尝试从全局上下文向工作服提交报告。

由于文件在容器中，coveralls 命令找不到报告，因此没有提交任何内容。

您可以引用此处提供的答案来解决此问题:
Coveralls: Error- No source for in my application using Docker container

或者查看 travis 提供的关于如何使用 docker 从 travis 提交工作服的文档:
