有人可以指出我的 Dockerfile 有什么问题吗?另外，请告知如何将此文件转换为Alpine Linux

我需要在Docker容器中执行Selenium测试。我知道Selenium提供集线器和节点容器，但我必须编写自己的Dockerfile，它将构建一个容器，该容器将在没有网格配置的情况下执行测试。基本上，由于某种原因，我无法使用网格。我写了一个Dockerfile。它在构建阶段失败，并说无法清理项目。

我尝试在不添加任何用户的情况下打开火狐和 chrome，即尝试通过 root 用户执行，但它不起作用。然后我添加了一个用户，但它仍然不起作用。看起来权限已授予。请指出我哪里需要许可，哪一个是？下面是我的 Dockerfile。

它应该在无头模式下执行我的测试。

看起来您的automation用户没有Linux写入权限，因此他无法在Maven clean阶段删除target文件夹

更改此行：

COPY . /home/automation/myproject/

对此：

COPY --chown=automation . /home/automation/myproject/

我也没有在您的 Dockerfile 中看到任何真实或虚拟的显示配置，希望您将headless参数传递给浏览器初始化，否则您的测试将不起作用。

此外，请确保遵循并行测试 - 最佳实践，特别是：

  • 使用 ThreadLocal 来保存您的 WebDriver 实例和变量，这些变量不是全局的，也不是跨线程共享的
  • 避免使用静态方法和字段
  • 确保您的测试是独立、可重复和稳定的
可能是

您的自动化用户无权删除某些文件，我看到您使用自动化用户上下文来复制文件

COPY . /home/automation/myproject/

但是我在文件夹/主页/自动化/灭霸上看到了另一个错误....

Caused by: org.apache.maven.plugin.MojoExecutionException: Failed to clean project: Failed to delete /home/automation/thanos/target/generated-test-sources/test-annotations

您可以尝试更改用户的所有权或文件权限

chown -R $YOUR_USER /home/automation/
