我一直无法在 Ubuntu v18.x 上找到使用 Python v3.x 运行 Robot Framework 的良好公共(public)镜像。一位同事构建了一个图像，我将其用作基础，但我的机器人脚本无法连接到该站点，并且我的轮子旋转太久了。是时候向社区寻求帮助了!
我有一个简单的机器人框架脚本(见下文)，它连接到一个站点(chrome headless)并验证标题。它可以在我的 Ubuntu 工作站上找到，但是当我在该工作站上运行 docker 容器时 - 它只是无法连接。最初，我认为这是一个管道问题，但事实并非如此。以下是我采取的步骤以及适用于我的工作站但不适用于容器的机器人代码:

我仍然无法让它直接与 ChromeDriver 一起工作，但是，我能够使用 selenium 网格让它工作:
https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar
我启动了一个集线器(在一个容器中)，然后直接在运行测试的容器上启动了一个节点，它工作了。我仍在努力构建运行节点的容器(虽然它不能作为单独的容器工作......我必须添加一些配置)。下面是使用远程 chrome 驱动程序的机器人框架测试套件:
