vsts 托管代理 docker 容器 (ubuntu) - 无法运行守夜人测试（在端口 4444 上连接到 127.0.0.1 时出错

Question

我正在尝试运行 Azure 管道中的硒测试运行出错 CICD 管道正在使用 VSTS 托管代理并构建一个 Ubuntu docker 容器。

我的测试任务是运行ning 在 Docker 容器映像构建之后并抛出以下错误。不知道我错过了什么。

测试工作在我的 windows 机器上找到。

如果需要任何进一步的信息，请告诉我

任何好的守夜人docker项目请把它扔在这里。

Answer 1

我自己找到了解决这个问题的方法。对于曾经尝试过相同的人，

请确保在 Docker Ubuntu

中安装了正确的二进制文件

package.json chrome devdependancy 正在将 .exe 二进制文件拉入 Docker ubuntu（看起来它是 [=32= 的问题] 驱动 npm 包）
确保 linux chrome 也安装在 Docker Ubuntu
首先尝试在本地 Docker 容器上设置项目，然后进入 docker 容器进行调试（基本上 bash 到 Docker 容器并尝试运行那里的测试）。如果测试运行正确，它们很可能应该运行在管道中正确

我打算很快写一篇端到端的设置博客。完成后我会在这里更新。
