我在 azure 管道中遇到了一个非常有趣的问题。问题是“构建上下文之外的禁止路径”。如果 Dockerfile 中有一条指向另一个目录的添加行，则映像构建失败并显示“禁止路径”消息。我该如何解决？

我最近尝试 Dockerize 一个 C# 项目，所以我在项目中添加了一个 docker 文件夹并创建了一个简单的 Dockerfile 以开始使用，如下所示：

如何解决“复制失败：构建上下文之外的禁止路径”？ 我想在 Dockerfiles 目录中使用 Dockerfile。

解决方法@H_197_1@ @H_197_30@

您可以尝试在 Docker 任务中添加 buildContext 参数。

buildContext：构建上下文的路径

这是您可以参考的 case。
