Docker -无法准备上下文:无法计算Dockerfile路径:GetFileAttributesEx中的符号链接

我今天刚刚下载了Windows 10 64位的Docker工具箱。我正在看教程。当我试图使用Dockerfile构建一个映像时，我收到以下错误。

步骤:

启动Docker快速入门终端。 Testdocker创建后。准备Dockerfile文档在“建立你自己的形象”网页链接运行以下命令

Docker build -t Docker -whale。

错误:$ docker build -t docker-whale。

unable to prepare context: unable to evaluate symlinks in Dockerfile path: GetFileAttributesEx C:\Users\Villanueva\Test\testdocker\Dockerfile:系统找不到指定的文件。

顺便说一句:我尝试了提到的几个选项@ https://github.com/docker/docker/issues/14339

docker info

当前回答

我把我的文件命名为dockerfile而不是dockerfile(大写)，一旦我改变了这个名字，它就开始处理我的“dockerfile”。

其他回答

错误消息具有误导性

这个问题实际上与符号链接无关。通常，问题只是Docker找不到描述构建的Dockerfile。

典型原因如下:

Dockerfile has wrong name. It must be called Dockerfile. If it is called, for instance, dockerfile, .Dockerfile, Dockerfile.txt, or other, it will not be found. Dockerfile is not in context. If you say docker build contextdir, the Dockerfile must be at contextdir/Dockerfile. If you have it in, say, ./Dockerfile instead, it will not be found. Dockerfile does not exist at all. Does it sound silly? Well, I got the above error message from my GitLab CI after I had written a nice Dockerfile, but I had forgotten to check it in. Silly? Sure. Unlikely? No.

要构建Dockerfile，请将自动化的内容保存在Dockerfile中。不是Dockerfile，因为在打开文件命令时:
