Docker: unable to prepare context: unable to evaluate symlinks in Dockerfile path: GetFileAttributesEx

Question

I just downloaded Docker Toolbox for Windows 10 64bit today. I\'m going through the tutorial. I\'m receving the following error when trying to build an image using a Docke

Answer 1

Be sure your DOCKERfile is in the ROOT of the application directory, I had mine in src which resulted in this error because Docker was not finding the path to DOCKERfile

Answer 2

I have got this error (in MacBook) though I used correct command to create image,

docker build -t testimg .

Later I found that path is the problem. Just navigate to the correct path that contains docker file. Just double check your current working directory .Nothing to panic!

Answer 3

Below command worked for me docker build -t docker-whale -f Dockerfile.txt .

Answer 4

Two ways to build a dockerfile:

You can decide not to specify the file name of which to build from and just build it specifying a path (doing it this way the file name must be Dockerfile with no extension appended, eg: docker build -t docker-whale:tag path/to/Dockerfile

or

You can specify a file with -f and it doesn't matter what extension (within reason .txt, .dockerfile, .Dockerfile etc..) you decide to use, eg docker build -t docker-whale:tag /path/to/file -f docker-whale.dockerfile.

Answer 5

I got this on Windows when the path I was working in was under a Junction directory. So my fix was to not work under that path.

Answer 6

I had created my DockerFile by VS2017 Docker Support tool and had the same error. After a while I realised I was not in the correct directory that contains the Dockerfile (~\source\repos\DockerWebApplication\). cd'ed to the correct file (~/source/repos/DockerWebApplication/DockerWebApplication) which was inside the project and successfully created the docker image.
