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 Dockerfile.

Steps:

• Launched Docker Quickstart terminal.
• testdocker after creating it.
• Prepare Dockerfile as documented in "Build your own image" web link
• ran below command

docker build -t docker-whale .

Error: $ docker build -t docker-whale .

unable to prepare context: unable to evaluate symlinks in Dockerfile path: GetFileAttributesEx C:\Users\Villanueva\Test\testdocker\Dockerfile: The system cannot find the file specified.

BTW: I tried several options mentioned @ https://github.com/docker/docker/issues/14339

Answer 1

while executing following command:

docker build -t docker-whale .

check that Dockerfile is present in your current working directory.
