docker image to docker file through vscode

I am unable to build docker file from docker image. (docker build -t thisismyfirstdocker .)

PS C:\Docker1\python-image> docker build -t thisismyfrstdocker .

I am trying to build dockerfile in vscode and expecting to build it but I got the error:

ERROR: failed to solve: the Dockerfile cannot be empty

Solution

  • There are some know issues that cause this:

    1. not capitalized dockerfile

    2. point to the build by -f flag:

      docker build -t thisismyfirstdocker -f somefile .

    3. Change COPY to ADD. (Here)
