How to run dockerfile in cmd

Question

I am using Windows 10 machine and new to docker technology.

I prepared the Dockerfile.txt file and kept inside the DockerFiles folder in local system.

and executed the below command.

docker build -t my-r-image .

But it is not able to read.

Can anyone please help?

The name is also correct.

Any suggestion will be highly appreciated.

Make sure your dockerfile has the same name as the one shown in your terminal, example:

failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount320670870/Dockerfile: no such file or directory

The dockerfile needs no extension, in Windows, you can create it with notepad++ and save it as "all types (.)"

You can try typing the full path of your dockerfile:

docker build -t X:X O:\Users\yyy\XX
