Issue in Docker build command

Thanks for quick response Ranjan.

As you suggested, I have changed the filename and rerun the build command.
Now I am getting different error in build command. Below are the details when I execute the build command.

Error is: repository name component must match "[a-z0-9] + (?: [ . _-][ a-z0-9] + ) * "
