failed to solve with frontend dockerfile.v0: failed to read dockerfile: error from sender: walk Dockerfile: The system cannot find the path specified.

Above is an example of the error I am getting and the command run. My Dockerfile is named "Dockerfile" as I have read on many answers but still no resolve. My Dockerfile is also within the directory I am in.

Answer 1

To build a docker image:

cd /path/where/docker_file/lives
docker build .

Above is same as:

docker build -f Dockerfile .

You need to specify Dockerfile name only if it is not default:

cd /path/where/docker_file/lives
docker build -f Dockerfile.modified .
