If you are using docker-compose.yml Just specify Dockerfile name

Wrong dockerfile: ./

Correct dockerfile: ./Dockerfile

If you have a dockerfile located somewhere in a file, first go to that file through commands i.e. cd ./onedrive/desktop/newfolder/docker/.

Then run command docker build . -t <your imagename : your image tag>

Here . gives you a default path where all the files in the local directory get tard and sent to the Docker daemon. -t gives you chance to give your image a name with a tag separated by :.

You then need to use the docker run command i.e. docker run <option/command> imagename.

It will give you a writeable container layer over the specified image, and then starts it using the specified command.

Use command docker ps to see if you have created a container with the image name you used. If not, there is probably a problem with how you are doing it or your pc environment.

P.S. You need to understand that dockerfile is a docker file, not a directory. So, if you see that your current directory is something/something/docker/dockerfile, you made a mistake. The dockerfile goes into docker folder by default.

Good luck

You can already see the problem at step 3. You created Dockerfile as a directory. It is a file. Delete the directory and make sure you have a file called Dockerfile in the directory where you run docker build. Make sure that Dockerfile is correctly edited.
