Dockerfile in unusual place

Hi, if I follow the docker build instructions from within the deploy directory I will get error:

It is necessary to copy the Dockerfile to the root directory, which is where I would usually expect to find it. I would also recommend users to use the docker-compose

Thanks for the comment. You are correct that the Dockerfile is just for illustration, and not in the correct place. These docker workflows have not been used in production.

In truth, I have no actual experience with Docker (I find it difficult, and it has been on my to-do list for years), so I would welcome any recipes you develop, including those using docker-compose. Thanks!

I live in my own world of docker pain since I use an M1 Mac, and recall this gave me some issues. Will update here if I get back to it :)
