I'm trying to spin up an instance on a local VM for my own testing so using the docker install.

I've reaching the point the instructions that say to run docker-compose up -d.

When I run that as my normal non-root user, I get a permission denied error.

$ docker-compose up -d

    sock.connect(self.unix_socket)

The first time I ran it with sudo, it downloaded a bunch of stuff (but to where I have no clue), and then gave the following error. Every subsequent run it skips the downloading (presumably because it already has all that), and goes straight to the error.

Building lemmy
unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /home/ME/docker: no such file or directory

It's clearly complaining about a missing file or folder in my home dir, but I have no idea what's supposed to be in that file/folder and it's not mentioned in the instructions. Suggestions?

ETA: Just to try something, I did a mkdir ~/docker and then touch ~/docker/Dockerfile, and now I get...

$ sudo docker-compose up -d
Building lemmy
Sending build context to Docker daemon  111.6MB
Error response from daemon: the Dockerfile (docker/Dockerfile) cannot be empty
ERROR: Service 'lemmy' failed to build : Build failed

Again. I have no idea what's supposed to be in that file. It's not mentioned in the instructions.
