Issues setting up instance with docker (lemmy.world)

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
Traceback (most recent call last):

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.

$ sudo docker-compose up -d

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.

Ok, that definitely helped. It now seems to run without errors...

Creating lemmy_pictrs_1   ... done
Creating lemmy_postgres_1 ... done
Creating lemmy_lemmy_1    ... done
Creating lemmy_lemmy-ui_1 ... done
Creating lemmy_proxy_1    ... done

But, then it just drops back to the command line. The docs say You can access the lemmy-ui at http://localhost:80, however, running a browser directly on the VM that lemmy is (supposedly) running on, and going to any of localhost:80, 127.0.0.1:80, the.machine.ip:80, all say unable to connect.

Seems to be running?

$ ps -ef | grep lemmy

Any tips on where to find logs, etc? I'm not even sure where it downloaded everything to, as it's not in the lemmy folder that the instructions had me create.

ETA: netstat -lp doesn't seem to show it listening on any ports.

Try add port to proxy and check http://localhost:82

  proxy:
    ports:
      - 82:80
      - 1236:1236
      - 8536:8536

Well, that resulted in something new.

404: FetchError: request to http://lemmy:8536/api/v3/site? failed, reason: connect ECONNREFUSED 172.20.0.4:8536

^^ Message in the browser window.

I has same issue, check if all ports are good i remember in some places there were UI on port 1234 and some 1236 in nginx.config, this config is a mess its esier write it from 0, also firewall can block your docker ip. But you are really close :D good luck
