ETA: This is being done on a Raspberry Pi 4 running 64-bit Raspbian using an external SSD as storage.

I am following the instructions here: https://github.com/LemmyNet/lemmy-docs/blob/4249465e9960cad97245aa03b3ad4c758ff945c7/src/en/administration/install_docker.md

Please note that I have only used docker a few times in the past and have always failed so that could be a contributing factor.

My goal for the moment is just to have the instance on localhost so I can play around with it before deciding if running my own instance is something I have the time for.

Here are the steps I have taken so far and the result:

`WARNING: The Qa variable is not set. Defaulting to a blank string. WARNING: The k variable is not set. Defaulting to a blank string. ERROR: Couldn’t connect to Docker daemon at http+docker://localhost - is it running?

If it’s at a non-standard location, specify the URL with the DOCKER_HOST environment variable. `

I imagine I’m doing a lot of things wrong. I would be extremely appreciative for any help anybody can provide.

    Okay so here are the contents of the nginx.conf file:

    events {
        worker_connections 1024;
    }
    http {
    upstream lemmy {

        server "lemmy:8536";
    }
    upstream lemmy-ui {
        # this needs to map to the lemmy-ui docker service hostname
        server "lemmy-ui:1234";
    }
    
    server {
        # this is the port inside docker, not the public one yet
        listen 80;
