Lemmy Support

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:

• apt install docker-compose docker.io
• mkdir /lemmy
• cd /lemmy
• wget https://raw.githubusercontent.com/LemmyNet/lemmy/release/v0.17/docker/prod/docker-compose.yml
• wget https://raw.githubusercontent.com/LemmyNet/lemmy/release/v0.17/docker/prod/lemmy.hjson
• mkdir -p volumes/pictrs
• sudo chown -R 991:991 volumes/pictrs
• change db pswd in docker-compose.yml
• created nginx.conf (in root of lemmy folder) with config info on the above-linked page
• edited lemmy.hjson and changed admin username, admin pswd, site name, hostname (to "localhost," also tried "127.0.0.1"), set postgres pswd to db pswd I put into docker-compose.yml
• then i run docker-compose up -d and get the following message:

`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.
