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.

... services: proxy: ... lemmy: # image: dessalines/lemmy:dev # use this to build your local lemmy server image for development # run docker compose up --build build: context: ../ dockerfile: docker/Dockerfile # args: # RUST_RELEASE_MODE: release # this hostname is used in nginx reverse proxy and also for lemmy ui to connect to the backend, do not change hostname: lemmyJust copied this from the above URL. But just under
lemmy:there’s a few comments and the reference to the build section. You’ll want to remove those lines. and just have:lemmy: image: dessalines/lemmy:0.17.3-linux-arm64 ...You’ll need to do the same thing for
lemmy-ui, but it’s build section is already commented out but the default compose is using an incorrect tag for the Pi.See below:
... lemmy-ui: image: dessalines/lemmy-ui:0.17.1 # use this to build your local lemmy ui image for development # run docker compose up --build # assuming lemmy-ui is cloned besides lemmy directory # build: # context: ../../lemmy-ui # dockerfile: dev.dockerfile ...so for it, you just want to change it to:
lemmy-ui: image: dessalines/lemmy-ui:0.17.3-linux-arm64 ...Got it, thank you!
