Since I had a hard time, and ive seen a few people still having issues. None of the posts exactly helped with my setupI decided to post my current docker-compose lemmy conf and explain a few things.

Some steps are skipped such

Also the docker-compose in the docs wouldnt federate properly until i explicitly added ports to the compose.

FIRST STEPS

First off im running lemmy on oracle free tier arm instance with 4 cores 24 gb of ram. This vps is not accessible from the internet. ON another free box I run nginx Proxy Manager which connects to any vm on my home or other networks I want accessible.

I connect to the proxy box by using tailscale but any vpn should work

DOCKER INSTALL

So here is the compose file. the lemmy external host is the IP address of the proxy box. I used the tailscale ip . If you are not using an arm box remove the arm tag for the image.

now here is the lemmy.hconf that should be in same dierectory as compose file. Edit with the same db as in the compose.

Proxy setup

Make an entry for your server. i used the tailscale ip with the port in the compose 1236… Now you need to add this to the advanced tab.

This nginx.conf is default from the lemmy project used for the webserver and also needs to be in same directory as the compose.

You also need some custom locations in proxy manager. A new entry for each of these.

Location = /api

IP = internal IP of your server host

port = 8536 (lemmy port, not the lemmy-ui port)

Repeat the above for each of the others with locations as:

/pictrs

/feeds

/nodeinfo

With this setup only the box with nginx proxy manager is actually accessible while lemmy runs on a different one that is closed. The only thing different from the setup in the docs is ports listed for everything so they can communicate with nginx over tailscale.

    Thanks for sharing. The official installation documentation is a little out of date and I had issues too setting up the docker installation. Figured it out in the end but not after a lot of head scratching and testing.

      ya it was a bit frustrating, the docs had things missing or left out. seems like they updated it now but still a couple things i had to change.

    So, I’ve followed along with a arm vps. I have lemmy setup, but I’m missing the part on how to federate it. I went into the admin console and added sites to the “allowed instances” hit save, but I refresh the page and they are gone. What am I missing here?

      By putting things in the allow list I believe it blocks everything not in the list. I suggest doing a Blocklist instead. Not sure why it’s not saving g though id check the db. Also when I tried to block some instances the same thing happens too, could be a bug.

      Do you have tls set to try in your config? First thing to check.

      ** # Whether the site is available over TLS. Needs to be true for federation to work. tls_enabled: true**

    I was just playing with this yesterday trying to get the Docker image working on ARM and I went down a rabbit hole trying to build a new image for ARM, not realizing that one is already built/distributed 🤦

    Thanks for this!

      I didn’t notice either because the .16 version worked for me without a tag. When installing .17 I started getting errors and had to search around.
