Help with federation on my new instance (apollo.town)

submitted 1 year ago by tekeous to c/lemmy_support@lemmy.ml

22 comments fedilink hide all child comments

G'day, I just got Lemmy going on my site https://apollo.town and it doesn't appear to be federating. I ran through the Lemmy troubleshooting docs and I can return valid JSON from the site, but I can't look up anything on lemmy.ml from my site - although I can look up my site from lemmy.ml.

Caddy is my reverse proxy with the world's simplest config:

root@apollotown:~/lemmy# cat Caddyfile 
# apollo.town Lemmy instance
apollo.town {
	reverse_proxy :4040
}

Check the logs, if you see something about http error for lemmy.ml then the issue is the internal network.
Add a 3rd network just like the one for the proxy and add it to the lemmy container.
What happened to me was caused by this, the lemmy container couldn't connect to the internet so it wasn't able to find the other instances.

I think you might be on to something. I looked up myself(@tekeous@beehaw.org from apollo.town and got the following:

I'm not too familiar with docker networks - how would I add a third one?

[–] pe1uca@lemmy.pe1uca.dev 1 points 1 year ago* (last edited 1 year ago) (1 children)

So you want to have this:

networks:
  # only ports facing any connection from outside
  lemmyexternalproxy:
  lemmybridge:
  # communication between lemmy services
  lemmyinternal:
    driver: bridge
    internal: true

And in the container this.

lemmy:
    image: dessalines/lemmy:0.17.3
    hostname: lemmy
    networks:
      - lemmyinternal
      - lemmybridge
    restart: always

(leave the rest as is, you can name the new network however you want)

You're a bloody genius, thank you, that appears to have solved the problem.

Nice! This confirms it, I'll check tomorrow to share this in the repo to update the documentation.
