I’d like to self-host my own Lemmy instance. My environment is comprised of a Fedora VM on a separate VLAN running in Proxmox. That VM runs docker, and exposes all my services to Cloudflare using a treafik reverse proxy.

I have found some posts in my googlings of folks that were able to get Lemmy to work inside Traefik. I have tried their docker-compose files, and ultimately came up short.

My question, has anyone been able to get this working? If so, how?

    Maybe it’ll be easier if you share the exact issue you’re having.
    “came up short” doesn’t tell us anything on what to help you with.

    I’ve installed it with docker compose, but I use caddy in a dedicated debian VPS, so our setup is different but if your problem is with docker compose itslef maybe I could help you.

      This is valuable feedback. In retrospect I didn’t explain my problem at all. I’m really good at reading instructions, pretty poor at asking for help.

      I’m going to take another crack at this, after I read up on and learn all about Caddy. At first glance it looks like it takes away a lot of my pain points from Traefik.

    This is my ingressroute for lemmy:

    It seems to work correctly. Given that you’re not using kubernetes, you’ll need to do some translation work.

      Can you federate with kbin instances? The communities get stuck at subscribe pending for me.

      That’s the only thing not working and I assume I’m missing a proxy rule.

        • DomiEnglish
          1•1 year ago

          Figured it out. I also had to add the PUT, DELETE, PATCH and CONNECT rules, only POST doesn’t work for kbin apparently.

    It is pretty straight forward if you use the provided docker-compose file with the nginx internal proxy in it. Just add traefik as per usual to the internal port 8536 of the proxy container.

      This seems to be the easiest solution. Use the provided docker-compose file, then configure traefik to route requests to your lemmy domain to port 8536. How to do that depends on how you currently run traefik as there are multiple ways to configure it. Could be as simple as adding a label to the service named proxy in lemmy’s docker-compose file.

    I tried using Traefik in big corporation, 20+ different load balancer and reverse proxy (all with TLS termination) rules.

    Caddy not just worked, but also worked faster and was WAY simplier to setup (using Caddyfile and reverse_proxy directives) than Traefik.

      I’m reading about Caddy and playing around with it. It seems pretty straightforward. I’ll have to see if I can’t implement it.

        Here is the example docker-compose.yml:

        services:
  caddy:
    image: caddy
    container_name: caddy
    volumes:
      - ./caddy/data:/data
      - ./caddy/config:/config
      - ./caddy/Caddyfile:/etc/caddy/Caddyfile
    ports:
      - 80:80/tcp
      - 443:443/tcp
      - 443:443/udp
    restart: always

  lemmy:
    image: lemmy
    container_name: lemmy
    ...

        Before executing, create a new directory caddy i working directory, then create new file Caddyfile in it (lemmy is a container name):

        mydomain.com {
    reverse_proxy lemmy:<lemmy_container_http_port>
    encode zstd gzip
}

        Then fix your UDP Buffer size, so it’s compatible with QUIC: https://github.com/quic-go/quic-go/wiki/UDP-Buffer-Sizes

        And that’s it. tcp80, tcp443 and udp443 should be reachable from anywhere, as Caddy out of the box uses ACME to retrieve TLS certificates for your domain.

        Give it a try. Honestly Traefik is shit for a simple load balancer. It’s more suited for large enterprises and kubernetes services, but it also has numerous issues, such as basic auth performance issues, lack of headers customization as well as in overall somewhat difficult configuration. Caddy makes it straightforward & simple, which is perfect for simple users who love to self-host.
