Lemmy, Traefik, & Docker (lemmy.world)

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?

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.
