Nextcloud behind Traefik2 - how?

Traefik Traefik v2
2

Hi @macmattias,

for a good diagnosis the logfile would be helpful.

This is my working configuration:

#(nextcloud docker-compose.yaml)
#[...]
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.nextcloud.entrypoints=web-secure"
      - "traefik.http.routers.nextcloud.rule=Host(`cloud.example.invalid`)"
      - "traefik.http.routers.nextcloud.tls=true"
      - "traefik.http.routers.nextcloud.tls.certresolver=tlschallenge"
      - "traefik.http.routers.nextcloud.middlewares=nextcloud-dav,secHeaders@file"
      - "traefik.http.middlewares.nextcloud-dav.replacepathregex.regex=^/.well-known/ca(l|rd)dav"
      - "traefik.http.middlewares.nextcloud-dav.replacepathregex.replacement=/remote.php/dav/"
      - "traefik.http.services.nextcloud.loadbalancer.server.port=80"
#[...]

I use this traefik-configuration: GitHub - wollomatic/traefik2-hardened: hardened rootless traefik2 deployment without mounting the docker socket into the traefik container

But it should also work with this simplified config: https://github.com/wollomatic/simple-traefik

I'd also recommend adding this to nextcloud´s config.php:

  'trusted_proxies' =>
  array (
    0 => 'xxx.xxx.xxx.xxx',
  ),

with xxx.xxx.xxx.xxx replaced with the IP of your traefik container. See Reverse proxy — Nextcloud latest Administration Manual latest documentation
