Nextcloud on Raspberry Pi via docker compose

Question

I'm trying to run a Nextcloud instance on my Raspbery Pi 3B+ using a docker-compose file from this source: https://blog.ssdnodes.com/blog/installing-nextcloud-docker/

This works out of the box without any issues on a Ubuntu Server. I've replaced the following images to be compatible with the arm infrastructure of the Pi:

• jwilder/nginx-proxy:alpine with braingamer/nginx-proxy-arm or budry/jwilder-nginx-proxy-arm (I tried both)
• jrcs/letsencrypt-nginx-proxy-companion with budry/jrcs-letsencrypt-nginx-proxy-companion-arm
• mariadb with linuxserver/mariadb
• nextcloud:latest with linuxserver/nextcloud

Unfortunately this doesn't work on the Pi, the Pi returns first a 502 Bad Gateway, then after some time the error ERR_TOO_MANY_REDIRECTS.

What am I doing wrong?

Thanks

My docker-compose.yml:

The tutorial used a Nginx reverse proxy and Let’s Encrypt, for the latter you need a valid domain. If you look at your compose file for linuxserver/nextcloud under environment, it asks for a domain for VIRTUAL_HOST, LETSENCRYPT_HOST and LETSENCRYPT_EMAIL. It then tries to create a ssl certificate for the specified domain (nextcloud.domain.tld), which is not valid, so it doesn't work. This was the case for me, so I just removed the proxy and ssl from my compose file and nextcloud works now :)

Here is my current working compose file:

version: '3'

services:

  db:
    image: tobi312/rpi-mariadb:10.5
    container_name: nextcloud-mariadb
    networks:
      - nextcloud_network
    volumes:
      - db:/var/lib/mysql
      - /etc/localtime:/etc/localtime:ro
    environment:
      - MYSQL_ROOT_PASSWORD=very_secure_password
      - MYSQL_PASSWORD=very_secure_password
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
    restart: unless-stopped

  app:
    image: nextcloud:latest
    container_name: nextcloud-app
    networks:
      - nextcloud_network
    depends_on:
      - db
    volumes:
      - nextcloud:/var/www/html
      - ./app/config:/var/www/html/config
      - ./app/custom_apps:/var/www/html/custom_apps
      - ./app/data:/var/www/html/data
      - ./app/themes:/var/www/html/themes
      - /etc/localtime:/etc/localtime:ro
    restart: unless-stopped
    ports:
      - 80:80

volumes:
  nextcloud:
  db:

networks:
  nextcloud_network:
    driver: bridge

Hope it helps.
