Nextcloud on Raspberry Pi via docker compose - docker

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

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

Hope it helps.
