Can't get nextcloud to use my SMB share as a data folder

Hi all

I've tried to install nextcloud with serveral Docker copose files I found here and on the internet. I managed to install it without any problems, and even setup remote access via cloudflared tunnel using the attached compose file.
My goal is to turn part of my SMB share to a synced cloud storage, so I can access and work on some of my files remotely and have everything synced in real time.
The only problem I have is that no matter what I do, it totally disregards my path settings and installs it into the /var/www/html on the boot drive.
I know this can be done using syncthing but unfortunatly, so far I haven't been able to get it to work and, and I've finished runnig tests and installed my work machine as I don't really have time to continue tinkering with it.
This is my Docker Compose file.

version: "2"
services: 
  app: 
    depends_on: 
      - db
    environment: 
      - MYSQL_PASSWORD=MyPass
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db
    image: nextcloud
    links: 
      - db
    ports: 
      - 8080:80
    restart: always
    volumes: 
      - /home/docker/nextcloud/nextcloud:/nextcloud
      - /home/docker/nextcloud/apps:/custom_apps
      - /home/docker/nextcloud/config:/config
      - /srv/mergerfs/Public/Cloud:/data
        db: 
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    environment: 
      - MYSQL_ROOT_PASSWORD=MyPass
      - MYSQL_PASSWORD=My Pass
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
    image: mariadb:10.5
    restart: always
    volumes: 
      - /home/docker/nextcloud/db:/mysql
    
  redis:
    command: redis-server --requirepass MyPass
    environment:
      - REDIS_HOST=redis
      - REDIS_HOST_PASSWORD=MyPass
    image: redis:latest
    restart: always

Thank you in advance

You can use the remote storage app in Nextcloud to get access to your smb shares via Nextcloud.

Mapping a smb share to /data does not work due to incompatible permissions. Has been tried before. You can search the forum.

Thank you for your reply.
Another question if I may.
I have a large ammount of data that is currently on my desktop. My guess is that syncing it with nextcloud will take ages.
I am thinking of copying all my files to the share, mounting it as a remote storage in nextcloud, and then pointing the desktop nextcloud folder to the directory I copied the files from.
Is this the correct way to do it?
The reason I'm asking is because I'm worried it might cause problems due to timestamp differances (maybe)? or corrupt some of the data. This is what happened to me with syncthing...

Thanks in advance

HannesJo Thank you, but unfortunatly, what you're suggesting is way over my abilities, especially on a production system.

macom Thank you for your reply. If I mount the external SMB share to nextcloud, won't all the data there be accesible from anywhere?

Yes. Is that not your intention?

Yes, but I want to expose only part of the data to nextcloud. So I guess the question is can I mount the external SMB on a folder to folder basis, or is it just the whole share?

Thanks

You need to create one shared folder for each folder you want to share.

It is possible to create a shared folder folder pointing to a folder that is inside another shared folder.

Ok, I'll try to do it this way.

Thank you
