The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 32.0.1
  • Operating system and version (e.g., Ubuntu 24.04):
    • Debian with Docker
  • Web server and version (e.g, Apache 2.4.25):
    • See YAML
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • nginx proxy manager (on another jumpserver)

Summary of the issue you are facing:

I have installed Nextcloud with Docker-Compose on my Debian ā€œDockerrunnerā€ VM.

This is my Portainer-Stack:

version: '2'
services:
  mariadb:
    image: mariadb
    restart: always
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW --innodb-file-per-table=1 --skip-innodb-read-only-compressed
    ports:
      - 9022:3306
    volumes:
      - /root/nextcloud/mariadb:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=PASSWORD
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=root
  nextcloud:
    image: nextcloud
    restart: always
    ports:
      - 8040:80
    links:
      - mariadb:mysql
    volumes:
      - nextcloud-html:/var/www/html 
      - nextcloud-apps:/var/www/html/custom_apps 
      - nextcloud-config:/var/www/html/config 
      - nextcloud-data:/var/www/html/data 
    environment:
      - MYSQL_PASSWORD=PASSWORD
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=root
      - MYSQL_HOST=mariadb
volumes:
  nextcloud-data:
    external: true
  nextcloud-html:
    external: true
  nextcloud-config:
    external: true
  nextcloud-apps:
    external: true

As you can see my volumes are external, as i have most of the time all docker volumes on my NAS. This are mounted via the ā€œvolumesā€ tab in Portainer.

This Docker VM is available via VPN ā†ā†’ to my Jumpserver (Debian Server hosted in a data center) and on this debian server there is an nginx proxy manager running doing my https reverse proxy and domain.

I started everything up and i installed the app ā€œexternal data storageā€ and mounted my SMB share to my files in nextcloud - this is working great and i can add and remove folders and files.

But i canĀ“t delete the ā€œstandardā€ folders and files created by the installation ā†’ on my Volume Data ā†’ on my Synology NAS (remote mounted via volumes in Portainer).

I can delete the files on the NAS directly and it will took some time and they disappear on nextcloud - or i can remove them then. But i think there are some write / read permission errors on this side.

Can you help me to fix this? IĀ“m new to nextcloud. If you need more information i can search for them. :slight_smile:

Also my SMB Share External Storage is not visible in the Nextcloud iOS App - Do i have to do more stuff on this side? In the web UI i can see them.

Thanks for your help!
