How to Install Nextcloud+Syncthing+Filebrowser in Open Media Vault 6

Install Open Media Vault 6 using this command:

wget -O - | sudo bash

Once installed, create a Samba share called ‘appdata’ containing a ‘configs’ folder and a separate Samba share for each of your users. The following nginx.conf file is to be saved in your appdata/configs folder:

worker_processes auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/;

events {
    worker_connections  1024;

http {

                      '"$http_user_agent" "$http_x_forwarded_for"';

Go to the container console in Portainer and enter the following for each of your users:

chown -R www-data:www-data /user1
chown -R www-data:www-data /user2

Also, add the following line to Nextcloud’s config.php file:

'overwriteprotocol' => 'https',

Create a Nextcloud-Proxy Stack in Portainer:

version: '3'
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
      - '80:80'
      - '81:81'
      - '443:443'

# If you are using FreeDNS and your router doesn't support it, then add the following section.
    container_name: dynamic-dns
    image: joweisberg/dynamic-dns:latest
    restart: unless-stopped
      - TZ=America/Los_Angeles
      - USER="username"
      - PASSWORD="password"
      - SERVICE=freedns
      - HOSTNAME=""
      - DETECTIP=1

      test: ["CMD", "/usr/bin/healthcheck"]
      interval: 30s
      timeout: 10s
      retries: 5

Log into the proxy portal on port 81 using ‘’ for the user and ‘changeme’ for the password. You will be required to change the user and password. Then create a new proxy host with the port forwarded to your Nextcloud server (port 8080) and request a new new SSL certificate.

Create a Syncthing Stack in Portainer:

version: "2.1"
    container_name: syncthing
    hostname: syncthing #optional
      - PUID=1000
      - PGID=1000
      - TZ=America/Los_Angeles

      - 22000:22000/udp
      - 21027:21027/udp
    restart: unless-stopped

Create a File Browser Container in Portainer:

Name=Filebrowser: The name of the container. This is important because you can have several containers based on the same image.
Restart=always: Restart the container if it stops. If it stops manually, it is only restarted when the container is manually restarted, or the Docker service is restarted.
Port 8086:80: File Browser exposes port 80 for File Explorer access. As port 80 is usually used for any Web service; We indicate that port 80 of the container is exposed for example in port 8086. In this way we make other services that want to use port 80 to use it.
Volume /:/srv: Links a folder on the server (left), with a folder on the container (right). File Browser uses by default the internal root /srv folder to display in the file explorer. By indicating the root / in the server folder, we indicate that we want to show all the files on the server.
Environment Variable TZ='America/Los_Angeles': The time zone of the container machine. Optional. It is very useful so that the logs and notifications are with the local time.
filebrowser/filebrowser:latest: Indicates the image used to mount the container. If no version is indicated, it will take the latest stable version.
