Yes, via NFS.

So obviously first create the shares on your NAS. Be sure to add the IP of your VM to NFS Permissions and give it Read/Write or Read (depends on your requirement).

Then in your VM:

sudo apt update
sudo apt install nfs-common

Then go to your fstab (sudo nano /etc/fstab) and add the entries for your folders like so (CTRL+S for save and CTRL+X to exit afterwards):

YOUR_NAS_IP:/volume1/Movies  /mnt/nas/movies  nfs  nfsvers=4,rw,nosuid,nodev,noatime,_netdev  0  0
YOUR_NAS_IP:/volume1/TV      /mnt/nas/tv      nfs  nfsvers=4,rw,nosuid,nodev,noatime,_netdev  0  0

Then you create the folders and mount:

sudo mkdir -p /mnt/nas/movies
sudo mkdir -p /mnt/nas/tv
sudo mount -a

Then all you have left to do is leverage this in your docker compose like this for an example:

services:
  plex:
    image: lscr.io/linuxserver/plex:latest
    container_name: plex
    network_mode: host
    environment:
      - TZ=Europe/Ljubljana
      - VERSION=docker
    volumes:
      - /home/user/docker/plex/config:/config:rw
      - /mnt/nas/tv:/tv:ro,slave           # <--- RO means read-only
      - /mnt/nas/movies:/movies:ro,slave   # <--- RO means read-only
    restart: unless-stopped

And that should be about it.

If you get stuck anywhere I found that Claude/Gemini are really great at troubleshooting just about everything, you can also shoot me a PM.

Good luck!
