Setting up Node-Red in a docker container on Openmediavault 7

General

Hi there.

I am running OMV7 on my server and running various containers without any issue.

However, I am struggling to get the Node-Red container working, though I had no issue with it on OMV6.

It appears that I might have a permission issue but cannot work out, exactly, what it is.

I am using the following docker compose:

services:
  node-red:
    image: nodered/node-red:latest
    user: 1001:100
    environment:
      - TZ=Europe/London
    ports:
      - "1880:1880"
    volumes:
      - /srv/dev-disk-by-uuid-85c4513d-cfd9-4134-ad11-5d6552e81a81/appdata/node-red/data:/data

but am getting the following error:

Is there something different about the NR docker that makes it not run out of the box?

Found the solution - I needed to create the "data" folder as appuser (which I use for docker), rather than root.
