Unable to install modules on Docker

General
1

Hello, I recently tried to update some nodes via the manage palette menu, that failed and since I've been unable to install any new nodes, and some of the ones I attempted to update have disappeared.

I'm running node-red in a docker container on a raspberry pi 4, I've checked permissions and all seems fine there. I get the following message in the logs

1950 verbose stack Error: EPERM: operation not permitted, symlink '../multicast-dns/cli.js' -> '/data/node_modules/.bin/multicast-dns'

Here is the rest of the log, but I don't think there's anything relevant in it - https://textbin.net/obgntuhymu

I appreciate any help, please let me know if further info would be helpful, thank you.

Are you using Docker for a good reason? If not then don't, it just adds complexity. Instead, install node red using the recommended script. Running on Raspberry Pi : Node-RED

If you do need to do it, it seems you have a permissions problem of some sort. Possibly with /data.

No, I'm running other stuff in Docker so it was just to keep it the same. Looking through the forum it does seem like it causes a lot of issues, I'll install it directly so, thanks for replying.

Docker is great if you just need to install something and run it. The problems arise when you need to tweak it. Then you need to understand what you are doing, and there are not all that many who can help when things go wrong.

I assume you are using some volume mapping? is the underlying folder it owned by the same user that is running the container?

I suspect that is where the problem lies.

this is how I run mine (docker-compose):


---
version: "2.1"
services:
  nodered:
    network_mode: bridge
    image: nodered/node-red
    container_name: nodered
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Amsterdam
    volumes:
      - /media/dockervolumes/nodered/noderedData:/data
    ports:
      - 1880:1880
    restart: unless-stopped

and the /media/dockervolumes/nodered folder is owned by user 1000 (chown 1000:1000 /media/dockervolumes/nodered -R)
