[Issue]: group_add doesn't support integer in Compose v2

[SyRaza]

Please describe your bug

I reinstalled my server yesterday from scratch and of course installed docker and docker compose as per the website. Docker Compose v1.2.9 was still the primary install version yesterday, with the option to install Docker Compose 2.4.1.

As of today, Docker Compose 1.2.9 is deprecated and the primary installation on docker's website is Docker Compose 2.4.1.

I decided to upgrade my Docker Compose version. My docker compose yaml file worked perfectly on 1.2.9 but wouldn't run on 2.4.1.

The error I got was 'group_add[0]' expected type 'string', got unconvertible type 'int', value: '109''group_add[0]' expected type 'string', got unconvertible type 'int', value: '109'

My Jellyfin compose configuration is the only one using group_add. After disabling the Jellyfin compose configuration in my yaml file, my file worked perfectly in compose 2.4.1

Here is my jellyfin compose configuration.

# Jellyfin - Software Media System 
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    restart: unless-stopped
    networks:

          - driver: nvidia
            device_ids: ['0']
            capabilities: [gpu]

For the time being, I've rolled back to Compose v1.2.9 until there is a fix for this.

This sounds more like a documentation issue then a server issue? If you agree I will relocate the issue.

[SyRaza]

Sounds about right. I did try using the string render, instead of the integer associated with it, but that didn't work.

[Shadowghost]

According to the compose spec it supports name and number.

Can you try with the group name instead of ID?

@SyRaza
Hello,
I just had the same issue.
@zackoid help me on Discord.

If the group is 109 , you must indicate:

     group_add:
       - "109"

and no :

     group_add:
       - 109
