[BUG] Environment variable `HOME` points to `/root`

[userid0x0]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Hi,
I noticed that the HOME variable points to /root when the webhooks are run. This may case problems for tools that read e.g. ~/.config a.s.o. . docker is an example here as it tries to read ~/.docker/config.json .

Expected Behavior

I would expect HOME points to /config as this is the folder of the user.

Steps To Reproduce

use the following hooks.json

[
    {
        "id": "testme",
        "execute-command": "/bin/bash",
        "pass-arguments-to-command": [
            {
                "source": "string",
                "name": "-c"
            },
            {
                "source": "string",
                "name": "export"
            }
        ],
        "include-command-output-in-response": true
    }
]

Then issue the webhook e.g. curl http://<host>:<port>/hooks/testme

Docker creation

services:
  webhook:
    image: ghcr.io/linuxserver-labs/webhook:latest
    container_name: webhook

      - PUID=1000
      - PGID=1000
      - TZ=Europe/Berlin
      - EXTRA_PARAM=-hotreload #optional
    volumes:
       - ./config:/config
       - /opt/compose:/opt/compose
       - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 9000:9000
    restart: unless-stopped

Container logs

nothing interesting in the logs - the output of the webhook is of interest

I think the solution is to set HOME=/config for svc-webhook

#!/usr/bin/with-contenv bash
# shellcheck shell=bash

if [[ -z ${LSIO_NON_ROOT_USER} ]]; then
+   export HOME=/config
    exec \
        s6-setuidgid abc /app/webhook \
            -hooks /config/hooks/hooks.json \
            -ip 0.0.0.0 ${EXTRA_PARAM:=-hotreload}
else
    exec \
        /app/webhook \
            -hooks /config/hooks/hooks.json \
            -ip 0.0.0.0 ${EXTRA_PARAM:=-hotreload}
fi
