[Docker] Environment variable: PUID and PGID

Description

Hello. As i want to run more secure environment of my homelab, i don’t want to run any docker container as root.

Suggestion: Every Linuxserver image has it’s common environment variables like TZ (timezone), PUID (user ID of user that will run the container), PGID (group ID of user that will run the container). Those last two i’d like to see also in Homarr. Many docker images of countless projects have it.

Things i tried: As i’m managing my container in Portainer Web UI, i needed to select different way of achieving user definition. Docker itself has --user: 1000:1000 which defines which user will run the container.

• This can be easily done by going to Container -> Labels -> write name user and value 1000:1000. However, this didn’t work.

I don’t think PUID and GUID has anything to with NextJS, as @Pheggas said it’s just defining which user and group the docker container uses. I have no idea how to pass this to the actual container, but I’ll do some research.

hello, this does not seem to address the issue if I understand correctly … root user is still used in container and config files are created with root. my docker compose file :

---
version: '3'
services:
  homarr:
    container_name: homarr
    image: ghcr.io/ajnart/homarr:latest
    environment:
      - PUID=998
      - PGID=100
      - TZ=Europe/Paris
    volumes:
      - /home/admin/configs/homarr/configs:/app/data/configs
      - /home/admin/configs/homarr/icons:/app/public/icons
    restart: unless-stopped
    ports:
      - '7575:7575'

content of conf folder :

/home/admin/configs/homarr $ ll
