How to define docker-compose to run nodebb in docker with non root user?

[张强]

Hi, I recently tried to run nodebb in docker, but I didn't find a suitable sample docker-compose file to define nodebb docker user non root. I tried to use PGID/PUID or user in docker-compose file, but it is not work. when I tried to use PGID/PUID in environment, the node still run as root. when I tried to use user, the node runs as user, but report error "error: Error: EACCES: permission denied, open '/usr/src/app/public/installer.css"

So is there anybody could give me some advice for it, thanks!

docker-compose.yaml

  nodebb:
    image: nodebb/docker
    container_name: nodebb
    depends_on:
      - mongodb 
    volumes:
      - appdata/nodebb/data:/data
       
    #environment:
      #- PGID=1001
      #- PUID=1001
      #- user=docker1
    user: "1001"  
    ports:
      - "4567:4567"
    restart: unless-stopped
    networks:
      - app-nodebb
