Here is the docker-compose file I'm using (I reverse proxy http://localhost:3000 on the host):

services:  
  haven:  
    container_name: haven  
    image: ghcr.io/ancsemi/haven:latest  
    ports:  
      - 127.0.0.1:3000:3000  
    volumes:  
      - ./data:/data  
    environment:  
      - PORT=3000  
      - FORCE_HTTP=true  
    restart: unless-stopped
