  -e BIND9_USER=bind \
  --restart always \

Testing:

Once running, you can test DNS resolution using dig (or nslookup) pointing to your host machine's IP address and the mapped port:

# Example query for ad.test on host port 30053
dig @127.0.0.1 -p 30053 ad.test

3. Running with Docker Compose
For persistent deployment, use Docker Compose. Since the configuration is built into the image, the Compose file is cleaner, only focusing on ports and environment variables.

File: docker-compose.yml

```services: 
  bind9: 
    image: johnneerdael/bind9-custom:latest 
    container_name: bind9
    # Environment variables baked into the Dockerfile but confirmed here
    environment:
      - TZ=Europe/Amsterdam
      - BIND9_USER=bind
      # Map the host port 53 to the container's internal port 53
    ports:
      - "53:53/udp"
      - "53:53/tcp"
    # If systemd-resolved causes issues change the ip below to the real ip and it will boot
    # ports:
    #   - "127.0.0.1:53:53/udp"
    #   - "127.0.0.1:53:53/tcp"    
    restart: always```

Command to Start:

`docker compose up -d`
