    image: pihole/pihole:latest
    restart: unless-stopped
  environment:
    DNSMASQ_LISTENING: all

TIP

In the ports section, if you want to access the pi-hole from another container using the host's IP address, you may need to use the IPADDRESS:PORT:PORT syntax. For example:

yaml
ports:
  - 192.168.0.109:53:53/tcp
  - 192.168.0.109:53:53/ucp

Also update ~/.config/docker/daemon.json to other containers use the new DNS server:

json
{
    "dns": ["192.168.0.109"]
}

After starting the container, get the web password with:

shell
docker compose logs pihole | grep random
