If you have no other services or docker containers using port 53/80 (if you do, keep reading below for a reverse proxy example), the minimum arguments required to run this container are in the script [docker_run.sh](https://github.com/pi-hole/docker-pi-hole/blob/master/docker_run.sh) or summarized here:
```
```bash
IP_LOOKUP="$(ip route get 8.8.8.8 | awk '{ print $NF; exit }')" # May not work for VPN / tun0
IPv6_LOOKUP="$(ip -6 route get 2001:4860:4860::8888 | awk '{for(i=1;i<=NF;i++) if ($i=="src") print $(i+1)}')" # May not work for VPN / tun0
IP="${IP:-$IP_LOOKUP}" # use $IP, if set, otherwise IP_LOOKUP
