disable systemd-resolved stub

First, disable systemd-resolved name server stub. You can use this command to do this:

# This just changes "#DNSStubListener=yes" to "DNSStubListener=no"
sudo sed -r -i.orig 's/#?DNSStubListener=yes/DNSStubListener=no/g' /etc/systemd/resolved.conf

You also have to remove the symlink /etc/resolv.conf, and replace it with a file:

rm /etc/resolv.conf
echo "nameserver 1.1.1.1" >  /etc/resolv.conf
echo "nameserver 8.8.8.8" >> /etc/resolv.conf

Then do systemctl restart systemd-resolved. ( Source)

run pi-hole in docker-compose

I am using this docker-compose.yml file for pi-hole:

version: "3"

# More info at https://github.com/pi-hole/docker-pi-hole/ and https://docs.pi-hole.net/
services:
  pihole:

    dns:                          # THIS IS IMPORTANT

      - 172.198.179.1
