Pihole

You first need to free port 53 on the Pi :

sudo nano /etc/systemd/resolved.conf

[Resolve]
DNS=1.1.1.1
FallbackDNS=1.0.0.1
#Domains=
#DNSSEC=no
#DNSOverTLS=no
#MulticastDNS=yes
#LLMNR=yes
#Cache=yes
#DNSStubListener=yes
#DNSStubListenerExtra=
#ReadEtcHosts=yes
#ResolveUnicastSingleLabel=no
DNSStubListener=no

sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

sudo reboot now

Then create ./Pihole/etc-pihole/ and ./Pihole/etc-dnsmasq.d/

Now you can Install Pi-hole

Enter your modem settings and set your DNS to your pihole's host address.

You might want to restart your modem / router.

To undo the changes :

Edit /etc/systemd/resolved.conf

sudo nano /etc/systemd/resolved.conf

Comment out DNS=, FallbackDNS= and DNSStubListener=no

Remove the /etc/resolv.conf symbolic link:

sudo rm /etc/resolv.conf

Reboot.

HOW TO UPDATE

Optional if previously installed with portainer.

Create a docker-compose file with the configuration above.

Starting your pihole is then just a matter of running the following in the directory of your docker-compose.yml...

docker-compose up -d

To update to a newer version, (when a new update/container is available):

docker pull pihole/pihole

docker-compose down

docker-compose up -d
