💡 You can use all the environment configuration from the base docker image Pi-hole

The enhancement is the the unbound daemon configured to use DNS over TLS (DoT)

👉The unbound DoT upstream can be configured by the DOT_UPSTREAM environment variable

⭐Additionally the DOT_UPSTREAM environment variable can be defined by one or several user defined upstream DNS IP

  • 8.4.4.8

☝️To use the local unbound daemon DoT DNS upstream server, it can be defined by DNS1=127.0.01#5353 and DNS2=no environment variables

Docker run test example

💪In this example is used DOT_UPSTREAM, DNS1 and DNS2 environment variables

docker run --init -d --restart=always --network=eraser --dns 127.0.0.1 --ip 192.168.0.2 -e ServerIP="192.168.0.2" --hostname pihole -e VIRTUAL_HOST="pihole" --name="pihole" -e "WEBPASSWORD=admin" -e "TZ=Europe/Madrid" -e "DOT_UPSTREAM=1.1.1.1,1.0.0.1" -e "DNS1=127.0.0.1#5353" -e "DNS2=no" -e "BLOCKING_ENABLED=yes" --cap-add=NET_ADMIN --cap-add=SYS_NICE -v /opt/docker/pihole/dnsmasq.d:/etc/dnsmasq.d/ -v /opt/docker/pihole/pihole:/etc/pihole juampe/pihole-dot
