Docker is a tool that works on containerization technology. This is used to launch containers for different requirements like a webserver, a dns and many more. To know more about docker you check it out here on GeeksForGeeks and for launching your own web server on docker you could see here.
How to setup pi-hole and Docker?
Open your terminal and Start docker
sudo systemctl start docker
Enter the command to download pihole from docker hub
sudo docker pull pihole/pihole
Step 2: Skip this if you are not using ubuntu
sudo systemctl stop systemd-resolved.service
sudo systemctl disable systemd-resolved.service
Change the DNS to something else like google
sudo gedit /etc/resolv.conf
set dns 188.8.131.52 and save.
Copy this code
version: "3" services: pihole: container_name: pihole image: pihole/pihole:latest ports: - "53:53/tcp" - "53:53/udp" - "67:67/udp" - "80:80/tcp" - "443:443/tcp" environment: TZ: 'Asia/Kolkata' #this is the time zone volumes: - './etc-pihole/:/etc/pihole/' - './etc-dnsmasq.d/:/etc/dnsmasq.d/' dns: - 127.0.0.1 - 184.108.40.206 cap_add: - NET_ADMIN restart: unless-stopped
Open a File
sudo gedit pihole.sh
copy paste the above code here and save the file.
Give permissions to the shell file
sudo chmod u+x pihole
Run the file to launch pihole
Move inside pihole container
sudo docker exec -it pihole bash
Change pihole password
pihole -a -p
Go to browser and search
Use IP and copy paste the ip to browser
Login with the password
That’s it all set.
Now use the pihole as your DNS instead of any other.
Go to dns setting in your windows…
settings –> Network and Internet –> Ethernet (if you are connected to ethernet) or WiFi ( if your laptop connected to wifi) –> change adapter options –>right click on wifi or ethernet and go to properties –> select ipv4 –> properties –> change the dns to the ip of pihole.
Change the DNS from optain DNS automatically to Use following dns server and write the ip the box. In second you could write any dns like 220.127.116.11
Same Pi-hole IP can be used in the home router as DNS.
