If you’re reading this article, I’m presuming that you know what Pi-hole is, and have a Raspberry Pi setup with Docker installed.
Pi-hole features and benefits
I think the main reasons most people will install Pi-hole is to block ads, increase privacy, and for added security, but here’s a list of features an benefits, if setup correct and maintained:
- Block ads on your devices (e.g. ads on web pages, in apps, video ads on YouTube, ITV player, even on your TV, etc).
- Help to remain secure by preventing malware and phishing attempts.
- Block scam websites.
- Improve privacy.
- Prevent tracking.
Install Docker Compose
To check if you have Docker Compose installed, run the below command in a terminal window:
If you see the below response, run the below command to install Docker Compose:
sudo apt-get -y install docker-compose
Create a Pi-hole Docker Compose Manifest
Create and navigate to a new folder using the below commands in a terminal window:
mkdir /home/pi/pi-hole cd /home/pi/pi-hole
Create a new file using the below command:
Update the below with your password, and then paste it into the new file you created:
version: "3" # More info at https://github.com/pi-hole/docker-pi-hole/ and https://docs.pi-hole.net/ 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: 'Europe/London' WEBPASSWORD: 'EnterYourSecurePasswordHere' # Volumes store your data between container upgrades volumes: - './etc-pihole/:/etc/pihole/' - './etc-dnsmasq.d/:/etc/dnsmasq.d/' # Recommended but not required (DHCP needs NET_ADMIN) # https://github.com/pi-hole/docker-pi-hole#note-on-capabilities cap_add: - NET_ADMIN restart: unless-stopped
Press CTRL + X to close the editor
When prompted about saving the changes, press Y for Yes.
Press enter, without changing the file name.
You will return to the terminal window after the updates are saved.
Installing Pi-hole in a Docker container
In the same folder as your newly created docker-compose.yml file, as detailed above, run the below command to create a Pi-hole Docker container:
docker-compose up -d
-d is used to set the container to run as a background process.
You’ll see it start to download the files and install them, please be patient.
When you see the below, the Pi-hole Docker containter is installed.
View your Pi-hole Docker container
You can view your containers by running the below command:
If you don’t see your containter, try appending an -a to show all containers, even those not running.
docker ps -a
If everything is running, you can now start using Pi-hole by browsing the admin portal:
You will need to use the password that you saved in the docker-compose.yml above, when authenticating with Pi-hole.
When you’ve configured it, don’t forget to set your server up as the DNS server, and consider setting it as a DHCP server too. You could also keep your DHCP server, and setup Pi-hole on two Raspberry Pi’s, and set them both as DNS servers, to give you some redundancy.
Nice quick tutorial. Two issues I had was running docker without sudo. Quickly solved that and last issue was already had a bind to port 443. Quick uninstall of apache2 solved that. Works great!
