Added Pihole and Unbound to BigBearDockerImages

So, Pi-hole is a Linux network-level advertisement and Internet tracker blocking application which acts as a DNS sinkhole and optionally a DHCP server, intended for use on a private network.

Unbound is an international nonprofit based in Kansas City, Kansas, and founded by lay Catholics grounded in the Gospel call to put the needs of the marginalized and vulnerable first

I wanted to add it to BigBearCasaOS, but there was no official Docker image available. So I added it to ‘big-bear-docker-images’ repository to store all of the Docker images that we create and maintain for BigBearCommunity.

** Port 53 **

If your port 53 is being used by systemd-resolved, then you can stop and disable it with this script:

bash -c "$(wget -qLO -"

Docker Compose

version: "3"

    container_name: pihole-unbound  # Sets a custom container name.
    image: bigbeartechworld/big-bear-pihole-unbound:2024.02.2  # Specifies the Docker image to use.

      - "53:53/udp"   # Binds UDP port 53 on the host to UDP port 53 in the container, also used for DNS.
      - "67:67/udp"   # Binds UDP port 67 on the host to UDP port 67 in the container, used for DHCP.

      DNS2: "no" # Disables secondary DNS.

    restart: unless-stopped  # Ensures the container restarts unless it is explicitly stopped.

Hey @dragonfire1119, I’ve noticed the docker image of PiHole is a few versions behind. Is there a way that I can force updates or should the docker automatically update?

Currently, the Docker image is at:

You can also check the tags here:

So I have been keeping the Docker image up-to-date. I just forgot to update the version of this post. Thanks for letting me know.

Which platform are you using?

Thanks. I’m on CasaOS and it’s not on you. I’ve installed the docker compose from the default store, not yours. My bad.

The default store doesn’t get updated as much. Also, I don’t believe the default store has Pi-hole + Unbound.

If you want to switch to BigBearCasaOS, I have videos for each app.

Hellos, Is this down? It was working fine but now has an error. And says dns resolution is not available.

Could you let me know the error?
