How to Setup Pi-hole in Docker for Network-Wide Ad Blocking
The Ultimate YouTube Video Description
Don't throw away your old laptop! In this video, we are rescuing a broken, reflowed Lenovo IdeaPad 3 from the trash and transforming it into a powerful, energy-efficient Home Lab server.
We will walk you through the step-by-step process of installing Docker on an Ubuntu Server running inside a Proxmox Virtual Environment (PVE) virtual machine. Once our platform is ready, we will deploy our very first container: Pi-hole! Pi-hole acts as a network-wide Domain Name System (DNS) sinkhole that blocks annoying advertisements and trackers before they even reach your devices.
Real-world tech isn't perfect, and things WILL break! I won't hide the struggles. Together, we will troubleshoot common real-world administrative hurdles, including:
Fixing user permissions so you don't have to type Superuser Do (sudo) every single time.
Resolving Port 53 conflicts by disabling the built-in systemd-resolved service.
Resetting the Pi-hole web User Interface (UI) password directly from the Command Line Interface (CLI) using Docker executive (docker exec) commands.
Fixing the "No Internet" routing issue by switching to expert mode and permitting all network origins.
By the end of this tutorial, we will configure our Internet Service Provider (ISP) router to distribute our new server's Internet Protocol (IP) address via Dynamic Host Configuration Protocol (DHCP) and disable Internet Protocol version 6 (IPv6) to prevent DNS leaks. The result? A completely ad-free home network powered by upcycled hardware!
