Docker, Docker Compose, and Kubernetes covered from first principles through to production patterns. Guides show you how containers actually work under the hood, how to write Dockerfiles that do not bloat, how to structure Compose stacks that survive upgrades, and when Kubernetes is genuinely the right tool versus when it is massive overkill. Every tutorial is built around a running service, not a hello world container that does nothing useful. If you want to understand the difference between an image and a container, why your volume mounts keep breaking, or how to move from Compose to k3s without pain, start here.
The Commands That Actually Matter Docker has over 50 commands. You’ll use about 10 of them regularly. The rest are either for building images, managing swarm clusters, or edge cases you’ll look up once a year. This guide covers the 10 commands I run most frequently across six Docker hosts, with the flags I actually […]

What Docker Compose Actually Is (and Isn’t) Docker Compose is a way to define and run multi-container applications using a single YAML file. Instead of typing out long docker run commands with a dozen flags, you describe what you want in a file called docker-compose.yml and run docker compose up -d. That’s it. From the

Why Debian 12 for Docker Debian is what Ubuntu is built on, but without the extras. No snap packages, no Ubuntu Pro nag screens, no Canonical telemetry, no systemd-resolved stub resolver causing DNS headaches in containers. It’s a leaner, more predictable base for a Docker host, and there’s a reason it’s the default choice for

Why Docker on a Raspberry Pi Makes Sense I have three Raspberry Pis running Docker in my homelab. One handles DNS and ad blocking, another runs monitoring and a dashboard, and the third runs Listmonk for newsletter management. They draw about 5 watts each, run silently, and cost less than a month of any cloud

Why Docker Is the Right Way to Run Minecraft I have set up Minecraft servers on bare metal, on VMs, on Raspberry Pis, and in Docker containers. Docker wins. Not because it is trendy, but because it solves every annoyance you will hit with a bare-metal installation. From the homelab: Minecraft servers were one of

How to Run Pi-hole in Docker (DNS Ad Blocking with Docker Compose) If you are already running Docker on your server, putting Pi-hole in a container is the obvious choice. Your DNS service gets the same isolation, portability, and reproducibility as every other service in your stack. You can version control the compose file, blow

Why Ubuntu 24.04 Is the Docker Host You Want I run Docker across six hosts in my homelab, from mini PCs running Proxmox VMs to Raspberry Pis tucked behind the TV. Every single one of them started the same way: a clean Ubuntu install and a Docker setup that takes about ten minutes. From the

K3s: Real Kubernetes on a Raspberry Pi Let me be honest upfront: running Kubernetes on a single Raspberry Pi is over-engineered. For running a few containers, Docker Compose is simpler, lighter, and more appropriate. If your goal is purely practical — get services running with minimum fuss — you don’t need Kubernetes. That’s not the
