• Self-Hosted Headaches with Caddy, Dynmap, and Docker!
  As some of you may know, I love Minecraft!

  I run a Forge-modded server for some friends and use a mod called Dynmap (which is also a popular plugin by the same name). This mod allows players to view a map of the entire Minecraft world in their browser and see the locations of other players.

  This had been working out beautifully until our world started to grow rather large in file size. You see, Dynmap renders/generates map tiles based on chunks in your world and the larger your world is, the more map tiles there are. For some context, my world is about 9GB and the Dynmap files that make up the map come in around ~43GB.

  That’s a lot of space! And I knew that was going to be an issue as our world grew.

  I manage my Minecraft server using AMP and it lives within an Ubuntu virtual machine dedicated to Minecraft, which lives on a node in a Proxmox cluster.

  I could have just assigned more space to the VM and called it a day (which is what I did as a short-term solution), BUT I have a NAS with lots of space hosted on another node within the same Proxmox cluster, on the same local network, and I began to wonder if there was a way to offload the storage component of Dynmap from the Minecraft server to the NAS.

  As it turns out, there is!

• Docker Compose: A Beginner’s Guide
  

  Docker Compose is a tool for defining and running multi-container Docker applications. It allows developers to define the services that make up their application and how they interact with each other, all in a single file. In this article, we’ll cover everything you need to know to get started with creating a Docker Compose file, including examples of how to define services and configure networking.

  Some Prerequisites:

  Before we dive into creating a Docker Compose file, let’s make sure you have the necessary prerequisites:

  • Have Docker installed
  • Have a basic knowledge of Docker: Familiarize yourself with Docker and its concepts

  How to Create a Docker Compose File

  A Docker Compose file is a YAML file that defines the services, networks, and volumes for your Docker application.

  The beginning of a Compose file always starts with the version key. This key is used to specify the version of the Docker Compose syntax being used in the file. This is important because Docker Compose has gone through several major revisions, and each revision introduces new features or changes to the syntax.

  Currently, the latest version of the Docker Compose syntax is version 3.9. When you specify the version tag as “3.9”, Docker Compose will use the latest syntax and recognize all of the latest features and syntax changes.

  After defining the version of the Compose file it’s time to define the services that will be run in the containers.

• Self-Hosting with Docker! 🐳
  Recently I moved my home lab environment over to Proxmox and started containerizing all of my services.

  I’ll admit, when I first started playing around with Docker I was confused as hell!

  At its core, it’s all pretty simple but you can get lost in abstraction pretty quickly if you let yourself get side-tracked. That being said, let’s get on track!

  I’m going to use Docker Compose to create a “stack”

  Docker Compose is a tool for defining and running multiple Docker containers at once. It allows you to create, start, and stop containers with multiple interconnected services, such as databases, web servers, and APIs, all using a single YAML file.

  Okay, so what is a stack you ask?

  A stack is basically a grouping of services that you have configured in a single Docker Compose/YAML file.

  Our stack will be called HostedMediaServices and will be used to serve our media libraries out to our local network (and beyond). This will include Plex (for sharing movies and TV shows), Komga (for sharing comic books/manga), and FireShare (for sharing small, self-hosted clips with unique links).

  The full compose file is available on my GitHub.

  If you want to follow along, you’ll need a couple of things:

  • Linux (I’m using Ubuntu, you can use whichever distro you’d like)
  • Docker (you’ll need Docker-Compose as well, which comes bundled with Docker Desktop)
  • A text editor – anything will work, really, but I would recommend either VSCode or Sublime Text.

  To get started, let’s break down what a Docker-Compose file actually IS.
