TechRadar guide offers step-by-step instructions for self-hosting Docker apps

TechRadar has published a comprehensive guide to self-hosting Docker apps on Linux, covering the basics of containers, Docker Engine, and Compose.

The guide explains that the number of self-hosted community projects is steadily growing, with many operating under open-source or fair-code licenses. Docker, an open-source platform, packages software into separate containers, each containing the code, libraries, and settings associated with an application. These containers have their own resource allocations, ensuring that applications cannot draw more system resources than intended or interfere with one another during runtime.

According to the guide, Docker apps are completely isolated, preventing dependency conflicts between different applications. It introduces the core concepts of Docker Engine, images, Docker Hub, and Docker Compose. Docker Engine is the core platform for isolation, while images are the project libraries used to install apps. Docker Hub serves as a public library of images, and Docker Compose is an add-on that allows multiple containers to be launched simultaneously.

The guide emphasizes the need for Docker Compose because most applications are not simple enough to run from a single container; they typically include a frontend, a backend, and databases. By creating a compose.yaml file, users can specify which containers and services need to run together, then launch the entire application with the single command docker compose up. It also explains how to use docker compose stop and docker compose down to pause or fully stop the application.

For those ready to begin, the guide outlines the prerequisites, including a Linux-based home server or VPS running a recent version of Ubuntu or Debian, root access, an SSH client, and the server's IP address and credentials. The first step is to connect to the server via SSH using the command ssh username@your-server-ip, then update the server's libraries and packages with sudo apt update && sudo apt upgrade -y.

The next step is to install Docker Engine. The guide advises installing necessary certificates and Docker's GPG key, then adding the official Docker repository to the list of package sources. These steps ensure that users pull the most recent version of Docker Engine from its official repository. After installation, users can proceed to configure Docker Compose for managing multi-container applications.

The guide also mentions that it will discuss some popular Docker apps to get users started, though the specific applications are not detailed in the published excerpt.
