Welcome to the exciting world of Raspberry Pi, where small size doesn’t mean limited power! Today, we’re diving into the Raspberry Pi 5, a mighty mini-computer that’s perfect for an array of projects.

In this guide, we’ll focus on turning your Raspberry Pi 5 into a versatile home server & home lab using Docker, a powerful tool for running applications in lightweight containers. We’ll also explore how to enhance your setup with Docker Compose stacks from clustered-pi.com, a fantastic resource for Raspberry Pi enthusiasts.

Homelab vs. Home Server

A homelab is a collection of hardware and software used for learning and experimentation. A home server is a computer that provides services to other devices on a local network. In this guide, we’ll be setting up a home server using a Raspberry Pi 5

Preparing Your Raspberry Pi 5

Before diving into Docker, your Raspberry Pi 5 needs to be ready. Here’s how to set it up:

1. SD Card Setup: Start by flashing a Raspberry Pi OS image onto a microSD card using software like Raspberry Pi Imager.
2. OS Installation: Insert the microSD card into your Raspberry Pi and power it up. Follow the on-screen instructions to install the Raspberry Pi OS.
3. Initial Configuration: Connect your Raspberry Pi to your network. It’s advisable to set up SSH access for remote management.

How to Install Docker on Raspberry Pi 5

Docker allows you to run applications in isolated environments. Here’s how to get it on your Raspberry Pi:

1. Update Your System: Run sudo apt update && sudo apt upgrade to ensure your system is up-to-date.
2. Install Docker: Install Docker with curl -sSL https://get.docker.com | sh.
3. Verify Installation: Check Docker is installed correctly with docker --version.

A more robust way to install docker, which enables it to be run from a regular user account:

#!/bin/bash

# Elevate privileges
sudo su

# Define list of packages to install
pkgstoinstall=(libffi-dev libssl-dev python3 python3-pip)

# Update package cache and install packages
sudo apt-get update
sudo apt-get install -y "${pkgstoinstall[@]}"

# Remove the Python-configparser package
sudo apt-get remove -y python-configparser

# Download Docker convenience script if it doesn't exist
if [ ! -f /home/pi/get-docker.sh ]; then
    curl -fsSL https://get.docker.com -o /home/pi/get-docker.sh
fi

# Install Docker if not already installed
if [ ! -f /usr/bin/docker ]; then
    sh /home/pi/get-docker.sh
fi

# Add 'pi' user to the 'docker' group
sudo usermod -aG docker pi

# Unmask the Docker service
sudo systemctl unmask docker

# Fix permissions for Docker socket
sudo chmod 666 /var/run/docker.sock

# Install docker-compose if it doesn't exist
if [ ! -f /usr/local/bin/docker-compose ]; then
    sudo pip3 -v install docker-compose
fi

# Start Docker service
sudo systemctl start docker

Exploring Docker Compose

Docker Compose simplifies the process of running multi-container Docker applications. To install Docker Compose:

1. Install Dependencies: Ensure you have libffi-dev, python3-dev, and python3-pip installed; if not, run sudo apt install libffi-dev python3-dev python3-pip
2. Install Docker Compose: Use sudo pip3 install docker-compose
3. Check Installation: Verify with docker-compose --version

Utilizing Docker Compose Stacks from Clustered-Pi.com

Clustered-pi.com is a website I created to document my Raspberry Pi Cluster; it offers pre-made Docker Compose stacks tailored for Raspberry Pi. To use them:

1. Visit Clustered-Pi.com: Browse the basic Docker and Raspbery Pi setup
2. Download and Deploy: Download the stack’s docker-compose.yml file. Run docker-compose up -d in the directory containing the file to deploy the stack. The docker-compose files are available on GitHub: https://www.github.com/kevinmcaleer/ClusteredPi within the stacks folder
3. To install a stack simple change into the specific stack you want to install and run by typing:

docker-compose up -d

Managing Your Home Server

Maintaining your server involves a few key practices:

• Updating Containers: Regularly update your Docker containers to get the latest features and security patches
• Monitoring: Keep an eye on server performance. Tools like htop and docker stats can be helpful
• Troubleshooting: Familiarize yourself with logs and basic troubleshooting steps for common issues

Conclusion

Congratulations! You’ve turned your Raspberry Pi 5 into a powerful home server with Docker. This setup opens a world of possibilities, from media servers to personal cloud storage.
