HomelabOS is a tool for deploying self-hosted services on a server. For this installation, you will need:

• Raspberry Imager
• Latest ubuntu-preinstalled-server-arm64 from here: https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial/releases
• Docker on your PC (your user should be in the docker group, sudo usermod -a -G docker username)
• Latest HomelabOS zip from here: https://gitlab.com/NickBusey/HomelabOS/-/tags

Installing Ubuntu

We will need Ubuntu 18.04 on the Raspberry. Here’s how to install it.

Fixing firmware

First, open up Raspberry Imager and flash Raspbian to your SD card. Boot up your RPi 4 and run these commands:

sudo apt-get update && sudo apt-get dist-upgrade -y
sudo rpi-update
sudo rpi-eeprom-update -a

Actually installing Ubuntu

Now, use Raspbian Imager to flash the IMG file for Ubuntu Server 18.04 to your SD card. Boot up your Raspberry and check for working SSH (default user and password are ubuntu, ubuntu). You will need to configure an SSH key if you don’t have one, so ssh-keygen and ssh-copy-id are your friends. A static IP would also be convenient, you can use netplan to configure it, it’s easy!

Installing HomelabOS

Extract files from the downloaded ZIP on your PC. Now cd to the HomelabOS directory and run the following:

make logo
make config # answer some questions
make set enable_miniflux true # miniflux is a feed reader
make

This should accomplish the following steps:

1. Build Docker images for HomelabOS
2. Set some configuration variables and create settings/config.yml
3. Enable a service, it doesn’t have to be miniflux, I chose that for testing
4. Deploy the configured services to your Raspberry
