Cluster HAT

Scripts and files used to build Cluster HAT images from Raspbian.

Installation

Please add the software sources first:

sudo apt install lsb-release wget
echo "deb http://repo.vitexsoftware.com $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/vitexsoftware.list
sudo wget -O /etc/apt/trusted.gpg.d/vitexsoftware.gpg http://repo.vitexsoftware.com/keyring.gpg
sudo apt update

Then you can install packages:

• clusterhat-image - Image Creator
• clusterctl - Clusterctl
• clusterctl-usbboot- USB Boot support for clusterctl

Usage

Simply run

clusterhat-creator

to download initial images and build ClusterHat ones

ClusterCTL

Install package clusterctl for /usr/sbin/clusterctl commad

You can also turn several PiZeros using chtui command

sudo /usr/sbin/chtui

Note: PiZero state is restored at the host boot using /lib/systemd/system/clusterctrl-state.service

Building Cluster HAT Images

The build script is located in the build directory.

The following is normally ran as root on a fresh Raspbian images.

git clone https://github.com/burtyb/clusterhat-image
cd clusterhat-image/build/
# Create a config-local.sh file and copy any lines you need to override from config.sh
./create 2017-09-07

The "2017-09-07" date above should be the date from the Raspbian/Raspberry Pi OS image you wish to convert.

When building arm64 images you need to be on an arm64 machine.

Building on x86_64

Images can be built from other architectures using qemu (tested on x86_64 but may work on others)

For example on Debian 12 to do this you need to "apt install qemu-user-static".

Then follow the standard steps

Cluster HAT Files

The files/ directory contains the files extracted into the root filesystem of a Cluster HAT image.
