Setting up multiple Raspberry Pis for a cluster can be time-consuming if done individually. This lesson teaches you how to clone the Raspberry Pi OS from one Pi to others, streamlining the setup process for your cluster.
Cloning the operating system (OS) from one Raspberry Pi to others in your cluster has several benefits:
Before cloning, you’ll need:
/dev/sdx
/dev/sdy
sudo dd if=/dev/sdx of=/dev/sdy bs=4M status=progress
sudo raspi-config
Cloning the Raspberry Pi OS for a cluster setup is a practical approach to quickly and efficiently prepare multiple Raspberry Pis for Docker Swarm. By ensuring each node starts with an identical setup, you streamline both the initial deployment and future maintenance of your cluster. Next, we’ll move on to initializing Docker Swarm on your newly prepared Raspberry Pi cluster.
