Today I tried to setup a small Kubernetes cluster on top of 3 Raspberry Pi 4 (4GB Memory). Here is the steps to install the cluster.
I have 3 Raspberry Pi 4 stacked with PoE headers and connected to a PoE switch at home. The are connected to Internet through a home router. All Pis are equipped with a 64GB Samsung SDXC card flushed with Ubuntu 20.04 image.

Infrastructure-as-Code is a principal that drives modern DevOps practice. I discuss the current state of Terraform and provide some basic guidelines/principles regarding how to structure it's usage for your project.
| 1. install kind: | |
| go or go1.20.3 install sigs.k8s.io/[email protected] | |
| 2. create a 3-node worker cluster by creating a yml file like this: | |
| kind: Cluster | |
| apiVersion: kind.x-k8s.io/v1alpha4 | |
| nodes: | |
| - role: control-plane | |
| - role: worker |
