For engineers, Kubernetes Installation can be a challenge since there is a huge selection of Kubernetes distributions and tools to set them up, making choosing the best one for your use case difficult. Getting started with a Kubernetes cluster requires different configuration challenges and utilities. We will discuss K3s, a very powerful lightweight Kubernetes distribution that you can install in a matter of minutes.

The K3s binary is designed to be a single binary of less than 40 MB that implements the Kubernetes API. It’s like software without excess drivers.

K3s offer the following features:

It can be run over a starting RAM of 512MB .
For edge devices, K3s is a highly available, certified Kubernetes distribution.
Even a Raspberry Pi can be used with great success.
Instead of etcd, SQLite is used as the storage backend, and Containerd is used as the default container runtime (not Docker).
With utilities like k3sup and k3d, you can easily install K3S. This post will show you how to install k3s using k3sup (ketchup), which is a lightweight utility to quickly and easily set up Kubeconfig with k3s on the local or remote machine.
