Hardware requirements scale based on the size of your deployments. However, k3s is tested on the following operating systems and their subsequent non-major releases. K3s should run on just about any flavor of Linux. I had a look at the documentation and used the following command (using environment variable INSTALL_K3S_VERSION) in order to specify a particular version of K3s to download from github: curl -sfL | INSTALL_K3S_VERSION=v1.0.1 sh -īefore setting up my demo environment I had a look at the k3s requirements. K3s packages required dependencies, including:Īccording to the website, installing k3s won’t take long.

External dependencies have been minimized (just a modern kernel and cgroup mounts needed).

In-tree cloud providers and storage plugins have been removed.

This allows K3s to automate and manage complex cluster operations like distributing certificates.

Operation of all Kubernetes control plane components is encapsulated in a single binary and process.

Simple but powerful “batteries-included” features have been added, such as: a local storage provider, a service load balancer, a Helm controller, and the Traefik ingress controller.

External datastores such as PostgreSQL, MySQL, and etcd are also supported.

An embedded SQLite database has replaced etcd as the default datastore.

K3s is a fully compliant Kubernetes distribution with the following enhancements: Easy to install, half the memory, all in a binary less than 40mb. In this article, I will share with you the steps I took, to get k3s installed (with the Kubernetes Dashboard) on top of an Ubuntu guest Operating System within an Oracle VirtualBox appliance, with the help of Vagrant.

This demo environment uses a Vagrantfile, scripts and Kubernetes manifest (yaml) files. In November of last year, my colleague Lucas Jellema, wrote an article with the title “Ultra fast, ultra small Kubernetes on Linux – K3S beating minikube”.įor training and demo purposes, on my Windows laptop, I already had an environment with a guest Operating System, Docker and Minikube available within an Oracle VirtualBox appliance.
