Install and learn Kubernetes at home with hands-on examples and live demos for popular add-ons like Dashboard, Ingress, Grafana, Prometheus, Nfs, Cert-manager and more

Kubernetes at home for fun and education

Homekube.org aims to set up a full operational kubernetes environment on a baremetal Ubuntu server. The focus is getting something done first and improve your kubernetes skills step by step along a happy path.

Following this tutorial you should have Kubernetes and a sample application installed along with the most useful and popular administration components on your local Ubuntu server(s):

App	Tutorial	Service (AMD64)	Service (ARM64 /Raspberry)
'Who am I' echo service	whoami.md	live	live
Kubernetes dashboard	dashboard.md	login demo/demo	login demo/demo
Grafana monitoring	grafana.md	login demo/demo	login demo/demo
Prometheus metrics	prometheus.md	live	live
Testing payloads and response times	workload-testing.md	Grafana open 'Request Handling Performance'

Project philosophy

There are many ways to install Kubernetes locally but for simplicity we'll follow Ubuntu's recommended MicroK8s installation recipes. With just a few commands we will setup a Kubernetes single node locally. For all further installs we'll primarily use helm commands so we are very close to what you'd do in a cloud environment. For more complex setups including Multi-Host Multi-Cluster on a pile of Raspberrys see also the installation variants.

Requirements

Server requirements are:

• A 64bit PC or arm64 (e.g. Raspberry 4) or a Virtual Machine on any supporting OS
• An Ubuntu 20.04 LTS (18.04 LTS or 16.04 LTS will do also or alternatives linux distros supporting snapd)
• At least 20G of disk space and 4G of memory are recommended
• An internet connection
