Running Kubernetes on Workstations and Edge and IoT Devices

When it comes to running Kubernetes in resource constraint environments like your local developer workstation or edge and IoT devices a full-blown Kubernetes distribution is definitely not the right choice. Instead a new breed of super lightweight, certified Kubernetes distributions that (often) come as a single-binary are suited a lot better. In this session we will have a closer look at two popular choices: MicroK8s and K3s. We will briefly cover their basic features and then put them to the test live and uncut: locally and on my NUC powered Cloudkoffer. #CloudNativeNight #CloudNativeNerd #qaware
