blinkt-k8s-pod-visualization

I frequently use my picocluster to demonstrate kubernetes or rancher to developers. It is awesome to be able to visualize the scheduling of pods across nodes using the Pimoroni Blinkt! led light bars. Who doesn't like blinking LEDs?

Quick Start

Prerequisites:

  • k8s installed on your pi cluster
  • kubectl already connected to your pi cluster
  • helm 3 installed

Install with:

helm install blinkt-k8s-pod-visualization . --set-file namespaces=../../namespaces.json --namespace blinkt

Changing namespaces and colors

The namespaces.json file at the root controls which namespaces are shown on the LEDs and the color with which they are represented. If you don't want kube-system pods represented remove that entry. If you want another namespace not mentioned tracked add an entry for it.
