This is code, a Docker image, and Kubernetes DaemonSet for the Pimoroni Blinkt! lights kit, in order to identify CPU load on each node in a Kubernetes cluster. This has been tested with HypriotOS on the RPI 3 B. The Python program is based on the Blinkt! cpu_load.py example, which can be found here.
This is very much not done yet! I hope to finish it soon! In the meantime, check out my current project, a twitter trivia bot!
