Notes on Building a Raspberry Pi Kubernetes Cluster

This year (2021) I’ve been building and experimenting with Kubernetes on a cluster of Raspberry Pis. This is an index to a series of posts about things that I’ve done and learned in the process.

• The Hardware
• The Nodes and Network
• Installing Kubernetes
• TLS, Ingress, and the Dashboard
• Building and Running a First App

My cluster on March 6. It hasn’t taken over the house — yet!

Future topics include a few things that I’ve done and more that I hope to do:

• Building a gRPC service
• Building a “real” app: a gRPC service backed by a PostgreSQL database with a Flutter frontend
• PostgreSQL on Kubernetes
• Running repeated tasks on Kubernetes with CronJobs
