Kubernetes on Raspbian

This repository holds the original tutorial for "Kubernetes on Raspbian" / Raspberry Pi by Alex Ellis

This guide is part of a larger blog post: Build your own bare-metal ARM cluster.

Start the guide

Pick between k3s or kubeadm.

1) Pick k3s (recommended)

My current recommendation is to use k3s from Rancher Labs. It is normal Kubernetes and passes the conformance tests written by the CNCF. I'm yet to be convinced of why someone wouldn't use this for a hobbyist build and I've been pleasantly surprised by it.

k3s is:

  • faster, and uses fewer resources
  • well-maintained and ARMHF / ARM64 just works
  • still normal, upstream, compliant Kubernetes
  • doesn't appear to run into some of the complicated issues we've seen with kubeadm

Start now: Will it cluster? k3s on your Raspberry Pi

2) Or pick kubeadm (advanced users)

My current thinking is that only advanced users should attempt to install Kubernetes with kubeadm. Historically, it's had some unfortunate issues around timeouts and being slow.

Once you're up and running please share your clusters on Twitter with @alexellisuk.

You can also join the OpenFaaS Slack community's dedicated channel for ARM and Raspberry Pi #arm-and-pi. Just email alex at openfaas dot com for your invitation.
