The ODROID-N2 is an amazing single board computer:
It is available with 4GB RAM - and with an eMMC card for high speed storage and a power supply it costs less than 100 Euros.
With 4+2 ARM64 CPU cores the ODROID-N2 provides an interesting platform to operate a small Kubernetes cluster without too much worrying about the power bill.
This article explains how to setup Kubernetes on ODROID-N2 single board computers.
Since there are several options for operating system as well as Kubernetes distribution and setup method, this article makes the following decisions:
Use Arch Linux ARM64 as base operating system (this is quite lean and kept very much up to date)
Vanilla Kubernetes will be used, compiled and packaged as Arch ARM64 packages on the ODROID N2
kubeadm will be used to setup the Kubernetes cluster
CRI-O as container runtime (instead of Docker)
Single master node and 4 worker nodes
Unfortunately there is no mainline Linux Kernel support for the ODROID-N2, but Hardkernel promised to work on it.
The following features are currently not working as desired:
Previous experiences with Arch Linux ARM 64bit and Kubernetes on Raspberry Pi and ODROID (ODROID-C2 to be precise) can be found here:
