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
-
Plain 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:
