![]() It is worth observing that ARM64/AArch64 and x86_64 architecture differs, and Kubernetes nodes running on 64-bit ARM architecture cannot run container images built for x86_64. This is why Ubuntu 20.04 ARM64 image is so helpful. Systems with AArch64/ARM64 architecture can run 32-bit ARM images, but the opposite is not: 32-bit ARM systems cannot run 64-bit container images. Most container images labeled AArh64 will run on systems labeled ARM64. AArch64 vs ARM64 64-bit vs32-bit ARM vs x86Īlthough AArch64 and ARM64 are effectively the same, their different names arise from their use within diverse communities. Ubuntu 20.04 lets you use 64-bit container images with Kubernetes and its ARM64. Since the goal is to use the Raspberry Pis for running a Kubernetes cluster, running AArch64 container images is essential: it can be challenging to find 32-bit images for common software or even standard base images. Ubuntu 20.04 offers a Raspberry Pi-focused 64-bit ARM (ARM64) image with a 64-bit kernel and userspace. ![]() ![]() This tutorial will show you how to install a Kubernetes 1.18.2 cluster on three or more Raspberry Pi 4s running on Ubuntu 20.04. Installing a Kubernetes cluster on Raspberry Pi Running a local Kubernetes cluster on Raspberry pi hardware is a great way to gain experience managing and developing on an actual cloud technology giant. Kubernetes manages containers from the micro-scale at the edge to the massive scale in public and private cloud environments.
