What is this about?

This gist describes how to set up standalone kubelet + CRI-O + CNI on Fedora Core 31. The goal is to place a Kubernetes Pod manifest on an single node and access the application from the network. This guide has been tested on x86-64 and armv7 deployments.

Prepare the system

Make sure the system is up to date:

dnf -y update
