Guide: OKD 4.5 Single Node Cluster

Updated: 7/29/2020

After listening to some feedback in the chat on a recent Twitch stream and the okd-wg mailing list I decided to create a guide for installing an OKD 4.5 SNC (single node cluster). This guide will use no worker nodes and only a single control-plane node with the goal of reducing the total amount of resources needed to get OKD up and running for a test drive.

VM Overview:

For this installation, I used an ESXi 6.5 host on my local network and allocated the total virtual machine RAM usage to 22GB. ESXi 6.5 has a minimum of 4GB of RAM but you should be able to run this on an ESXi host with 24GB of RAM. Here is a breakdown of the virtual machines and network layout:

Create the okd4-services VM:

Download the Fedora Server Standard ISO and upload it to your ESXi host datastore.

Create a new Virtual Machine. Choose Guest OS as Linux and Select CentOS 7 (64-bit).
