[BTBS] How to customize OpenShift 4 node size and type?(OCP4)

Welcome to BTBS.
Today, I am going to install openshift v4 after customizing the replicas count and type of node.
To install, I will use openshift installer 0.16.1
In order to customize the install configuration, I need to create install-config.yaml file by this command line.
I believe you are familiar how to install ocp4 but if you are not please watch "Opnehsift 4install " video.
Let's open install-config.yaml file and update replicas count to 2 and modify platform type of worker.
You are ready to deploy OCP4. Let's do it.
