Creating Resource Quotas in OpenShift 4

Welcome to the lab. You are the OpenShift admin working at the ZLand BioTech firm where you are in charge of supporting the developers creating an early screening software that is going to revolutionize the industry for tracking symptoms of the dreaded the infamous Virus Z-19. This software is vital to the early warning system and tracking of the virus. Your job is to assist the developers in managing and creating the applications that make up the screening and tracking software. Tallahassee is using too much of the cluster's resources. Create a computer resource quota to limit the resource abuse. Let's begin! >**Note:** This lab is meant to be run on your local environment. This will not work in our current Cloud Playground or Lab environment.
