 I'm Mark Schmidt with the Cloud Platforms Business Unit at Red Hat, and this demo will be looking at scaling an OpenShift 4 cluster. First we'll look at manually scaling the cluster via the GUI. We have a Master 3 Worker node cluster. Simply select the Administration tab, and then select Machine Sets. The OpenShift cluster API project. Select the actions drop down and simply edit the count. Next we'll look at auto-scaling the cluster. First we'll take a look at the nodes we have deployed as we want the naming structure to match when we create the machine auto-scaler. You'll note that in the ammo file for the machine auto-scaler we have a Max of 20 machine set. Next we'll issue the command line to create the machine cluster in the OpenShift cluster API project. Next we'll define and create a cluster auto-scaler. Now I'll create a project prior to kicking off an auto-scaling event. Next we'll create an auto-scaling event that will create a job with more pods than the auto-scaler can handle, and we'll see the number of machines scale up to the Max in the cluster machine auto-scaler config. After about 20 minutes the load starts to subside some and you see the cluster is starting to scale down. After approximately 45 minutes the load is finished running and the cluster scales back to its original configuration of three workers.
