After installing {product-title}, you can further expand and customize your cluster to your requirements through certain node tasks.
Understand and work with RHEL compute nodes.
You can add more {op-system-first} compute machines to your {product-title} cluster on bare metal.
Before you add more compute machines to a cluster that you installed on bare metal infrastructure, you must create {op-system} machines for it to use. You can either use an ISO image or network PXE booting to create the machines.
-
You installed a cluster on bare metal.
-
You have installation media and {op-system-first} images that you used to create your cluster. If you do not have these files, you must obtain them by following the instructions in the installation procedure.

Understand and use garbage collection.
Understand and use the Node Tuning Operator.
After you deployed your cluster to run nodes with static IP addresses, you can scale an instance of a machine or a machine set to use one of these static IP addresses.
