You can conduct the following Red Hat Enterprise Linux CoreOS (RHCOS) tasks as a cluster administrator:

• LEARN about the next generation of container operating system TECHNOLOGY for single-purpose containers.
• Choose how you want Red Hat Enterprise Linux CoreOS (RHCOS) to be configured.
• Select a deployment method for Red Hat Enterprise Linux CoreOS (RHCOS):
  • Deployment that is pre-configured by the installer.
  • Deployment based on user preferences.

The Ignition configuration files you'll need to deploy your cluster are CREATED by the OpenShift Container Platform installation software. During the initial configuration of Red Hat Enterprise Linux CoreOS (RHCOS), Ignition is used to do basic disc functions such as partitioning, FORMATTING, writing data, and configuring users. Ignition reads its configuration from the installation media or the place you provide on the first boot and applies it to the machines.

You may learn how Ignition works, how to install a Red Hat Enterprise Linux CoreOS (RHCOS) server in an OpenShift Container Platform cluster, see Ignition configuration files, and ALTER Ignition configuration after it has been installed.
