immutable-nodes-with-singleton-operator-control

Status: IN

OpenShift node management combines immutability with singleton operator governance: RHCOS nodes accept changes only through the MCO delivery pipeline (render → cordon → drain → apply → reboot), and multiple operator CRs enforce singleton naming conventions — creating a system where node state is both immutable and centrally controlled through well-known named resources.

Justifications

The MCO pipeline delivers changes to immutable nodes, and the singleton pattern ensures exactly one configuration authority — together they prevent configuration drift and split-brain
