A county applies an operator manifest; afterward a controller continuously reconciles custom resources toward desired state. What is the operator’s essential role?
Select an answer to reveal the explanation.
Short Explanation
An operator is the tireless clerk who reads BackupSchedule (or similar) and keeps making the cluster match what the form says. Watch, compare, act—that reconcile loop is the heart of it. It does not replace the API server.
Full Explanation
Operators implement controller patterns: they watch custom resource instances and reconcile dependencies such as Jobs, PVCs, or configuration until observed state matches the CR spec. They run as workloads with RBAC to the resources they manage. They do not replace kube-apiserver or disable core control-plane components.
