What is an Operator?

An Operator is a Kubernetes controller that manages a stateful application. It uses Custom Resource Definitions (CRDs) to define desired state and a reconciliation loop to drive actual state toward desired. The etcd operator, Prometheus operator, and database operators automate complex Day 2 operations.
