Question

A city data team needs managed Postgres for an application. A Postgres Operator is installed and exposes a custom Postgres resource. What should the app team create to consume that capability?

Accepted Answer

An instance of the Operator’s custom Postgres resource instead of hand-rolling StatefulSets. — Operators put a custom “order form” in the cluster API—you fill out the Postgres CR and the Operator builds the machinery. Skip hand-rolled StatefulSets when that CR exists. Let the Operator reconcile the database.

Answer

A raw kubeadm configuration file that installs etcd alongside the app Deployment.
