Smooth Operator - A Rough Guide to Kubernetes Operators - Olive Power, VMware
summary
Defines operators as controllers for custom resources that codify operational knowledge into Kubernetes API actions, with concrete examples like database clustering (CockroachDB) where operators handle instance join, cache flush and failover. Recommends tooling: kubebuilder and Operator Framework to generate boilerplate and implement reconciliation logic, languages used include Go Java and Ansible, and registries like OperatorHub.io plus live walkthroughs (TGI Kubernetes episodes 7 40 83) for step‑by‑step kubebuilder demos.
