summary
Beginner‑level workshop that claims operators are controllers + custom resources + domain knowledge and demonstrates building an operator end‑to‑end using Operator SDK, packaging and install via Operator Lifecycle Manager and publishing on OperatorHub.io. Shows a concrete L5 operator that auto‑installs PostgreSQL, runs a job to seed the database before app pods start, and implements upgrade, backup and scaling patterns. Walks through scaffolding commands, CSV/Subscription workflow, five capability levels, and provides hands‑on exercises and a working demo.
