Talkat KubeCon + CloudNativeCon North America 2022 · on Thursday, 2022-10-27· at 11:00· 330 AB, Huntington Place: 1 Washington Blvd·
summary
Hands-on tutorial builds a CRUD operator in about 90 minutes, generating CRDs and controller scaffolding with kubebuilder + make run, deploying an app, exposing it via a Service, updating replicas and deleting the resource. Uses an online Instruct lab (access for at least one week) to avoid local Docker setup. Covers operator-sdk/operator-framework background, customize templating, and workarounds for Docker Hub rate limits by switching to an ECR-hosted image so the demo completes.
