Tutorial: Deep Dive into the Operator Framework for Kubernetes
Talkat KubeCon + CloudNativeCon North America 2019 · on Thursday, 2019-11-21· at 16:25· Hall D - San Diego Convention Center·
summary
Hands-on tutorial that builds two working operators: a Go-based podset operator that creates pods, stores their names in status and scales between replica counts, and an Ansible operator that deploys a Memcached Deployment and scales from 2 to 5 pods on events. Uses Operator SDK commands (new, add api, up local), Katacoda lab instances, CRDs, ownerReferences for garbage collection, and mentions OLM/operatorhub for packaging and upgrades. Claim: Operator SDK supports Go, Ansible, and Helm and lets teams ship operators quickly with local dev and lifecycle tooling.
