Polymorphic Reconcilers in Kubernetes - Advanced DuckTyping
Talkat KubeCon + CloudNativeCon North America 2019 · on Tuesday, 2019-11-19· at 16:25· Room 16AB - San Diego Convention Center, Mezzanine Level·
summary
Shows a concrete system in Knative that uses partial schemas to reconcile heterogeneous resources: a sync binding injects a SINK env var into deployments jobs and CRDs, a mutating webhook handles immutable or controller-owned objects, and an addressable duck type standardizes where to send events. Demos use Sakai for event viewing, cronjobs stamping jobs, and a dynamic controller that watches labeled CRDs to auto-create triggers; the prototypes run end-to-end and successfully route events.
