Kubernetes Operators with Go

on YouTube ↗24m

" summary

Operators use Go and controller-runtime to build an event-driven worker that keeps current state matching desired state by a never-ending reconcile loop. Examples show an operator calling AWS via the upstream ACK IAM operator to create IAM roles and buckets, using create-or-patch to mutate child resources, using cache-backed reads to avoid API DDoS, and marking ownership with set controller reference and finalizers. Best practice is to re-queue rather than sleep so reconcile is idempotent and converges to “no changes.”
