Writing Robust Kubernetes Operators in Go: Beyond the Basics
A deep dive into controller-runtime loops, informer caches, custom resource definitions (CRDs), and handling reconsolidation edge cases gracefully.
Kubernetes Operators allow us to package domain-specific operations directly into the control plane. But designing controllers that don't leak resources or loop infinitely during reconciliation failures is a challenge.
We walk through configuring rate-limited queues, optimizing status updates via subresources, and using finalizers to coordinate graceful external resource cleanups.
