v0.4.0: Kubernetes Runtime Controllers & Watchers

Kuben v0.4.0 — Kubernetes Runtime Controllers & Watchers

Kuben v0.4.0 introduces the autonomous Kubernetes control loops, turning declarative Application specifications into running cluster workloads with continuous state reconciliation.

---

Key Capabilities

• Asynchronous Reconciliation Loop (crates/kuben-platform):
  • Continuous reconciliation using kube::runtime::Controller synchronizes declared Application state with live Kubernetes resources.
  • Automatically manages downstream Kubernetes Deployment, Service, HorizontalPodAutoscaler, and PersistentVolumeClaim manifests.
• Informer Work Queues & Memory Caching:
  • High-throughput Kubernetes reflector streams maintain an in-memory cached view of active cluster pods and deployments.
  • Debounced event queuing prevents thundering herd situations during large-scale rollout transitions.
• Autonomous Self-Healing:
  • Detects out-of-band modifications or unexpected pod crashes, automatically converging workloads back to declared specifications.
  • Rolling restart mechanisms and detailed status conditions (Ready, Progressing, Degraded).
