Beyond staging: Implementing high-fidelity ephemeral testing with Cluster API — track: Toolbox (or Blueprints)

Timmy Carr explores why the traditional, long-lived "staging cluster" has become a bottleneck for modern platform teams. Most organizations suffer from "environment drift," where testing environments no longer reflect production reality. By leveraging the declarative power of Cluster API (CAPI) and vSphere Kubernetes Service (VKS), platform engineers can treat entire Kubernetes clusters as disposable artifacts.

Timmy shares a technical blueprint for "infrastructure as a test artifact," demonstrating:
• How to use ClusterClass to enforce production-mirror configurations across VCF.
• How to integrate CAPI into PR-driven workflows for automated "mirror cluster" creation.
• Strategies for testing "day 2" operations, such as CNI changes and Kubernetes upgrades, on-prem before production impact.
• How to move from static capacity to an event-driven, elastic private cloud.
