Whether running in the cloud or on-premises, workloads behave the same way without modification, and applications can move between platforms without being rewritten. This consistency is made possible by the Certified Kubernetes Conformance Program run by CNCF, which ensures distributions meet upstream Kubernetes standards. However, conformance validates runtime behavior, not how clusters are created. Cluster provisioning approaches varies widely across providers, leading to configuration drift, inconsistent upgrades, and operational complexity at scale. To address these challenges, the Kubernetes Special Interest Group Cluster Lifecycle introduced Cluster API, bringing declarative APIs to cluster provisioning and lifecycle management. In this beginner-friendly session, I will walk you through the full landscape for Kubernetes cluster creation, and share insights from a contributor’s perspective on why Cluster API exists, the problems it solves, and how community-driven effort helps make cluster creation more consistent and sustainable.
