The Force Awakens: Managing Millions of Kubernetes Clusters at the Edge
Talkat CloudOpen @ Open Source Summit Europe 2022 · on Thursday, 2022-09-15· at 16:10· Wicklow Hall 2A (Level 2), Convention Centre Dublin, Spencer Dock, N Wall Quay, North Wall Dublin 1, D01 T1·
summary
Open source classnet turns a regular Kubernetes cluster into a multi‑cluster control plane and manages edge clusters via three components: classnet agent, classnet hub and scheduler. It supports push and pull modes and optional websocket agent connections to avoid public IPs, proxies Kubernetes APIs and handles CRDs and Helm charts. A benchmark using agents-as-proxies simulates up to 1 million simulated clusters showing the hub scales but stresses kube‑apiserver and memory/socket limits, prompting a planned hierarchical parent‑cluster architecture.
