目前，Kubernetes 的规模上限是 5k 节点，因此您可能无法用它来管理像 10k 节点这样的 web 级集群。

您是否想知道 Kubernetes 无法管理 5k 以上节点的性能瓶颈是什么？要想将其可扩展性提升至新水平，您应该先解决哪方面的问题？Etcd、apiserver 还是调度程序？

弄清这些问题是加速运行大型 kubernetes 集群的关键。在阿里巴巴，我们会遇到各种各样的问题，比如随着集群扩展，pod 创建变得极其缓慢。在本次演讲中，我们将分享我们是如何进行各种基准测试和性能分析的。我们又是如何对主设备进行调整/微调，并将主设备的性能提升 100 倍以上。目前，我们运行 10K 节点 kubernetes 集群同运行 2k 节点集群一样流畅。
