How Can Pod Start-up Be Accelerated on Nodes in Large Clusters? - Paco Xu, DaoCloud & Byron Wang
如何在大型集群中加速 Pod 的启动?| How Can Pod Start-up Be Accelerated on Nodes in Large Clusters? - Paco Xu, DaoCloud & Byron Wang, Birentech
这个想法来自我最近写的博客 Kubernetes 1.27:加速Pod启动的更新。这是一个集群管理员可能面临的常见问题。本次会话将向您展示Pod启动的过程以及如何加速Pod的启动。
API:
控制器管理器创建Pod的时间,
KCM:PV和PVC绑定以及Webhooks。
调度:
GPU拓扑感知,节点负载感知。
来自kubelet方面的节点级别:
镜像拉取,Sidecar,API QPS和Burs,事件驱动PLEG,
限流,磁盘和卷驱动程序,静态CPU策略,容器运行时。
GPU管理:
拓扑不仅仅是NUMA,共享和监控。
数据负载:
数据预加载和本地存储或分布式存储。
可观察性:
如何检查为什么Pod启动缓慢?
The idea came from my recently written blog Kubernetes 1.27: updates on speeding up Pod startup. This is a common issue that cluster administrators may face. This session will show you the process of pod startup and everything about how to speed up the startup of pods.
API:
the creation time of pods by controller-manager,
KCM: PV & PVC binding and webhooks.
Scheduling:
GPU Topology-aware, node load aware
Node level from the kubelet side:
Image Pulling, Sidecar, API QPS & Burs, Event-Driven PLEG, Throttling, Disk and Volume driver, Static CPU Policy, Container Runtime
GPU Management:
Topology not only NUMA, Sharing, and Monitoring
Data load:
data preload & local storage or distributed storage
Observability:
How to check why the pod starts up slowly?
