Metrics server是K8S集群资源使用情况的聚合器。 metrics-server收集指标数据的方式是从各节点上kubelet提供的Summary API 即10250端口收集数据,收集Node和Pod核心资源指标数据,主要是内存和cpu方面的使用情况,并将收集的信息存储在内存中,所以通过kubectl top不能查看资源数据的历史情况,其它资源指标数据则通过prometheus采集...
NodeHasSufficientPID节点有足够的PID NodeNotReady节点未准备好 k8s 节点可分配资源限制 Node Allocatable 官方文档 前言 默认kubelet没配置资源预留应用没做应用资源限制情况下,那host上所有资源都是可以给pod调配使用的,这样很容易引起集群雪崩效应,比如集群内有一台上跑的pod没做resource limt导致占用资源过大导致将宿...

k8s 线上集群中 Node 节点状态变成 NotReady 状态,导致整个 Node 节点中容器停止服务。 一个 Node 节点中是可以运行多个 Pod 容器,每个 Pod 容器可以运行多个实例 App 容器。Node 节点不可用,就会直接导致 Node 节点中所有的容器不可用,Node 节点是否
