k8s集群中,有pod出现了 Affinity ,使用 kubectl describe pod 命令,发现了报错2 node(s) didn't match Pod's node affinity. 复制代码 Warning FailedScheduling<unknown>default-scheduler0/2nodesareavailable:1node(s) didn't match node selector, 1 node(s) had taints that the pod didn't tolerate. 这...

Node Affinity/Selector 是一种基于标签的选择器,它会根据节点的 label 属性进行匹配。例如,如果我们设置了 Node Affinity 为 "node-role.kubernetes.io/master",则只有具有 "master" 标签的节点才能运行 Pod。如果一个 Pod 与 Node Affinity 中的标签不匹配,那么它就无法在指定的节点上运行。 然而,在实际应用中...
But using the node selector for the deployment it kept saying node(s) didn't match Pod's node affinity/selector; predicateName=NodeAffinity; reasons: node(s) didn't match Pod's node affinity/selector; I'm not sure why, I'm using EKS node group, and scale from 0 👍 3 rljohn...
在容器化部署中,node affinity/selector 是非常重要的概念,它可以确保容器在运行时能够稳定地运行在一个特定的节点上,以达到负载均衡、故障切换等目的。然而,有时候我们可能会遇到 didn’t match pod’s node affinity/selector 的问题,这会给我们带来很大的困扰。那么,我们该如何解决这个问题呢?

这次亲和性(affinity)我们选择Pod反亲和性(podAntiAffinity)。它用于表达:如果满足下面条件就不调度。 topologyKey 这儿有个非常重要的名称:topologyKey。它和labelSelector之间是与的关系,即topologyKey表达的条件要满足,labelSelector表达的条件也要满足。 topologyKey的写法非常简单,只要传入Node标签的一个Key的名称。比...
podAntiAffinity不能与nodeAffinity一起使用 我在k8s上进行了一系列部署,部署了相同的服务器二进制文件,但在规格上有所不同,如内存限制等。每个部署仅运行1个pod,并且希望为这些部署安排一个pod,以便每个虚拟机仅安排一个pod。 由于某些部署需要比其他部署更大的内存,因此我们将 nodeAffinity 和 podAntiAffinity 结合...
nodeAffinity和podAffinity、podAntiAffinity书写格式梳理 最近在学习node和pod的亲和性和反亲和性,差点被其中的写法给搞糊涂了,官方对这一块的定义比较混乱,官网文档也没有全部列举,所以专门做了一个书写格式的梳理。 https://v1-21.docs.kubernetes.io/zh/docs/concepts/scheduling-eviction/assign-pod-node/...
