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...
在使用affinity/selector时,需要遵循以下几个原则: 保证Pod之间的互相独立:每个Pod必须绑定到同一个节点上,这样才能保证Pod之间的互相独立。 选择合适的容器:每个Pod必须使用节点的selector来选择要运行的容器。selector描述了Pod应该运行的容器的一些属性,如服务、部署、环境等。 设置限制:可以设置Pod中运行容器的数量...
Pod 是 Kubernetes 中一个运行在一个命名空间下的所有容器的集合,而节点 affinity 是指在同一个 Pod 中,容器之间可能会被绑定到同一个或多个节点上,而 selector 则是指用于选择 Pod 中容器的特定条件。 当我们遇到 didn’t match pod’s node affinity/selector 的问题时,实际上是在说容器没有被正确地绑定...

nodeAffinity:selector:matchLabels:kubernetes.io/name:my-namespace 在上面的 YAML 示例中,Pod 的命名空间 "my-namespace" 应该与 Node Affinity/Selector 中的 "kubernetes.io/name" 标签匹配,但实际情况下可能存在错误。 当遇到这些问题时,我们应该采取以下措施来解决问题: ...
什么是 didn't match pod's node affinity/selector? 在Kubernetes 中,每个 pod 都需要一个或多个节点来执行其应用程序。为了确保 pod 能够安全、高效地运行在集群中的某个节点上,我们需要为 pod 指定一个或多个节点。节点之间的资源竞争问题,在某种程度上,可以通过 pod 的选择来解决。
