NodeSelector 是 Kubernetes 中的一个概念,它允许用户通过标签选择器(label selectors)来指定 Pod 应该被调度到哪些节点上运行。这一机制为Pod的调度提供了灵活性,使得用户可以根据节点的标签属性来控制Pod的分布。 为什么使用NodeSelector? 通过NodeSelector,我们可以指定固定节点运行服务 ...
使用nodeSelectors启动守护进程的一个示例场景是在Kubernetes集群中运行一个需要与特定硬件设备交互的后台进程。可以通过给节点打上特定的标签,然后使用nodeSelectors将具备特定硬件设备的节点选中,并在这些节点上启动守护进程。 在腾讯云产品中,可以使用腾讯云容器服务(Tencent Kubernetes Engine,TKE)来管理和部署Kubernetes集群...

此时需要分析本pod 采用了什么调度方式。从以上信息可以找到Node-Selectors: run=pro采用了 NodeSelector 方式调度,调度到node节点标签为run=pro的。那我们查询一下 node 上的标签信息有没有。 -># kubectlgetnodes--show-labels NAME STATUS ROLES AGE VERSION LABELS21.host.com Ready master,node32d v1.15.9...
It would be interesting to implement some kind of security via nodeSelector for persistent volumes. Essentially the volume would have specific selectors defined and a pod requesting a volume (claimed within the project) should only be scheduleable on a node with matching selectors for both the ...
