Kubernetes Multiple Scheduler中的CSINodes问题

Question

我按照此说明https://kubernetes.io/docs/tasks/administer-cluster/configure-multiple-schedulers/尝试创建在Kubernetes上运行的多个调度程序新的kubernetes调度程序状态为running，但是日志生成此错误，并且使用新调度程序状态的pod的状态为pending

E1129 02:43:22.639372       1 reflector.go:156] k8s.io/client-go/informers/factory.go:135: Failed to list *v1.CSINode: the server could not find the requested resource

这是我的kube-scheduler的clusterrole

最后，我尝试使用16.3之前的旧版本的kubernetes，使用15.6，现在可以使用– akhmad alimudin

确定，现在我了解您遇到问题的原因。您可能试图在较旧的k8s群集（关键组件为kube-scheduler）上运行较新的kube-apiserver版本，但无法完成。如您在official kubernetes documentation中所读：

[kube-controller-manager，kube-scheduler和cloud-controller-manager

不得更新比他们交流的kube-apiserver实例用。它们应该与kube-apiserver 次要版本匹配，但是可能是较早的一个次要版本（以允许实时升级）。

示例：

kube-apiserver位于

1.13

kube-controller-manager，kube-scheduler和1.13和1.12支持cloud-controller-manager

因此，您可以使用kube-scheduler，它比当前部署的kube-apiserver小一个版本，但不更新。
