部署定制的kube-scheduler

Question

我使用https://kubernetes.io/docs/tasks/administer-cluster/configure-multiple-schedulers/部署kube-scheduler。

我在一开始完全遵循了这些步骤，但是它并没有使用"my-scheduler“来调度节点，而是节点处于挂起状态。

"my-scheduler“pod的日志为

它似乎没有访问资源的权限。我试着按照链接所说的那样配置了RBAC，但是没有帮助。

如果你曾经尝试过这个方法，请帮助我。

我不知道为什么新的调度程序使用"system:serviceaccount:kube-system:default“而不是"system:kube-system”。快速解决方案是：

kubectl create clusterrolebinding --user system:serviceaccount:kube-system:default kube-system-cluster-admin --clusterrole cluster-admin
