参照文章，十分感谢

配置文件挂载

--config 指定的是 /etc/kubernetes/scheduler-extender.yaml 鉴于云服务可能不会将权限提供给客户，所以采用configMap形式挂载 自定义调度器配置文件

// /etc/kubernetes/scheduler-extender.yaml
--- 
apiVersion: v1
kind: ConfigMap
metadata:
  name: violin-scheduler-config
  namespace: devops
data:
  application: |-
    apiVersion: kubescheduler.config.k8s.io/v1alpha1
    kind: KubeSchedulerConfiguration
    clientConnection:
      kubeconfig: "/etc/kubernetes/scheduler.conf"
    algorithmSource:
      policy:
        file:
          path: "/etc/kubernetes/scheduler-extender-policy.yaml"

而自定义调度策略文件 /etc/kubernetes/scheduler-extender-policy.yaml 我们也是基于yaml来写的

// /etc/kubernetes/scheduler-extender-policy.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: violin-scheduler-config
  namespace: devops
data:
  app: |-
    apiVersion: v1
    kind: Policy
    extenders:
    - urlPrefix: "http://127.0.0.1:8888/"
      filterVerb: "filter"
      prioritizeVerb: "prioritize"
      weight: 1
      enableHttps: false

发布多个调度器 下面文件 /etc/kubernetes/manifests/kube-schduler.yaml
