В: Настройка плагина настраиваемого планировщика в Kubernetes

Я пытаюсь добавить свой собственный планировщик с плагином планировщика в Kubernetes. Из-за отсутствия подробного примера в документе Kubernetes (scheduling-framework, 20180409-scheduling-framework < / а>)

Так что я просто сделал это для тестирования. Но я получил error: unable to recognize "test.yaml": no matches for kind "KubeSchedulerConfiguration" in version "kubescheduler.config.k8s.io/v1alpha1".

Как я могу настроить и использовать плагин планировщика?

В моем случае тестовые конфигурации

apiVersion: kubescheduler.config.k8s.io/v1alpha1
kind: KubeSchedulerConfiguration
plugins:
  queueSort:
    enabled:
    - name: test

pluginConfig:
- name: test-

команда kubectl

$ kubectl apply -f test.yaml
error: unable to recognize "test.yaml": no matches for kind "KubeSchedulerConfiguration" in version "kubescheduler.config.k8s.io/v1alpha1"

Когда я создал как под,

$ kubectl create -f test.yaml
$ kubectl logs pod test

Конфигурация планировщика не применяется к серверу API с помощью команды kubectl apply, она передается процессу планировщика с помощью kube-scheduler --config=/path/to/config. Подробнее об этом читайте на Github.

--config - это запись, в которой вы должны указать, какие параметры будет принимать планировщик. С точки зрения API этот файл конфигурации должен содержать KubeSchedulerConfiguration объект:

 # content of the file passed to "--config"
 apiVersion: kubescheduler.config.k8s.io/v1alpha1
 kind: KubeSchedulerConfiguration
 clientConnection:
   kubeconfig: "/var/run/kubernetes/scheduler.kubeconfig"
 algorithmSource:
   policy:
     file:
       path: "/root/config/scheduler-extender-policy.json"

См. Эту статью, в которой описывается, как создавать собственные Планировщик Kubernetes и конфигурация Планировщика.

Спасибо!! Я мог догадаться, в чем проблема - person yotion; 29.09.2019

Я думаю, что @yotion хочет использовать структуру планирования. Однако предоставленные ссылки относятся к расширителю планировщика. - person iwita; 30.01.2020

@iwita действительно, я также ищу способ развернуть плагин с использованием API фреймворка планирования с функцией вне дерева, у вас есть какой-нибудь учебник, который вы знаете? - person repié; 19.02.2020
