在Kubernetes中，可以通過以下步驟為自定義調(diào)度器添加擴展插件：

1. 確保你已經(jīng)安裝了Kubernetes。如果沒有，請參考官方文檔進行安裝。

2. 創(chuàng)建一個名為custom-scheduler-plugin.yaml的文件，用于配置擴展插件。例如，你可以創(chuàng)建一個名為custom-scheduler-plugin.yaml的文件，內(nèi)容如下：

apiVersion: v1
kind: ConfigMap
metadata:
  name: custom-scheduler-plugin
data:
  plugin.yaml: |
    # 這是你的擴展插件代碼

保存上述文件后，你需要使用kubectl apply -f custom-scheduler-plugin.yaml命令應(yīng)用這個插件。這將會在Kubernetes集群中創(chuàng)建一個新的調(diào)度器，并使用你提供的擴展插件。
