kubernetes 1.15安装部署metrics-server插件v0.3.6

      正常部署后查看日志有报错   manager.go:111] unable to fully collect metrics: [unable to fully scrape metrics from source kubelet_summary:node1: unable to fetch metrics from Kubelet node1 (node1): Get https://node1:10250/stats/summary?only_cpu_and_memory=true: dial tcp: lookup node1 on 10.96.0.10:53: no such host, unable to fully scrape metrics from source kubelet_summary:node2: unable to fetch metrics from Kubelet node2 (node2): Get https://node2:10250/stats/summary?only_cpu_and_memory=true: dial tcp: lookup node2 on 10.96.0.10:53: no such host, unable to fully scrape metrics from source kubelet_summary:master: unable to fetch metrics from Kubelet master (master): Get https://master:10250/stats/summary?only_cpu_and_memory=true: dial tcp: lookup master on 10.96.0.10:53: no such host]

        默认的deploy文件有坑，需要修改metrics-server-deployment.yaml （添加command红色部分）
