简介：Corndns是一种开源的DNS服务器，它可以帮助用户在Kubernetes集群中提供高可用性和高性能的DNS服务。本文将介绍如何在华为云K8s集群中配置Corndns，以实现更好的DNS服务。

一、安装Corndns

在华为云K8s集群中安装Corndns，需要先创建一个名为"corndns"的Pod。在kubernetes-deployer-deployments.yml文件中添加以下内容：

```

apiVersion: apps/v1

kind: Deployment

metadata:

name: corndns

spec:

replicas: 1

selector:

matchLabels:  app: corndns

template:

metadata:  labels:    app: corndnsspec:  containers:  - name: corndns    image: aliyunsfc/k8s-corn-dns    imagePullPolicy: Always    command: ["--service-cluster-ip", "127.0.0.1", "--service-external-ip", "0.0.0.0", "--service-port", "53", "--service-host", "0.0.0.0"]    env:    - name: CORNDNS_IP_ADDRESS      value: 127.0.0.1    - name: CORNDNS_EXTERNAL_IP_ADDRESS      value: 0.0.0.0    - name: CORNDNS_PORT      value: 53    ports:    - containerPort: 53    - containerPort: 10011  - name: corndns-etc    image: aliyunsfc/k8s-corn-dns    imagePullPolicy: Always    command: ["--service-cluster-ip", "127.0.0.1", "--service-external-ip", "0.0.0.0", "--service-port", "53", "--service-host", "0.0.0.0"]    env:    - name: CORNDNS_IP_ADDRESS      value: 127.0.0.1    - name: CORNDNS_EXTERNAL_IP_ADDRESS
