cat <<EOF> my-values.yaml 
controller:
  image:
    registry: registry.cn-shanghai.aliyuncs.com
    image: wanfei/ingress-nginx-controller
    tag: "v1.1.2"
    digest:

  dnsPolicy: ClusterFirstWithHostNet

  hostNetwork: true

  publishService:  # hostNetwork 模式下设置为false，通过节点IP地址上报ingress status数据
    enabled: false

  # 是否需要处理不带 ingressClass 注解或者 ingressClassName 属性的 Ingress 对象
  # 设置为 true 会在控制器启动参数中新增一个 --watch-ingress-without-class 标注
  watchIngressWithoutClass: false
 
  kind: DaemonSet

  tolerations:   # kubeadm 安装的集群默认情况下master是有污点，需要容忍这个污点才可以部署
  - key: "node-role.kubernetes.io/master"
    operator: "Equal"
    effect: "NoSchedule"

  nodeSelector:   # 固定到master节点
    kubernetes.io/hostname: master

  service:  # HostNetwork 模式不需要创建service
    enabled: false
 
  admissionWebhooks:
    patch:
      image:
        registry: registry.cn-shanghai.aliyuncs.com
        image: wanfei/kube-webhook-certgen

    tag: "1.5"
EOF

[root@master ingress-nginx]# helm install ingress-nginx --namespace kube-system -f my-values.yaml .

[root@master ingress-nginx]# kubectl get ingressClass
NAME    CONTROLLER             PARAMETERS   AGE
nginx   k8s.io/ingress-nginx   <none>       90s

4. ingress.yaml示例

cat <<EOF> kiali-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kiali-ingress

spec:
  ingressClassName: nginx # 使用 nginx 的 IngressClass（关联的 ingress-nginx 控制器）
