【问题描述】：

我正在尝试在我的 Azure Kubernetes 服务 (AKS) 集群上添加 argocd 入口资源。我遵循本指南https://argoproj.github.io/argo-cd/operator-manual/ingress/#kubernetesingress-nginx

当我在 kubernete AKS 集群上应用入口资源时。它给出了以下错误消息。它正在 AKS kubernete 集群上运行 v1.18.14

有人遇到过同样的问题吗？

集群环境：

Client Version: v1.20.0
Server Version: v1.19.6

错误信息

error validating data: [ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "serviceName" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "servicePort" in io.k8s.api.networking.v1.IngressBackend]; if you choose to ignore these errors, turn validation off with --validate=false

【解决方案1】：

请在下面找到 1.19 Kubernetes 版本的示例入口

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: minimal-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /testpath
        pathType: Prefix
        backend:
          service:
            name: test
            port:
              number: 80

如果您运行的是 Kubernetes 版本 1.18

示例入口将类似于

apiVersion: "networking.k8s.io/v1beta1"
kind: "Ingress"
metadata:
  name: "example-ingress"
spec:
  ingressClassName: "external-lb"
  rules:
  - host: "*.example.com"
    http:
      paths:
      - path: "/example"
        pathType: "Prefix"
        backend:
          serviceName: "example-service"
          servicePort: 80
