API 的 AKS 入口

Question

我正在尝试部署一个 ASP-Net Core API 并通过入口使其从集群外部可用。 我已按照学习页面中提到的步骤进行操作。 所有步骤都运行良好，但是，我无法访问路由 /api/opportunities/ 上的入口。 下面我描述了我的 K8S 文件，我可能遗漏了什么？

apiVersion: apps/v1
kind: Deployment
metadata:
  name: opportunities-api
spec:
  replicas: 1
  selector:
    matchLabels:
      component: opportunities-api
  template:
    metadata:
      labels:
        component: opportunities-api
    spec:
      containers:
        - name: opportunities-api
          image: mycontainer.azurecr.io/opportunities-api:{BUILD_NO}
          imagePullPolicy: Always
          ports:
            - containerPort: 80

apiVersion: v1
kind: Service
metadata:  
  name: opportunities-api  
spec:
  ports:
  - port : 80
    protocol: TCP
    targetPort: 80
  selector:
    component: opportunities-api
  type: ClusterIP

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: opportunities-api
  annotations:
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /api(/|$)(.*)
        pathType: Prefix
        backend:
          service:
            name: opportunities-api
            port:
              number: 80

我看到上面的入口 yaml 中缺少主机字段。您是否尝试在入口 yaml 中添加.spec.rules.host ，如下所示，看看是否有帮助？ 根据 nginx 文档，它是限制之一。

此外，如果 AKS v>=1.24，那么您可以检查在入口 controller 服务中为注释service.beta.kube.netes.io/azure-load-balancer-health-probe-request-path设置的值是多少。 它应该是/healthz如AKS Ingress-Nginx ingress controller failing to route by host中所讨论的

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: opportunities-api
  annotations:
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  ingressClassName: nginx
  rules:
  - host: abc.com #your host name here
    http:
      paths:
      - path: /api(/|$)(.*)
        pathType: Prefix
        backend:
          service:
            name: opportunities-api
            port:
              number: 80
