我在 Kubernetes AKS 上安装了 HA 代理入口。我安装它使用：

helm install ingress haproxy-ingress/haproxy-ingress

我的入口是这样的：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress  
metadata:
  name: ravendb
  namespace: default
  labels:
    app: ravendb
  annotations:
    ingress.kubernetes.io/ssl-passthrough: "true"
spec:
  rules:
  - host: a.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-0
          servicePort: 443
        path: /
  - host: tcp-a.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-0
          servicePort: 38888
        path: /
  - host: b.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-1
          servicePort: 443
        path: /
  - host: tcp-b.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-1
          servicePort: 38888
        path: /
  - host: c.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-2
          servicePort: 443
        path: /
  - host: tcp-c.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-2
          servicePort: 38888
        path: /

但是，当我将浏览器指向https://a.raven.aedas-prev.inercya.com时，我得到了默认后端。HA 代理不会将请求反向代理到 ravendb-0 服务。

我做错了什么？我该怎么做才能使入口工作？

Pod 正在运行：

并配置服务：

我终于弄清楚我错过了什么。我添加了kubernetes.io/ingress.class: haproxy注释并解决了问题：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress  
metadata:
  name: ravendb
  namespace: default
  labels:
    app: ravendb
  annotations:
    ingress.kubernetes.io/ssl-passthrough: "true"
    kubernetes.io/ingress.class: haproxy
spec:
  rules:
  - host: a.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-0
          servicePort: 443
        path: /
  - host: tcp-a.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-0
          servicePort: 38888
        path: /
  - host: b.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-1
          servicePort: 443
        path: /
  - host: tcp-b.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-1
          servicePort: 38888
        path: /
  - host: c.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-2
          servicePort: 443
        path: /
  - host: tcp-c.raven.aedas-prev.inercya.com
    http:
      paths:
      - backend:
          serviceName: ravendb-2
          servicePort: 38888
        path: /

现在 HAproxy 入口按预期工作，将外部流量反向代理到内部服务。
