azure - AKS - 将插件 HTTP 应用程序路由与 nginx 重写规则结合起来？

Question

我正在使用 Azure AKS 插件进行 HTTP 应用程序路由，如 here 中所述。我使用 Terraform 部署了它，它通常可以工作:

resource "kubernetes_ingress" "ingress" {
  metadata {
    name      = "nurse-ingress"
    namespace = kubernetes_namespace.nurse.metadata[0].name
    annotations = {
      "kubernetes.io/ingress.class" = "addon-http-application-routing"
      "nginx.ingress.kubernetes.io/rewrite-target" = "/$1"
    }
  }

  wait_for_load_balancer = true

  spec {
    backend {
      service_name = "nurse-service"
      service_port = 80
    }

    rule {
      host = "nurseapp.${azurerm_kubernetes_cluster.main.addon_profile[0].http_application_routing[0].http_application_routing_zone_name}"
      http {
        path {
          backend {
            service_name = kubernetes_service.app.metadata[0].name
            service_port = 80
          }

          path = "/app/(.*)"
        }

        path {
          backend {
            service_name = kubernetes_service.nurse.metadata[0].name
            service_port = 80
          }

          path = "/nurse/(.*)"
        }
      }
    }
  }
}

但是，它仅适用于默认后端(即path=/)。当我在/nurse 或/app 上调用 URL 时，它不起作用，因为重写目标 /$1 似乎没有被考虑在内。我只会收到 404 - 因为护士服务本身确实期望调用/foo 而不是/nurse/foo

这是否可以开始配置，如果可以，知道我的错误在哪里吗？

以下内容将重写路径，以便对 /sample/suffix 的请求将被重写为 /suffix:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: sample-ingress
  annotations:
    kubernetes.io/ingress.class: addon-http-application-routing
    nginx.ingress.kubernetes.io/rewrite-target: $2
spec:
  rules:
  - host: sample.YOUR-ID.westeurope.aksapp.io
    http:
      paths:
      - path: /sample/
        pathType: Prefix
        backend:
          service:
            name: sample
            port:
              number: 80
