使用Google的外部HTTP负载均衡器将外部服务连接到GCP GKE Kubernetes集群

Question

我正在尝试将一个外部网页流页面连接到我们在GCP GKE上的kubernetes集群入口。具体地说，我希望www.domain.com上的所有内容都转到外部webflow服务上，而www.domain.com/app上的所有内容都转到集群中的本地服务上。

我已经看到了这个问题Ingress Nginx Proxy to Outside Website (Webflow hosted)，并跟踪了它，但我不能让它工作。我一直收到一个错误的Translation failed: invalid ingress spec: service "default/external-service" is type "ExternalName", expected "NodePort" or "LoadBalancer"; service "default/external-service" is type "ExternalName", expected "NodePort" or "LoadBalancer"

这是我的设置

外部服务：

apiVersion: v1
kind: Service
metadata:
  name: external-service
  namespace: default
spec:
  externalName: participant-homepage-9f8712.webflow.io
  ports:
  - port: 443
    protocol: TCP
    targetPort: 443
  sessionAffinity: None
  type: ExternalName
status:
  loadBalancer: {}

入口：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    ingress.gcp.kubernetes.io/pre-shared-cert: _,
    ingress.kubernetes.io/backends: _,

      - backend:
          serviceName: app-service
          servicePort: 80
        path: /app/*
        pathType: ImplementationSpecific
      - backend:

        path: /*

    ingress:

任何帮助都将不胜感激。谢谢!

为什么你引用的Ingress Nginx Proxy to Outside Website (Webflow hosted)问题的步骤不起作用，是因为这个问题关注的是EKS (亚马逊弹性Kubernetes服务)。GCE Ingress不支持ExternalName服务，您可以在以下question中看到这一点。我向您推荐的是将其作为功能请求发布在Google's Issue tracker上
