kubernetes - GCE Ingress 未从就绪探针中获取健康检查

Question

当我创建 GCE 入口时，Google 负载均衡器不会从就绪探针设置运行状况检查。根据文档( Ingress GCE health checks )它应该捡起来。

Expose an arbitrary URL as a readiness probe on the pods backing the Service.

任何想法为什么？

显然，您需要在 PodSpec 上包含容器端口。
似乎没有任何地方记录。

例如

    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80
