GCE Ingress无法从准备就绪调查中获取健康检查 [英] GCE Ingress not picking up health check from readiness probe

问题描述

当我创建GCE入口时，Google Load Balancer不会通过就绪探针设置运行状况检查.根据文档( Ingress GCE健康检查)，它应该进行检查. /p>

When I create a GCE ingress, Google Load Balancer does not set the health check from the readiness probe. According to the docs (Ingress GCE health checks) it should pick it up.

在支持服务的Pod上公开一个任意URL，作为准备情况调查.

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

有什么想法吗?

推荐答案

因此，显然，您需要在PodSpec上包括容器端口. 似乎没有记录在任何地方.

So apparently, you need to include the container port on the PodSpec. Does not seem to be documented anywhere.

例如

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