Question

Hello Kubernetes Gurus，

我刚刚在Centos7上设置了我自己的BareBone cluser，有1个主/ 2个节点。我目前正在阅读GuestBook教程，当我认为一切运行顺利时，我遇到了阻止程序...我无法访问GuestBook网页，因为“kubectl get services”或“kubectl describe services / frontend”isn'给我一个“ExternalIP”。事实上，它根本没有向我显示“ExternalIP”栏目。

我是否错误地设置了它？如何从外部访问我的留言簿？

提前感谢您的知识匮乏。

以下是我的配置/获取：

frontend-service.yaml:

apiVersion: v1
kind: Service
metadata:
  name: frontend
  labels:
    name: frontend
spec:
  # if your cluster supports it, uncomment the following to automatically create
  # an external load-balanced IP for the frontend service.
  type: LoadBalancer
  ports:
    # the port that this service should serve on
    - port: 80
  selector:
    name: frontend

kubectl version:
    Client Version: version.Info{Major:"1", Minor:"1+", GitVersion:"v1.1.0-alpha.0.1464+2bfa9a1f98147c",         GitCommit:"2bfa9a1f98147cfdc2e9f4cf50e2c430518d91eb", GitTreeState:"clean"}

Kubernetes通过与云提供商API集成来分配外部IP。如果您运行的是“裸机”群集或任何不是集成云提供商的群集，则需要手动分配外部IP，如services documentation中所述。

“kubectl get services”未显示“ExternalIP”列
