I follow this docs https://cloud.google.com/container-engine/docs/tutorials/guestbook to created a Guestbook on GCE. And everything works fine.

But when I try to access kube-ui. I am totally confused.

first

≥ kubectl get svc                                                                                                                        14:29
NAME           LABELS                                    SELECTOR            IP(S)            PORT(S)
frontend       name=frontend                             name=frontend       10.191.254.236   80/TCP
                                                                             146.148.x.x    
kubernetes     component=apiserver,provider=kubernetes   <none>              10.191.240.1     443/TCP
redis-master   name=redis-master                         name=redis-master   10.191.253.125   6379/TCP
redis-slave    name=redis-slave                          name=redis-slave    10.191.254.248   6379/TCP

I can access my guestbook by 146.148.x.x; But I can't access web-ui through this ip. So I think this is not the master IP of my GCE. Then I execute this:

≥ kubectl get endpoints                                                                                                                  14:33
NAME           ENDPOINTS
frontend       10.188.0.6:80,10.188.0.7:80,10.188.2.4:80 + 2 more...
kubernetes     104.197.x.x:443
redis-master   10.188.2.7:6379
redis-slave    10.188.0.8:6379,10.188.2.3:6379

Now, I got another IP, and I try to access kube-ui through this IP. I can get response from the server. But It will need Authtication.

How can I get access to the kube-ui?

Never mind, I got it

gcloud container clusters describe CLUSTER-NAME

contains username and password!

The 146.148.x.x IP listed under "frontend" service is there because of this entry in the service spec:

"type": "LoadBalancer"

It allows your application to be access externally.

Another useful command is

kubectl cluster-info

Also it can be checked out for detailed kubelctl config in following 2 ways:

  • client config file - ~/.kube/config

  • Develop Console - [GCP project]/[GCE instance], show in table of Custom meta data, kube-env row
