Basic Kubernetes Service Hello World Example: Issue Exposing Service using LoadBalancer

[Traiano Welcome]

Hi All

I'm going through this kubernetes hello world tutorial and just trying to expose a basic nginx service via LoadBalancer:

http://janetkuo.github.io/docs/hellonode/

I spin up a service as follows:

 bash-3.2$ kubectl run hello-node --image=nginx --port=80
 deployment "hello-node" created

--

bash-3.2$ kubectl get deployments
NAME         DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
hello-node   1         1     

--

bash-3.2$ kubectl get pods
NAME                          READY     STATUS    RESTARTS   AGE
hello-node-4180085773-f4p9x   1/1       Running   0          43s

--

kubectl get events:

---

9m        9m        1         hello-node-4180085773-f4p9x   Pod          spec.containers{hello-node}   Normal    Created             kubelet, kubernetes-minion-group-kmg7   Created container with id 3caeab9ebdc3445811d09537d59f4449ec51b1d22d08221577a239352929c128

---

I then try to expose the service to the general internet via loadbalancer mechanism it appears to accept the request, but stays in pending forever:

bash-3.2$ date;kubectl get services hello-node
Tue May 23 14:17:56 +04 2017
NAME         CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
hello-node   10.0.241.214   <pending>     80:31715/TCP   13m

bash-3.2$
bash-3.2$ date;kubectl get services hello-node
Tue May 23 14:18:39 +04 2017
NAME         CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
hello-node   10.0.241.214   <pending>     80:31715/TCP   14m
bash-3.2$

bash-3.2$
bash-3.2$ date;kubectl get services hello-node
Tue May 23 14:52:43 +04 2017
NAME         CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
hello-node   10.0.241.214   <pending>     80:31715/TCP   48m

My question is: How do I troubleshoot this further,and hopefully fix it?

Thanks,
Traiano

Hi Traiano,

I am copying  the kubernetes-users list where your question should be posted.

You can also try stackoverflow, these will be better channels as we try to get all users questions in the same place.

thanks a lot

Please re-post your question to [stackoverflow]
(http://stackoverflow.com/questions/tagged/kubernetes).

We are trying to consolidate the channels to which questions for help/support
are posted so that we can improve our efficiency in responding to your requests,
and to make it easier for you to find answers to frequently asked questions and
how to address common use cases.

We regularly see messages posted in multiple forums, with the full response
thread only in one place or, worse, spread across multiple forums. Also, the
large volume of support issues on github is making it difficult for us to use
issues to identify real bugs.

The Kubernetes team scans stackoverflow on a regular basis, and will try to
ensure your questions don't go unanswered.

Before posting a new question, please search stackoverflow for answers to
similar questions, and also familiarize yourself with:

  * [user documentation](http://kubernetes.io/docs/)
  * [troubleshooting guide](https://kubernetes.io/docs/tasks/debug-application-cluster/troubleshooting/)

Again, thanks for using Kubernetes.

The Kubernetes Team
