Re: questions about externalIP usage

[Yu Wei]

Hi Erik,

I configured "externalIPs" with cluster setup using flannel but it didn't work.

Then I reinstalled cluster with openvswitch. This time "externalIP" worked.


Is openvwitch suggested network plugin for openshift origin?

I deployed same application in k8s cluster and it worked.


Thanks,

Hi Jared,

Did you previously configure the cluster for externalip usage?

Hi guys,

I deployed redis with replication controller successfully on openshift origin 
cluster.

Then I tried to create service for external clients to connect.

However, it seemed that it didn't work.

How could I debug similar problem? Is there any guidance about using externalIP 
in openshift?


The detailed information is as below,
