Subject Re: Multi-region Kubernetes service un-deployment
Date Sat, 19 Sep 2015 16:00:20 GMT
I had an offline discussion on this with Gayan. It looks like the root
cause of this problem is that we have added Kubernetes Cluster ID to the
Cluster Context. This seems to be incorrect. A cluster can have multiple
Kubernetes Clusters if its a multi-region deployment.

We need to remove the property ClusterContext.kubernetesClsuterId() and do
following to find the Kubernetes Cluster ID of a member:

Partition partition = memberContext.getPartition();

String kubernetesClusterId = partition.getKubernetesClusterId();

KubernetesCluster kubernetesCluster =
CloudControllerContext.getInstance().getKubernetesCluster(kubernetesClusterId);


In addition we also identified few improvements that we can do in
KubernetesIaas class. Gayan is now working on this fix.

Thanks
