Tony,
sorry for the delay.
You cannot list all pods. So you need to list on a namespace:
List<IPod> pods = client.list(ResourceKind.*POD*, namespace);
for(Pod pod : pods) {
pod.getLabels().get("*service_owner*") gives you the SERVICE_OWNER label
and so on for your specific labels
Please use the mailing list [email protected] to contact
OpenShift devs from now
