[infinispan-dev] Unable to cluster Infinispan ephemeral template instances

[Sebastian Laskawiec]

Seems like you didn't fill the namespace parameter while creating an app:
https://github.com/infinispan/infinispan-openshift-templates/blob/master/templates/infinispan-ephemeral.json#L336

I already tried to eliminate this parameter (because it seems redundant)
but currently there is no way to do it [1]. It s required for Role Binding
which enables the Pod to query Kubernetes API and ask about Pods [2].

You may also try to use the third way:
oc policy add-role-to-user view system:serviceaccount:<<your
namespace>>:<<service account used for Deployment Config>>
