Hi,

But I don't want to specify a node name in my reques= t because I don't bother wherever they run in the cluster but all of th= em have to be on the same node. Is there a way to make such a request for c= ontainers currently? Or if not, I think this would be good to be have becau= se many applications could have such kind of requirement.
