Join Projects to a PodNetwork

Issue

• We are running our Openshift-Cluster with the multitenant-network-plugin in order to be able to reach services across projects we have joined certain projects to a Pod-Network (oadm pod-network join-projects --to=) Is there a possibility to list all of the Projects who are in a existing pod-network? (let's say someone is asking 6 months after the cluster-admin has joined the projects)

• If we have to add a second projects to this pod-network i guess we have to list all of the projects PLUS the new one, right?
