<p>Suppose, I have several Kubernetes clusters and I have some namespaces in each of them.</p>
<p>Some of these namespaces are labeled <code>project: a</code> and others <code>project: b</code>.</p>
<p>Now I want to ensure that resources in namespaces labeled <code>project: a</code> can communicate with each other, but not with something else, same for the other projects.</p>
<p>If it was just one Kubernetes cluster, then I would simply use NetworkPolicies.</p>
<p>However, I would like to connect the clusters somehow and to ensure that this restriction applies also when the resources are spread in many clusters.</p>

<p>Network policies are bound to the local cluster and don't work across clusters for now.</p>
