                      Cluster peering is the recommended way to connect services across or within Consul datacenters. Peering is a one-to-one relationship in which each peer is either a open-source Consul datacenter or a Consul enterprise admin partition. There don't seem to be any peers for this {{if (can "use partitions") "admin partition" "datacenter"}}, or you may not have the <code>peering:read</code> permissions to access this view.
