Does someone know if there is a big overhead in bandwidth in the Rancher IPsec managed network to keeping communication established or talking with containers?
I understand Rancher creates a tunnel for inter network communication between hosts but I’m a bit concerned about the bandwidth for remote hosts. If there is no data transferred between clustered containers what kind of data is constantly send for Rancher to maintain communication/stats between all systems?
Is this something that can properly scale as well as you keep adding hosts Rancher+Cattle?
