network.routed_bridge

addr

scopable True
required False
default Detect using a name resolution of <nodename>. Beware, if the nodename resolves to 127.0.1.1 or 127.0.0.1 the ipip tunnel can not work.
scope order specific > generic

The ip address used as local endpoint for the ipip tunnel configured by network setup to access the backend subnet of peer nodes not on the same subnet.

ips_per_node

scopable False
required False
default 1024
scope order specific > generic
convert integer

network

scopable False
required False
default 10.22.0.0/16
scope order specific > generic

The cluster backend network. The routed_bridge driver fragments this network into <ips_per_nodes> blocks> subnets.

subnet

scopable False
required False
default 10.22.0.0/16
scope order specific > generic

The cluster backend network to fragment for nodes into <ips_per_nodes> blocks.

tunnel

scopable False
required False
default auto
scope order specific > generic
candidates auto | always

Create and route trafic through tunnels to peer nodes policy. auto: tunnel if the peer is not in the same subnet, always: tunnel even if the peer seems to be in the same subnet (some hosting providers require this as traffic goes through router even between adjacent nodes.
