One comment to add:
It would be particularly useful if the interface used to set the
topology is something sane that a single host can use to set its
peers. Eg:
host1$ ipa-topology-set-peers host2
host2$ ipa-topology-set-peers host3
host3$ ipa-topology-set-peers host4
host4$ ipa-topology-set-peers host1 # redundant, but okay...
This way config management could define topologies in terms of algorithms. Eg:
Ring topology:
Order hostnames alphabetically.
Peer with host name index of self + 1
(Example shown above)
Star topology:
Peer with every other host in list
Pick two topology:
Peer with each subsequent hosts in ordered list...
And so on...
If running the command changes the topology again, then that's great
because changing the algorithm would re-arrange the graph :)
Hope this made sense.
Cheers,
James
