- Nameserver holds a sorted list of (hostname, peer, container id, ip) tuples. - Entries are gossiped using topology gossip / broadcast - only new/updated entries are propogated as expected. - Entries for a given peer are removed when the connection to the peer is lost. - Entries are tombstoned when containers die. Tombstones are kept for 10mins, as they do not need to survive partition, only gossip propagation delay.
