Bind does not have a method to do multi-master replication. All updates must

In our case, we've used containers and Consul for providing a highly available
DNS service. A container will fire up and race for the master lock. It will
dump the contents of the database into its named configurations and assuming it
has the lock will assume the IP address of the master. Others just come up as
slaves.
If the master lock is not renewed after a given period of time another
container can acquire the lock and become master by assuming the IP address of
master (VRRP/VRID/KeepAliveD)
Hi James,
Do you have any more info on this setup? I'm in the middle of looking at
changing our DNS service and was thinking of containerising them for the
improved deployment flexibility it offers.
