[Pdns-users] Master/Slaves in docker containers

[Christian Tardif]

Hi,

I'm trying to get this to work:

I have one master pdns in a docker container with bridge networking on 1 
server, plus a slave pdns, also in a docker container with bridge 
networking on another server. On the master, I have a zone (until I get 
it to work) configured as I would do with any other dns servers (SOA, NS 
records (with the real IP of the master and slaves, as I need to reach 
them from this "external" ip).

When I'm doing an update on the zone in the master, I see that, on the 
slave server, that I'm receiving the NOTIFY, but coming from 172.17.0.1 
(got from the docker bridge) but then, the slave tries to get either the 
SOA on NS records for the zone....  at 172.17.0.1, which leads to 
nothing, as this is a NAT.   How can I have the slave to unconditionally 
request the master server (on its real IP) for this zone about the SOA 
so this master/slave setup actually works?

On a different note, I'm not sure to undersand really how superserver 
works (not sure my setup's working, anyway, as the logs on the slave 
keep telling that:

Received NOTIFY for .......  from 172.17.0.1 for which we are not 
authoritative. I would've expect the slave to configure automatically 
from the master. Something must be missing on my setup...

Thanks,
