Dynamic updates between instances

[cortjehster]

I have two dockerized instances running DNS and DHCP. The first is primary for DNS and DHCP and dynamic updates for forward and reverse work just fine. The secondary gets zone transfers from the primary and has a delay on DHCP. Even with the delay, however, it still ends up handing out DHCP addresses from time to time. When it does, it does not do DNS updates to the primary. To simplify it as much as possible, I've permitted updates from anywhere on the primary and not enforced any TSIG. I'm guessing I've missed something, but I can't figure out what.

Does anyone have any suggestions?

Thanks for asking. DHCP server currently can only update the same instance its running on. DDNS is not yet supported by DHCP server.

Clients getting lease assigned by the secondary DHCP is really a client side issue where for some reason, the client did not select the offer from the primary DHCP server and accepted the delayed offer from secondary DHCP.

There is clustering feature planned for DHCP server which will do this automatically. It is planned to be implemented once clustering for DNS features is available.

Thanks for the response. I look forward to the clustering feature when it comes out!
