I'm trying to make a pi-hole container listen only on one of my server's IPs (I have multiple netowrk cards), the other one is forwarded through the firewall, but I need to listen to port 53 (UDP & TCP), so I'm basically facing this problem:
pihole:
...
ports:
- "10.1.0.5:53:53/udp" # this will not work
- "10.1.0.5:53:53/tcp"
...
I've checked Docker's published ports documentation, and it appears that ports can only specify either an IP to bind to, OR a protocol, not both, for some reason. Is there another way to do this? Am I missing something? Did I miss-read the docs?
Nevermind, apparently it was something else that was failing, I am not sure what exactly, but the code in my question is correct. I'll leave this up in case anybody else is wondering how to do this, this is my docker-compose's ports section:
