Docker containers DNS lookups fails?

[antgustech]

Couple of weeks ago deployed Adguard docker container on my home server and configured my router to point at it. It seemed to work just fine, clients get the DNS and Adguardhome is dealing with the reqests as exptected. However, it seems that my other docker containers DNS lookup fails entirely. For example I use Watchtower to update my containers, upon startup it gives me the following error:
watchtower | time="2024-04-13T20:32:50+02:00" level=error msg="Failed to send shoutrrr notification" error="error getting SMTP client: error connecting to server: dial tcp: lookup smtp.gmail.com on 127.0.0.11:53: server misbehaving" index=0 notify=no service=smtp

On my server, checking the dns, it seems to point at the correct adress:

cat /etc/resolv.conf
nameserver 192.168.1.142

And I can see in adguard that requests are indeed made to smtp.gmail.com and are not blocked.

So what do I do here?

I found the solution here:
#6252

Add:

  - "192.168.1.142:53:53/tcp"
  - "192.168.1.142:53:53/udp"
  - "[::]:53:53"
