resolv.conf nameserver is set to 127.0.0.11

Versions

Pi-hole version is v5.17.2 (Latest: v5.17.2) web version is v5.21 (Latest: v5.21) FTL version is v5.23 (Latest: v5.23) Container tag is: 2023.11.0

Platform

• OS and version: Raspbian 11 and Arch Linux

• Platform: Raspberry Pi 3, x86
• Docker: 24.0.5 / 24.0.7

Expected behavior

When starting up the latest docker image via docker compose, the container manages to connect to the host dns server.

Actual behavior / bug

For some reason /etc/resolv.conf has the name server set to 127.0.0.11 instead of 127.0.0.1, therefore pi hole can not update it's local ad lists. I do not know where this problem comes from, but i've been able to work around it making a volume of the resolv.conf without the extra 1

Steps to reproduce

Steps to reproduce the behavior:

take an example docker-compose.yml and run docker compose up --detach

Additional context

none

I found no editor inside the docker image, so I used "echo" to change the file. First have a look into the current settings: cat /etc/resolv.conf

Note the existing content of the file and alter the wrong line. In my case this is: echo "nameserver 127.0.0.1" > /etc/resolv.conf echo "options ndots:0" >> /etc/resolv.conf

Yes, I know, this is not a solution, just a workaround.

For some reason /etc/resolv.conf has the name server set to 127.0.0.11 instead of 127.0.0.1

All containers here are using 127.0.0.11 (docker DNS) without issues.

In your compose file, put something like

dns: 8.8.8.8

Or whatever DNS you want the container to use

No need to edit the resolv.conf

[RABijl]

Ah so the container should be set with a DNS server it will use. Is this required by default? If so, maybe the example could be updated to reflect this.

Sorry, but I don't understand why not FIX a clear problem with an easy change, instead of using a workaround?
