my pihole is running via portainer on a raspberry pi 4. even when I ssh into the container, I get a resolution error:
```auto
sudo docker exec -it pihole /bin/bash
sudo: unable to resolve host pitron: Name or service not known
root@pihole:/#
```
but I can then attach successfully to the container.
this is the output of pihole -debug: [gist:91e673652558ba0fef198a9f9f9b029a · GitHub](https://gist.github.com/plc/91e673652558ba0fef198a9f9f9b029a)
it says:
`172.17.0.3/16 does not match the IP found in /etc/pihole/setupVars.conf`
in that file it says:
`IPV4_ADDRESS=0.0.0.0`
and whenever I update it with 172.17.0.3 it gets overwritten back to 0.0.0.0?
if I run dig ns1.pi-hole.net:
```auto
root@pihole:/# dig ns1.pi-hole.net
;; reply from unexpected source: 172.17.0.1#53, expected 192.168.7.8#53
```
and yet using @8.8.8.8 works fine:
```auto
root@pihole:/# dig ns1.pi-hole.net @8.8.8.8
; <<>> DiG 9.10.3-P4-Debian <<>> ns1.pi-hole.net @8.8.8.8

any help would be much appreciated!!! 😭

(_For your own privacy and security, please do not post your full, unsanitised debug log output. When providing a debug token, please post **just the token** that is shown once the debug finishes, preferably by copy and paste._)
Your issues are likely related to correctly configuring [Docker's network driver](https://docs.docker.com/network/).
Also, you are trying to tamper with the Docker image in ways not advisable, e.g. by running updates on your Pi-hole or its OS from within the container:
```auto
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
root@pihole:/# sudo !!
sudo apt-get update
```
Note that any such changes you apply to a container would not survive a container restart.
In addition, you seem to have altered some of Pi-hole's default web server's configurations:
```auto
*** [DIAGNOSING]: contents of /etc/lighttpd
-rw-r--r-- 1 root root 4066 Oct 5 03:57 /etc/lighttpd/lighttpd.conf
include_shell "/usr/share/lighttpd/use-ipv6.pl " + server.port
include_shell "find /etc/lighttpd/conf-enabled -name '*.conf' -a ! -name 'letsencrypt.conf' -printf 'include \"%p\"' 2>/dev/null"
```
I doesn't seem you are using Pi-hole's [official Docker](https://github.com/pi-hole/docker-pi-hole#docker-pi-hole) image at all?

That's a warning from `sudo`, it doesn't actually stop or break anything. `sudo` tries to look up the host name since you can have per host `sudo` rules. Easy solution to that is to put `pitron` in your `/etc/hosts` file with localhost as the address.
