Latest Docker image now saying my DNS upstream IP isn't valid

Help docker
1

Hi,

I've recently updated my pi-hole docker container image and now when the container tries to start it now says Invalid IP detected in PIHOLE_DNS_: "192.168.2.1#15353", I haven't changed this config in a good while, and according to the docs it is indeed a valid value. Which leads too the docker container to keep restarting.

Any ideas why this is happening?

Docker compose file

version: "2"

services:
  pi-hole:
    container_name: pi-hole
    hostname: pi-hole.docker
    restart: always
    image: pihole/pihole:latest
    dns:
      - 192.168.2.1
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "80:80/tcp"
    environment:
      - TZ=Europe/London
      - VIRTUAL_HOST=pi-hole.lynx
      - PIHOLE_DNS_="192.168.2.1#15353"
    volumes:
      - /docker/pi-hole/pihole/:/etc/pihole/
      - '/docker/pi-hole/dnsmasq.d:/etc/dnsmasq.d/'

Many Thanks

I've worked out the issue.

Changing - PIHOLE_DNS_="192.168.2.1#15353" to - PIHOLE_DNS_=192.168.2.1#15353 fixed the issue. Although this has been working for a long time, clearly wasn't required but also something has changed to make it not work.
