Interface eth0 does not currently exist

Help docker

Hello everyone
my current setup is this:

  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    environment:
      TZ: 'Europe/Rome'
      WEBPASSWORD: 'yaddayadda'
      PIHOLE_DNS_: 1.1.1.1;1.0.0.1
      DHCP_ACTIVE: "true"
      DHCP_START: 192.168.1.3
      DHCP_END: 192.168.1.254
      DHCP_ROUTER: 192.168.1.1
      DHCP_LEASETIME: 1
      PIHOLE_DOMAIN: lan
    network_mode: host
    volumes:
      - "./etc-pihole:/etc/pihole"
      - "./etc-dnsmasq.d:/etc/dnsmasq.d"
      #   https://github.com/pi-hole/docker-pi-hole#note-on-capabilities
    cap_add:
      - "NET_ADMIN"
      # Required if you are using Pi-hole as your DHCP server, else not needed
    restart: unless-stopped

but when I go in the admin dashboard's "Pi-hole diagnosis" I get this warning interface eth0 does not currently exist.

The only solution I could look up to in this forum was something related to setting DELAY_STARTUP pihole-FTL.conf but it doesn't work for me.

The workaround I'm using now is appending interface=enp3s0 in 01-pihole.conf and making it immutable with chattr +i since it gets rewritten upon container's restart.

Any suggestion about how to solve this issue?

Set Pi-hole's INTERFACE advanced environment variable for your Docker container, and/or adjust DNSMASQ_LISTENING.

Thanks! I don't know how I missed that
