Have pihole running and pointed to cloudflare under DNS but no traffic seen under cloudflare page analytics. 

on FWG, nslookup resolves my domain to my WAN IP

Went through configuration as follows:

Registered new domain on cloudflare and configured to A record for both www, and ****.com pointed to my WAN IP. 

configured docker container .yaml file with the below: 
(this docker network is different than my pihole docker network) 

 

version: '2'
services:
  cloudflare-ddns:
    image: oznu/cloudflare-ddns:latest
    restart: always
    container_name: cloudflareddns
    environment:
      - API_KEY=****
      - ZONE=****.com
      - PROXIED=false
networks:
  default:
    driver: bridge
    ipam:
     config:
       # your chosen docker network here
       - subnet: 172.15.0.0/30
 

 

Started:     

cd /home/pi/.firewalla/run/docker/cloudflareddns
sudo systemctl start docker
sudo docker-compose pull
sudo docker-compose up --no-start
sudo ip route add 172.15.0.0/30 dev br-$(sudo docker network inspect cloudflareddns_default |jq -r '.[0].Id[0:12]') table wan_routable
sudo docker-compose up --detach

Persistance .sh:

sudo systemctl start docker
sudo systemctl start docker-compose@cloudflareddns
sudo ipset create -! docker_wan_routable_net_set hash:net
sudo ipset add -! docker_wan_routable_net_set 172.15.0.0/30

  As soon as i put in my DNS entries in compose, my ip was updated on cloudflare to reflect my actual WAN ip. 

   

  version: '2'
  services:
    cloudflare-ddns:
      image: oznu/cloudflare-ddns:latest
      restart: always
      container_name: cloudflareddns
      environment:
        - API_KEY=****
        - ZONE=****
        - PROXIED=true
      dns:
        - 172.16.0.2 (pihole)
        - 127.0.0.1
  networks:
    default:
      driver: bridge
      ipam:
       config:
         # your chosen docker network here
         - subnet: 172.15.0.0/24
