Cloudflare ☁️ Dynamic DNS IP Updater

This tool allow you to have a specific DNS record such as home.example.com that point to your home IP

Use Case

I suggest you to install it on a Raspberry Pi!🍓

Requirements

• Domain Name
• Cloudflare Account
• Raspberry Pi4 or any other Linux Based OS
• composer
• php-7.3

Installation

git clone https://github.com/andp97/cloudflare-dynamic-ip.git
cd cloudflare-dynamic-ip
INSTALL_PATH=$(pwd)
composer install --no-dev
nano .env
echo -e "*/15 * * * * $INSTALL_PATH/cf-ip 2>&1 > /dev/null\n"
crontab -e

You can also execute this script via bash

#Get dns record name from env and target ip from remote host (https://ip.andreapavone.com) 
./cf-ip
#Passing parameters to the script
./cf-ip <dns_record_name> <target_ip>

On .env file you can set:

• CLOUDFLARE_TOKEN (see how can you generate token here: https://support.cloudflare.com/hc/en-us/articles/200167836-Managing-API-Tokens-and-Keys)
• CLOUDFLARE_ZONE_NAME or CLOUDFLARE_ZONE_ID
• DNS_RECORD_NAME is the subdomain that you prefer to use (for example: home.example.com). If you prefer to be safer use a randomized token for the DNS_RECORD_NAME

Update

composer update
