CloudFlare-Ploi-Dynamic-IP

This script updates the DNS records for a given domain hosted on CloudFlare and communicates with Ploi's API. It requires your system to have curl, jq and dig installed.

Prerequisites and Setup

• Make sure to install curl, jq and dig tool in your system.
• Update the PLOI_SERVER_ID and PLOI_API_KEY with your Ploi server ID and API key respectively.
• Update CF_API_KEY and CF_ZONE_ID with your Cloudflare API key and Zone ID respectively.
• Set your domain in the DOMAIN variable.
• The INTERVAL value represents how often (in minutes) the script checks if your DNS needs an update.

How it works

• The script first requests your current public IP address from the OpenDNS resolver.
• The script then fetches the existing DNS records for the given domain from Cloudflare's API.
• If the public IP differs from the IP in the A record, then the script sends an API request to Cloudflare to update the A record with the current public IP.
• If the DNS record name matches the domain, the script will also send an update request to Ploi's API.

Filter

• The script has defined a filter to list the CloudFlare DNS Records @,*
• Set your custom subdomains here accordingly, the only one required is @
• If you want to add test.domain.com you only need to add test to the filter eg. filter("@" "test")

Docker Containers

• The script also checks for running Docker containers with an environment variable VIRTUAL_HOST.
• If found, it will add the name of the container to the domain list for updating.

Advanced usage

• It is recommended to start this script at startup by adding it to the cron job for automatic updates.
• To add a cron job, open your cron tab with crontab -e and add the line @reboot /path/to/dynamic-ip-full.sh &.

Note: Be sure to replace /path/to/dynamic-ip-full.sh with the actual path to your script.
