Cloudflare Tunnel DNS Record Creation Script

This project contains a bash script for creating DNS records in Cloudflare and pointing to a specified Cloudflare Tunnel. The script parses the Bunnyshell env definition file (passed in as $COMPONENTS) to extract the list or DNS records to be created. Next, the script interacts with the Cloudflare API to create DNS records.

Prerequisites

• Bash
• jq
• curl

Environment Variables

The script requires the following environment variables:

• COMPONENTS: The Bunnyshell yaml env configuration, generated like this: COMPONENTS: '{{ component.name}}|{{ components|json_encode }}' .
• CF_ACCOUNT_ID: Your Cloudflare account ID.
• CF_TUNNEL_ID: The ID of the Cloudflare tunnel.
• CF_ZONE_ID: The ID of the Cloudflare zone.
• one of two ways of authentication:
  • CF_API_KEY and CF_EMAIL: Your (Global) Cloudflare API key.
  • of CF_API_TOKEN: a CF API token with necessary permissions: read account settings, read Tunnel settings and edit zone.

Usage

To run the script, simply execute the create_records.sh file in your terminal/pipeline:

./create_records.sh

The script will print out the DNS records that need to be created, retrieve the initial settings from Cloudflare, and then create a record for each URL in the list. If a URL matches the pattern bunnyenv.com, it will be skipped.
