Google Cloud Function - ifconfig

Queries http://ifconfig.co from GCF to check the routing and external IP being used eg. for comparison with Cloudflare / Firewall rules

• main.py - the code
• requirements.txt - the pip modules to bootstrap
• deploy.sh - upload the code and deps

Response is HTTP status code and message, then the raw JSON results

200 OK

}

For IPv6 the format will be more like:

  "ip": "1234:5678:9012:34::a",
  "ip_decimal": 12345678901234567890123456789012345678,

Upload the function to GCF in the current GCP project - this script will call gcloud functions deploy with the required switches:

./deploy.sh
