OCI NSG Python Script

Table of Contents

About

Oracle Cloud Infrastructure (OCI) NSG Python Script is a script that will create a NSG & associated Security Rules in OCI.

It was created to allow for easy creation of NSGs for use with Cloudflare's IP Lists in mind, but could be adapted to do more than just for Cloudflare's IP Lists. Of couse you could also use Terraform to perform this automations as well which could be included in the future.

The script can currently create a NSG with the following rules:

  • Allow all traffic from Cloudflare IPv4s and/or IPv6s to the TCP HTTP (80) port
  • Allow all traffic from Cloudflare IPv4s and/or IPv6s to the TCP HTTPS (443) port
  • Allow all traffic from Cloudflare IPv4s and/or IPv6s to the UDP HTTPS (443) port for QUIC/HTTP3
