refresh-my-ip

Quick Overview

If you have EC2 instances locked down by IP address, it can be time annoying/frustrating/time-consuming if your IP address changes, or if you work in different locations.

Using the Description field, refresh-my-ip will scan through all of your security groups looking for MyIp and replace the IP address with your current public IP address.

Quick Start

1. Install the app:

   pip install refresh-my-ip

2. In any of your security group ingress rules where you want to automatically refresh the IP address, simply change the description to MyIp.

3. Run refresh-my-ip anytime you want to update all the IP addresses.

Optional Feature

If you don't want to use MyIp in the description, you can pass --match-description along with the text you want to match.

IAM Policy

These are the minimum permissions to run refresh-my-ip.
