Django app to add an instance's public IP to ALLOWED_HOSTS for Elastic Beanstalk's health check system

django-ebhealthcheck

By default, Elastic Beanstalk's health check system uses the public IP of each load balanced instance as the request's host header when making a request. Unless added to ALLOWED_HOSTS, this causes Django to return a 400 Bad Request and a failed health check.

This app dynamically adds your instance's public IP address to Django's ALLOWED_HOSTS setting to permit health checks to succeed. This happens upon application start.

Version 2.0.0 and higher supports IMDSv2. If you are using v1 and cannot upgrade, use version 1 of this library instead (pip install django-ebhealthcheck<2.0.0).
