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.

Note this only adds the host to settings - the health check system still requires / to return 200 OK, unless configured differently in EB.

Installation

Simply add ebhealthcheck.apps.EBHealthCheckConfig to your INSTALLED_APPS:

INSTALLED_APPS = [
    ...
    'ebhealthcheck.apps.EBHealthCheckConfig',
    ...
]
