README

A lightweight PHP image resizer

Out of the box usage

1. Run composer install
2. Set up environment variables
3. Resize your images

Setup

The image resizer is intended to live as a standalone microservice behind a CDN. The first request for a query combination http://resizer-url.com/resize/?source=http://image-source.com/images/image.jpg&height=300&width=400 will fall through to the resizer instance but any subsequent requests should be cached by the CDN.

Environment Variables

The resizer depends on a few configurable environment variables (can be loaded from a dotenv file):

• ALLOWED_HOSTS - a comma separated string of whitelisted domains
• CACHE_EXPIRATION_HOURS - length (in hours) to set Cache-Control with the max-age directive and Expires headers. Any CDN should obey your cache rules and cache objects appropriately.
• APP_ENV - app environment

Best Practices

In light of exploits like https://imagetragick.com/, we recommend that your implementation:

1. Uses the latest version of ImageMagick
2. Follows mitigation procedures listed on https://imagetragick.com/
3. Has severely restricted access to any other resources (on the same network or otherwise)
4. Only processes images from sources you whitelist

Healthcheck

healthcheck.php will return a 200 for Load Balancer health pings.

Tests

Run phpunit
