Media Fallback

This Chassis extension adds an Nginx rule within your Chassis virtual machine to fall back to production URLs for any local media request which fails with a "404 not found" error. This allows you to run a fully functional virtual machine with a much smaller backup of the uploads/ folder than would normally be necessary, because any image which is not available locally within the VM can then be requested from a live site instead.

Usage

  1. Clone this into the extensions folder of your Chassis installation, or list chassis/media_fallback in your Chassis configuration file's extensions list.
  2. Add a media_fallback: key to your configuration file specifying the URI for a deployed environment's content folder (example below).
  3. Run vagrant up if you have not yet initialized your virtual machine, or vagrant provision if your VM is already up and running.

A request to an image path within your VM that 404s should now attempt to retrieve that image from production (or staging, etcetera, depending on configuration).

Example Configuration

The value of the media_fallback key should always be the path to a content folder within a deployed site.

Assuming you are creating a local environment for the website https://example.com, which uses the standard WordPress directory path wp-content, you may enable your VM to fall back to this site with the following configuration:

# config.local.yaml

media_fallback: 'https://example.com/wp-content'
