After working with Imager in a fortrabbit-hosted Craft 3 project, I published a storage driver that André claimed would be easy to write. (It was.) The Imager Storage Driver for fortrabbit Object Storage makes it possible to store Imager’s transforms in fortrabbit’s Object Storage Volumes, which you’ll want to do if you’re working with fortrabbit’s Pro Stack. (Imager’s
aws driver doesn’t work because fortrabbit’s endpoints are different.)
If you have an app running on the Pro Stack—not the Univeral Stack, which uses something different called Web Storage—you can use Imager for your transforms and have access to all kinds of magic. Here’s how to get those transforms stored on fortrabbit’s Object Storage.
What you need:
- a site built with Craft CMS 3+
- Imager 2+
- fortrabbit Pro Stack with Object Storage
1. Install the Imager plugin if you haven’t already.
Require the Imager from your project directory, then install from Settings → Plugins in the Craft control panel or via
./craft install/plugin imager.
2. Install the Imager fortrabbit Object Storage driver.
Again install via Settings → Plugins in the Control panel or
./craft install plugin imager-fortrabbit-object-storage-driver.
3. Configure the driver for your site.
If you don’t already have Imager creating transforms in your templates, pick an Asset somewhere and set up a test:
You should get a nicely-resized image, because Imager will store its transforms in
web/imager by default. Next we’ll have it store those transforms with fortrabbit Object Storage instead of local storage.
config/imager.php if you don’t already have it. There are loads of available settings, so while you should season to taste we’ll focus only on transforms here. If you configured your site using environment variables like fortrabbit suggests and want transforms stored in a folder called “transforms,” this should almost work right out of the gate:
You’ll need to add an
IMAGER_URL environment variable set to your public, absolute Object Storage URL. That’ll look something like
https://my-app.objects.frb.io/. The entire .env would look something like this, where
my-app is a placeholder for your actual app handle:
You could also just hardcode that URL into
config/imager.php if you wanted to, but what fun is that?
4. Make sure it works!
Clear out Imager’s transform caches and refresh your test page. You should see your new transforms being stored to and served from fortrabbit’s Object Storage.
Leave a comment or open an issue on GitHub if you run into any trouble, and otherwise enjoy those fortrabbit-stored transforms!
