Overview

Forge’s site management dashboard allows you to easily create as many Laravel queue workers as you like. Queue workers will automatically be monitored by Supervisor, and will be restarted if they crash. All workers will start automatically if the server is restarted.

​
Creating A Queue Worker

You can create a new queue worker within the site’s management dashboard. The “New Worker” form is a wrapper around the Laravel queue feature. You can read more about queues in the full Laravel queue documentation. When creating a new queue worker, you may select a version of PHP that is already installed on the server. The selected version of PHP will be used to execute the queue worker.

​
Laravel Horizon

If your Laravel application is using Laravel Horizon, you should not setup queue workers as described above. Instead, you may enable Horizon on Forge using Forge’s “daemon” feature. First, create a server daemon that executes the php artisan horizon Artisan command from your site’s root directory. Next, add the php artisan horizon:terminate Artisan command to your site’s deployment script, as described in Horizon’s deployment documentation. Finally, if you wish to use Horizon’s metrics graphs, you should configure the scheduled job for horizon:snapshot in your application code. In addition, you should define a Scheduler task within Forge for the php artisan schedule:run Artisan command if you have not already done so.

​
Restarting Queue Workers After Deployment

When deploying your application, it is important that your existing queue workers or Horizon processes reflect the latest changes to your application. This can be achieved by gracefully restarting these services from your deployment script: When using queue workers: 
$FORGE_PHP artisan queue:restart
When using Horizon: 
$FORGE_PHP artisan horizon:terminate
The queue:restart command requires a cache driver that persists data between requests. If your application’s cache driver is set to array, the command will fail silently because the array driver stores data in memory that is lost between requests.

​
Circle Permissions

You may grant a circle member authority to create and manage queue workers by granting the site:manage-queues permission.
