How are you do access your application container from a custom Lambda handler?

[robmellett]

Hey guys!

I was just playing around with the lambda event handlers.
https://bref.sh/docs/function/handlers.html

I was wondering how you access your application container from the custom handlers though?

When uploading a file to S3, I'd like to trigger a specific artisan command but I'm a little stuck getting the artisan command to run with the s3 event payload.

I feel like I might be missing a step somewhere. Any suggestions would be much appreciated!

functions:
  event:
    handler: serverless-handler.php
    timeout: 10 # in seconds
    events:
      - s3: ${self:custom.bucket}
    layers:
      - ${bref:layer.php-80}

custom:
  bucket: serverless-gifmaker

With a handler like this.

// serverless-handler.php

<?php

namespace App\Lambda;

use App\Console\Kernel;
use Bref\Context\Context;

class S3Handler implements \Bref\Event\Handler
{
    public function handle($event, Context $context)
    {
       // I was trying to do something like this, but I've come to realise
       // I'd need to bootstrap the app, similar to the `artisan` command. 
        app()->make(Kernel::class)->call('generate:gif');

        return 'Hello ' . $event['name'];
    }
}

return new S3Handler();

You can see an example here:  https://github.com/brefphp/laravel-bridge/blob/master/worker.php

@deleugpn this might be something we may want to facilitate in the Laravel bridge, just like parts of brefphp/symfony-bridge#45 ?

Ah, I see now. thanks @mnapoli

I ended up stealing an example from @Nyholm's Laravel php runtime example.

This is what I settled on in the end.

<?php declare(strict_types=1);

use Bref\Context\Context;
use Illuminate\Contracts\Console\Kernel;

require_once __DIR__.'/vendor/autoload.php';

return function ($event, Context $context) {
    static $app;

    if (null === $app) {
        $app = require __DIR__.'/bootstrap/app.php';
    }

    return $app->make(Kernel::class)->call('generate:gif', [
        'payload' => $event
    ]);
};

Thanks for the help guys!

Would you like me to submit a PR to the docs, in case anyone else would need something like this @mnapoli ?

[mnapoli]

A docs PR would be great indeed 👍

This is how I handle this: https://github.com/cgauge/laravel-bref-adapter/blob/master/src/Kernel/SqsHandler.php

Beginning of May I will have some free time again and I would like to try and improve the laravel bridge on this, for sure.
