README

This middlware will ensure that your Laravel app will correctly recognise secure requests when running on Elastic Beanstalk with a Load Balancer. NOTE: make sure your web server is not publicly accessible and that the Load Balancer only have access (you can manage that through AWS security groups).

There is also a gist that does the exact same thing.

Installation

You can install this middleware through Composer

composer require peppeocchi/laravel-elb-middleware

Usage

The simplest way to use the middleware is to add it as a global middleware in app/Http/Kernel.php

...
class Kernel extends HttpKernel
{
    /**
     * The application's global HTTP middleware stack.
     *
     * These middleware are run during every request to your application.
     *
     * @var array
     */
    protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \GO\ElasticBeanstalkHttps::class
    ];
...

but you are free to add it to a middleware group or directly into your controllers.

TL;DR

On Elastic Beanstalk (with a load balancer), all the requests are being "proxied" to port 80. The load balancer will add the x-forwarded-* headers to the request.

Laravel Request inherits from Symfony\Component\HttpFoundation\Request, so it already supports the x-forwarded-* headers, but it needs to be configured to look at those headers or you are going to get incorrect informations about the request (eg. $request->isSecure() will always return false).

The Amazon ELB don't have a static IP or a range to target, so you'll need to trust all proxies. Of course you need to make sure your web server will respond only to the load balancer.
