README

This repository provides Bref layers to run Symfony Runtime applications on AWS Lambda. It is automatically updated to sync with the changes in Bref. These layers are just replacing Bref's "function layer" with a new boostrap file. See the Dockerfile.

You will find more information how to run your applicaiton with the runtime component at https://github.com/php-runtime/bref

Install and configure

composer require runtime/bref-layer
# serverless.yml
service: appgit init

provider:
    name: aws
    region: us-east-1
    runtime: provided.al2

plugins:
    - ./vendor/runtime/bref-layer # <----- Add the extra Serverless plugin

functions:
    website:
        handler: public/index.php
        layers:
            - ${runtime-bref:php-80}
        events:
            -   httpApi: '*'

You will use the same layer for console applications, PSR-11, PSR-15, Laravel or Symfony applications. Anything the Runtime component supports.

Available layers

These are the available layers:

  • ${runtime-bref:php-81}
  • ${runtime-bref:php-80}
  • ${runtime-bref:php-74}
  • ${runtime-bref:php-73}

FAQ

Can I use custom php extensions?

Yes, you can. See the bref/extra-php-extensions package.

Do I need to install bref/bref?

The bref/bref package includes both layers and a lot of features to make it easier to write applications on AWS Lambda. You do not have to include bref/bref if you only want the layers. But most HTTP applications probably will.

Why not include this package in bref/bref?

There is an open PR to do just that. There is also an open PR to make the function layer support the runtime component natively.

Until any of these PRs are merged, we have this layer to help making a good experience as possible for the runtime users.

Why not use the layer from bref/extra-php-extensions?

The bref/extra-php-extensions has a layer called ${bref-extra:symfony-runtime-php-74}. It adds the custom bootstrap file needed for the Runtime component.

AWS has a hard limit on max 5 layers per function. So instead of using two layers (${bref:layer.php-80} + ${bref-extra:symfony-runtime-php-74}) one can use only ${runtime-bref:php-80}.

What is your relation to Bref?

We LOVE Bref. They are the best ever. Consider sponsoring Matthieu Napoli for his work.
