AWS serverless infrastructure for PHP Laravel applications

Description

Programmatically create the AWS serverless infrastructure for a PHP Laravel application using Terraform.

Thanks to Bref for providing the AWS Lambda layers for PHP.

Deploy a demo application

Create the Terraform project folder

1. Use examples/simple-app as root folder for your new application and include the terraform-aws-serverless-bref inside the modules folder. E.g.:

   cp -r ~/code/terraform-aws-serverless-bref/examples/simple-app ~/code
   cd ~/code/simple-app
   mkdir modules
   cd modules
   cp -r ~/code/terraform-aws-serverless-bref .
   

2. Change directory to the artifact folder:

   cd ~/code/simple-app/artifact
   

Clone the Git repository

1. Create a new or copy an existing Laravel application inside the artifact folder:

   composer create-project laravel/laravel example-app
   cd example-app
   

Build the application

1. Install the Javascript dependecies:

   npm install
   npm build
   

2. Generate the app key:

   php artisan key:generate
   

3. Include the Bref packages:

   composer require bref/bref bref/laravel-bridge --update-with-dependencies
   

4. Install the PHP dependecies:

   composer install
   

5. Create a static configuration cache file:

   php artisan config:cache
   

Build the artifact

1. Delete the existing archive (if it exists):

   rm ../simple-app.zip
   

2. Compress the application in an archive:

   zip -r ../simple-app.zip . -x 'node_modules/*' 'public/storage/*' 'resources/assets/*' 'storage/*' 'tests/*'
   

   If you want to exclude additional directories or files, add their patch after the -x argument.

3. Create a checksum for the archive:

   cd ~/code/simple-app/artifact
   openssl dgst -sha256 -binary simple-app.zip | openssl enc -base64 > simple-app.zip.sha256
   

Configure the Terraform module

1. Create the terraform.tfvars file:

   cd ~/code/simple-app/
   cp terraform.tfvars.example terraform.tfvars
   

2. Edit the terraform.tfvars file:

   vi terraform.tfvars
   

   Please, make sure to use the AWS Lambda layers matching version of the bref/bref PHP package for the exact region you are provisioning the infrastructure to.

Provision the infrastrure and deploy the application

1. Initate Terraform:

   terraform init
   

2. Preview the infrastructure:

   terraform plan
   

3. Create the infrastructure:

   terraform apply
   # Review and respond with "yes"
