Deploying a Laravel Application to Elastic Beanstalk

Laravel is an open source, model-view-controller (MVC) framework for PHP. This tutorial walks you through the process of generating a Laravel application, deploying it to an AWS Elastic Beanstalk environment, and configuring it to connect to an Amazon Relational Database Service (Amazon RDS) database instance.

Prerequisites

This tutorial assumes that you have some knowledge of basic Elastic Beanstalk operations and the Elastic Beanstalk console. If you haven't already, follow the instructions in Getting Started Using Elastic Beanstalk to launch your first Elastic Beanstalk environment.

To follow the procedures in this guide, you will need a command line terminal or shell to run commands. Commands are shown in listings preceded by a prompt symbol ($) and the name of the current directory, when appropriate:

~/eb-project$ this is a command this is output

On Linux and macOS, use your preferred shell and package manager. On Windows 10, you can install the Windows Subsystem for Linux to get a Windows-integrated version of Ubuntu and Bash.

Laravel requires PHP 5.5.9 or later and the mbstring extension for PHP. In this tutorial we use PHP 7.0 and the corresponding Elastic Beanstalk platform configuration. Install PHP and Composer by following the instructions at Setting Up your PHP Development Environment.

Launch an Elastic Beanstalk Environment

Use the AWS Management Console to create an Elastic Beanstalk environment. Choose the PHP platform and accept the default settings and sample code.

To launch an environment (console)

  1. Open the Elastic Beanstalk console using this preconfigured link: console.aws.amazon.com/elasticbeanstalk/home#/newApplication?applicationName=tutorials&environmentType=LoadBalanced&instanceType=t2.micro

  2. For Platform, choose the platform that matches the language used by your application.

  3. For Application code, choose Sample application.

  4. Choose Review and launch.

  5. Review the available options. When you're satisfied with them, choose Create app.

Environment creation takes about 5 minutes and creates the following resources:

  • EC2 instance – An Amazon Elastic Compute Cloud (Amazon EC2) virtual machine configured to run web apps on the platform that you choose.

    Each platform runs a specific set of software, configuration files, and scripts to support a specific language version, framework, web container, or combination thereof. Most platforms use either Apache or nginx as a reverse proxy that sits in front of your web app, forwards requests to it, serves static assets, and generates access and error logs.

  • Instance security group – An Amazon EC2 security group configured to allow ingress on port 80. This resource lets HTTP traffic from the load balancer reach the EC2 instance running your web app. By default, traffic isn't allowed on other ports.

  • Load balancer – An Elastic Load Balancing load balancer configured to distribute requests to the instances running your application. A load balancer also eliminates the need to expose your instances directly to the internet.

  • Load balancer security group – An Amazon EC2 security group configured to allow ingress on port 80. This resource lets HTTP traffic from the internet reach the load balancer. By default, traffic isn't allowed on other ports.

  • Auto Scaling group – An Auto Scaling group configured to replace an instance if it is terminated or becomes unavailable.

  • Amazon S3 bucket – A storage location for your source code, logs, and other artifacts that are created when you use Elastic Beanstalk.

  • Amazon CloudWatch alarms – Two CloudWatch alarms that monitor the load on the instances in your environment and are triggered if the load is too high or too low. When an alarm is triggered, your Auto Scaling group scales up or down in response.

  • AWS CloudFormation stack – Elastic Beanstalk uses AWS CloudFormation to launch the resources in your environment and propagate configuration changes. The resources are defined in a template that you can view in the AWS CloudFormation console.

  • Domain name – A domain name that routes to your web app in the form subdomain.region.elasticbeanstalk.com.

All of these resources are managed by Elastic Beanstalk. When you terminate your environment, Elastic Beanstalk terminates all the resources that it contains.

Note

The Amazon S3 bucket that Elastic Beanstalk creates is shared between environments and is not deleted during environment termination. For more information, see Using Elastic Beanstalk with Amazon S3.

Install Laravel and Generate a Website

Composer can install Laravel and create a working project with one command:

~$ composer create-project --prefer-dist laravel/laravel eb-laravel Installing laravel/laravel (v5.5.28) - Installing laravel/laravel (v5.5.28): Downloading (100%) Created project in eb-laravel > @php -r "file_exists('.env') || copy('.env.example', '.env');" Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 70 installs, 0 updates, 0 removals - Installing symfony/thanks (v1.0.7): Downloading (100%) - Installing hamcrest/hamcrest-php (v2.0.0): Downloading (100%) - Installing mockery/mockery (1.0): Downloading (100%) - Installing vlucas/phpdotenv (v2.4.0): Downloading (100%) - Installing symfony/css-selector (v3.4.8): Downloading (100%) - Installing tijsverkoyen/css-to-inline-styles (2.2.1): Downloading (100%) ...

Composer installs Laravel and its dependencies, and generates a default project.

If you run into any issues installing Laravel, go to the installation topic in the official documentation: https://laravel.com/docs/5.2

Deploy Your Application

Create a source bundle containing the files created by Composer. The following command creates a source bundle named laravel-default.zip. It excludes files in the vendor folder, which take up a lot of space and are not necessary for deploying your application to Elastic Beanstalk.

eb-laravel zip ../laravel-default.zip -r * .[^.]* -x "vendor/*"

Upload the source bundle to Elastic Beanstalk to deploy Laravel to your environment.

To deploy a source bundle

  1. Open the Elastic Beanstalk console.

  2. Navigate to the management page for your environment.

  3. Choose Upload and Deploy.

  4. Choose Choose File and use the dialog box to select the source bundle.

  5. Choose Deploy.

  6. When the deployment completes, choose the site URL to open your website in a new tab.

Note

To optimize the source bundle further, initialize a Git repository and use the git archive command to create the source bundle. The default Laravel project includes a .gitignore file that tells Git to exclude the vendor folder and other files that are not required for deployment.

Configure Composer Settings

When the deployment completes, click the URL to open your Laravel application in the browser:

What's this? By default, Elastic Beanstalk serves the root of your project at the root path of the web site. In this case, though, the default page (index.php) is one level down in the public folder. You can verify this by adding /public to the URL. For example, http://laravel.us-west-2.elasticbeanstalk.com/public.

To serve the Laravel application at the root path, use the Elastic Beanstalk console to configure the document root for the web site.

To configure your web site's document root

  1. Open the Elastic Beanstalk console.

  2. Navigate to the management page for your environment.

  3. Choose Configuration.

  4. On the Software configuration card, choose Modify.

  5. For Document Root, type /public.

  6. Choose Apply.

  7. When the update is complete, click the URL to reopen your site in the browser.

So far, so good. Next you'll add a database to your environment and configure Laravel to connect to it.

Add a Database to Your Environment

Launch an RDS DB instance in your Elastic Beanstalk environment. You can use MySQL, SQLServer, or PostgreSQL databases with Laravel on Elastic Beanstalk. For this example, we'll use MySQL.

To add an RDS DB instance to your Elastic Beanstalk environment

  1. Open the Elastic Beanstalk console.

  2. Navigate to the management page for your environment.

  3. Choose Configuration.

  4. On the Database configuration card, choose Modify.

  5. For Engine, choose mysql.

  6. Type a master username and password. Elastic Beanstalk will provide these values to your application using environment properties.

  7. Choose Apply.

Creating a database instance takes about 10 minutes. In the meantime, you can update your source code to read connection information from the environment. Elastic Beanstalk provides connection details using environment variables, such as RDS_HOSTNAME, that you can access from your application.

Laravel's database configuration is stored in a file named database.php in the config folder in your project code. Find the mysql and modify the the host, database, username, and password variables to read the corresponding values from Elastic Beanstalk:

Example ~/eb-laravel/config/database.php

... 'connections' => [ 'sqlite' => [ 'driver' => 'sqlite', 'database' => env('DB_DATABASE', database_path('database.sqlite')), 'prefix' => '', ], 'mysql' => [ 'driver' => 'mysql', 'host' => env('RDS_HOSTNAME', '127.0.0.1'), 'port' => env('RDS_PORT', '3306'), 'database' => env('RDS_DB_NAME', 'forge'), 'username' => env('RDS_USERNAME', 'forge'), 'password' => env('RDS_PASSWORD', ''), 'unix_socket' => env('DB_SOCKET', ''), 'charset' => 'utf8mb4', 'collation' => 'utf8mb4_unicode_ci', 'prefix' => '', 'strict' => true, 'engine' => null, ], ...

To verify that the database connection is configured correctly, add code to index.php to connect to the database and add some code to the default response:

Example ~/eb-laravel/public/index.php

... if(DB::connection()->getDatabaseName()) { echo "Connected to database ".DB::connection()->getDatabaseName(); } $response->send(); ...

When the DB instance has finished launching, bundle and deploy the updated application to your environment.

To update your Elastic Beanstalk environment

  1. Create a new source bundle:

    ~/eb-laravel$ zip ../laravel-v2-rds.zip -r * .[^.]* -x "vendor/*"
  2. Open the Elastic Beanstalk console.

  3. Navigate to the management page for your environment.

  4. Choose Upload and Deploy.

  5. Choose Browse, and upload laravel-v2-rds.zip.

  6. Choose Deploy.

Deploying a new version of your application takes less than a minute. When the deployment is complete, refresh the web page again to verify that the database connection succeeded:

Cleanup

When you finish working with Elastic Beanstalk, you can terminate your environment. Elastic Beanstalk terminates all AWS resources associated with your environment, such as Amazon EC2 instances, database instances, load balancers, security groups, and alarms.

To terminate your Elastic Beanstalk environment

  1. Open the Elastic Beanstalk console.

  2. Navigate to the management page for your environment.

  3. Choose Actions, and then choose Terminate Environment.

  4. In the Confirm Termination dialog box, type the environment name, and then choose Terminate.

With Elastic Beanstalk, you can easily create a new environment for your application at any time.

In addition, you can terminate database resources that you created outside of your Elastic Beanstalk environment. When you terminate an Amazon RDS database instance, you can take a snapshot and restore the data to another instance later.

To terminate your RDS DB instance

  1. Open the Amazon RDS console.

  2. Choose Instances.

  3. Choose your DB instance.

  4. Choose Instance actions, and then choose Delete.

  5. Choose whether to create a snapshot, and then choose Delete.

Next Steps

For more information about Laravel, go to the tutorial at laravel.com.

As you continue to develop your application, you'll probably want a way to manage environments and deploy your application without manually creating a .zip file and uploading it to the Elastic Beanstalk console. The Elastic Beanstalk Command Line Interface (EB CLI) provides easy-to-use commands for creating, configuring, and deploying applications to Elastic Beanstalk environments from the command line.

In this tutorial, you used the Elastic Beanstalk console to configure composer options. To make this configuration part of your application source, you can use a configuration file like the following.

Example .ebextensions/composer.config

option_settings: aws:elasticbeanstalk:container:php:phpini: document_root: /public

For more information, see Advanced Environment Customization with Configuration Files (.ebextensions).

Running an Amazon RDS DB instance in your Elastic Beanstalk environment is great for development and testing, but it ties the lifecycle of your database to your environment. See Adding an Amazon RDS DB Instance to Your PHP Application Environment for instructions on connecting to a database running outside of your environment.

Finally, if you plan on using your application in a production environment, you will want to configure a custom domain name for your environment and enable HTTPS for secure connections.
