AWS Elastic Beanstalk and Composer

Question

I have an application with Composer dependencies which I want to deploy to an Elastic Beanstalk container. However my composer.json file is not in the project root folder.

Answer 1

The syntax has changed slightly as of 2019. To run composer automatically when you deploy via elastic beanstalk, add the following file (01composer.config) to a folder called ".ebextensions" in the root of your repository / code project :

The contents of that file should be a follows, for a simple but effective run of composer each time your code is deployed :

commands:
   composer_update:
      command: export COMPOSER_HOME=/root && /usr/bin/composer.phar self-update

option_settings:
   - namespace: aws:elasticbeanstalk:application:environment
     option_name: COMPOSER_HOME
     value: /root

container_commands:
  01-install_dependencies:
       command: "php /usr/bin/composer.phar install"
       cwd: "/var/app/ondeck"
  
  02-optimize:
      command: "php /usr/bin/composer.phar dump-autoload --optimize"
      cwd: "/var/app/ondeck"

Spacing is important. Indent as the code above (copied from a working example, June 2020). The number 01 at the beginning of the file name indicates the running order of these command files. You can change these numbers / order based on your setup. I always put composer 1st in the list.

EDIT: FYI composer install doesn't install composer! It installs the packages within composer. Composer must already be installed, which it should be by default as part of AWS's PHP AMI.
