I'm trying to run Laravel in AWS Multicontainer Docker Environments.

I have followed the tutorial on http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker_ecstutorial.html to deploy a simple PHP application with nginx, and it worked. So I have removed all the files in the default php-app folder and installed Laravel and ran composer install locally, and deployed using eb deploy command. However, I received the following error message:

Warning: require(/var/www/html/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /var/www/html/bootstrap/autoload.php on line 17

Fatal error: require(): Failed opening required '/var/www/html/bootstrap/../vendor/autoload.php' (include_path='.:/usr/local/lib/php') in /var/www/html/bootstrap/autoload.php on line 17
