Question:

Php Error Solved- Instance deployment failed to install Composer dependencies

When encountering an issue during the deployment of a PHP application with Composer dependencies, there could be several reasons behind the issue.

Check PHP Version:

Ensure that the PHP version specified in your composer.json file is compatible with your hosting environment. Some packages may have minimum PHP version requirements, and if your hosting environment uses an older version, it could lead to dependency installation issues. Update your PHP version if necessary.

Check Composer Version and memory limit:

After confirming the above mention dependencies are working fine, it's now not necessary to upload the whole vendor folder on your Git repository when deploying a Laravel utility on Elastic Beanstalk. Committing the vendor folder is usually now not recommended because it may bloat your repository and purpose model conflicts.

Instead Update Composer on Your Local Machine using

composer self-replace

Then update the composer.json then run

composer install

This will update your vendor directory with the latest dependencies based on the changes you made to composer.json.

then commit composer.json and composer.lock:

git add composer.json composer.lock

git commit -m "Update composer.json and composer.lock"

git push

Your Elastic Beanstalk environment should be configured to run Composer during deployment. You've already created the .ebextensions folder, but you need to ensure that your environment is set up correctly to run Composer during the deployment process.

Create a file named .ebextensions/01-composer-install.config with the following content:

container_commands:

01_update_composer:

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

02_install_dependencies:

command: "/usr/bin/composer.phar install --no-dev --optimize-autoloader"

Elastic Beanstalk will use the updated composer.json and composer.lock files to install the necessary dependencies during deployment.
