Deploying Laravel to Elastic Beanstalk: Solve the Permission Denied Error Easily

Deploying a Laravel application to AWS Elastic Beanstalk can sometimes lead to frustrating issues, one of which is the dreaded failed to open stream: Permission denied error. If you have experienced this problem when trying to log information during your deployment, you're not alone. In this guide, we will explore the cause of the issue and detail the steps you can take to resolve it effectively.

Understanding the Problem

When you deploy a Laravel application, the framework generates log files to track errors and application behavior. However, in certain setups on AWS Elastic Beanstalk, you might encounter an error like this:

This error usually indicates that Laravel does not have the correct permissions to write to the log file, which results in failed deployments and a few anxious moments as a developer.

The Root Cause

The problem stems from how log files are being created and the permissions that are applied to them. In many cases, the daily log files are being generated with root permissions, leaving them inaccessible to the webapp user.

A Closer Look at the Deployment Configuration

You may have already tried modifying your .ebextensions configuration files, particularly in eb deploy.config:

While this script seems like it should resolve the permission issues, it may not adequately address the creation of daily log files in a way the Laravel application can utilize.

A Solution to the Permission Denied Error

The effective resolution to this issue is to allow each process to create its own log file. This can be done by modifying the logging configuration in your Laravel application. Here’s how:

Step 1: Update the Logging Configuration

Navigate to your config/logging.php file and make adjustments to the daily log creation process. Below is a recommended configuration change:

Here’s a breakdown of the changes:

Driver: Maintain the daily driver to continue daily logging.

Path: Use php_sapi_name() to customize the log file name based on the PHP server API. This allows each process to have its own log file, eliminating permission issues.

Step 2: Test Your Changes

After updating the logging configuration, deploy your Laravel application to AWS Elastic Beanstalk again. Check the logs directory to ensure that the logs are being created correctly without any permission problems.

Conclusion

By following the steps outlined in this guide, you should be able to resolve the failed to open stream: Permission denied issue in your Laravel application deployment on AWS Elastic Beanstalk. Always ensure to monitor your logs and adjust configurations as required to maintain smooth operations. Happy coding!
