Hello Everyone

Welcome to CloudAffaire and this is Debjeet.

In the last blog post, we have discussed Elastic Beanstalk monitoring.

In this blog post, we will discuss Elastic Beanstalk advanced environment customization with configuration files (.ebextensions).

. ebextensions:

You can add AWS Elastic Beanstalk configuration files (.ebextensions) to your web application’s source code to configure your environment and customize the AWS resources that it contains. Configuration files are YAML- or JSON-formatted documents with a .config file extension that you place in a folder named .ebextensions and deploy in your application source bundle. The option_settings section of a configuration file defines values for configuration options. Configuration options let you configure your Elastic Beanstalk environment, the AWS resources in it, and the software that runs your application.

Next, we are going to create a PHP web application using custom VPC and RDS instance configured using .config file placed in .ebextensions directory.

Prerequisite for this demo:

  • One EC2 AWS Linux 2 instance with proper access.

Step 1: Login to the EC2 instance and create your application root directory.

Step 2: Create .ebextentions directory and copy .config and .yml files.

Step 3: Create your custom VPC and get the resource ID’s.

Or you can directly copy resources ID’s from AWS CloudFormation console.

Next, we are going to edit the .config file under .ebextensions directory with resource ID’s

Step 4: Edit the .config file with vpc, subnets id’s.

Step 5: Create your application environment.
