Difficulty: EasyAWS Elastic Beanstalk

A developer is deploying a web application using AWS Elastic Beanstalk. The developer wants to include custom configuration files (with a `.config` extension) to install packages and define environment properties. In which directory at the root of the application source bundle must the developer place these files to ensure they are processed during deployment?

  1. A
    ebextensions
  2. B
    .elasticbeanstalk
  3. .ebextensionsAnswer
  4. D
    .platform

Answer

The `.ebextensions` directory at the root of the application source bundle.
To customize the EC2 instances in an Elastic Beanstalk environment, configuration files (ending in `.config`) must be placed in a directory named `.ebextensions` at the root of the application source bundle. Elastic Beanstalk automatically detects and applies these configurations during deployment.

Step-by-Step Solution

1
Identify where Elastic Beanstalk looks for configuration files in the source bundle.
The platform search mechanism looks at the root of the uploaded zip source bundle.
Elastic Beanstalk needs a standard, predictable location to find customization files.
2
Determine the exact directory naming convention.
The required directory name must start with a period and be followed by 'ebextensions' (resulting in `.ebextensions`).
Omitting the leading period or using a different name will cause the deployment agent to ignore the customization files.
