AWS Elastic Beanstalk
Developer Guide (API Version 2010-12-01)

eb init


Sets default values for Elastic Beanstalk applications created with EB CLI by prompting you with a series of questions.


The values you set with init apply only to the current directory and repository.


eb init

eb init application-name


If you run eb init without specifying any options, the EB CLI prompts you to enter a value for each setting.


To use eb init to create a new key pair, you must have ssh-keygen installed on your local machine and available from the command line.





Forces EB CLI to prompt you to provide a value for every eb init command option.


The init command prompts you to provide values for eb init command options that do not have a (default) value. After the first time you run the eb init command in a directory, EB CLI might not prompt you about any command options. Therefore, use the --interactive option when you want to change a setting that you previously set.

-k keyname

--keyname keyname

The name of the Amazon EC2 key pair to use with the Secure Shell (SSH) client to securely log in to the Amazon EC2 instances running your Elastic Beanstalk application.

--modules folder-1 folder-2

List of child directories to initialize. Only for use with Compose Environments.

-p platform-name

--platform platform-name

Specify the platform to skip interactive configuration. The platform name can include a version if the platform supports multiple configurations. If you do not specify a configuration version, EB CLI uses the most recent configuration. Use eb platform list to see a list of available platforms.

For example: php, PHP, php5.5, "PHP 5.5", node.js, "64bit Amazon Linux 2014.03 v1.0.7 running PHP 5.5"


When you specify this option, then EB CLI does not prompt you for values for any other options. Instead, it assumes default values for each option. You can specify options for anything for which you do not want to use default values.

--source codecommit/repository-name/branch-name

AWS CodeCommit repository and branch. See Using the EB CLI with AWS CodeCommit.

Common options

CodeBuild Support

If you run eb init in a folder that contains a buildspec.yml file, Elastic Beanstalk parses the file for an eb_codebuild_settings entry with the following format:

eb_codebuild_settings: CodeBuildServiceRole: role-name ComputeType: size Image: image Timeout: minutes

The name (not ARN) of the IAM role for AWS CodeBuild. This value is required and if omitted any subsequent eb create or eb deploy command fails.


The amount of resources for the Docker container. Valid values are BUILD_GENERAL1_SMALL, BUILD_GENERAL1_MEDIUM, and BUILD_GENERAL1_LARGE.


The name of the Docker Hub or Amazon ECR image that AWS CodeBuild creates for Elastic Beanstalk. This value is optional and if omitted the eb init command prompts you for a platform and other options. see Build Environment Reference for AWS CodeBuild for a list of images.


The duration, in minutes, that the AWS CodeBuild build runs before timing out. This value is optional. See Create a Build Project in AWS CodeBuild for the default value and range of values.

Learn more about AWS CodeBuild support in Elastic Beanstalk in the Using the EB CLI with AWS CodeBuild topic.


If successful, the command guides you through setting up a new Elastic Beanstalk application through a series of prompts.


The following example request initializes EB CLI and prompts you to enter information about your application. Replace the red placeholder text with your own values.
