AWS-CLI Elasticbeanstalk

Installation

# Install/upgrade
$ pip install awscli --upgrade --user

# Verify installation
$ aws --version

The --upgrade option tells pip to upgrade any requirements that are already installed. The --user option tells pip to install the program to a subdirectory of your user directory to avoid modifying libraries used by your operating system.

Commands

For the full list of available commands, you can refer the official documentation here.

Setup Application

To create an application, we need to configure certain parameters. There are two options to create the application:

Specifying all the parameters in the json file
Specifying it in the cli when running aws-cli

Let's take a look at the first option. To print out the sample template of parameters that needs to be configured:

$ aws elasticbeanstalk create-application --generate-cli-skeleton

Output:

{
    "ApplicationName": "",
    "Description": "",
    "ResourceLifecycleConfig": {
        "ServiceRole": "",
        "VersionLifecycleConfig": {
            "MaxCountRule": {
                "Enabled": true,
                "MaxCount": 0,
                "DeleteSourceFromS3": true
            },
            "MaxAgeRule": {
                "Enabled": true,
                "MaxAgeInDays": 0,
                "DeleteSourceFromS3": true
            }
        }
    }
}

Save the output as config.json, fill in the name and desciption, and run the following command:

$ aws elasticbeanstalk create-application --cli-input-json config.json

For the second option, you can just run the following:

$ aws elasticbeanstalk create-application --application-name "test-application" \
--description "This is a test application"

Output:

Update application

The only fields that can be updated is the application description:

$ aws elasticbeanstalk update-application --application-name test-application --description "this is an edited description"

Delete application

Note: You cannot delete an application that has a running environment.

To delete the previous application that we created:

$ aws elasticbeanstalk delete-application --application-name test-application

In order to force delete an application that contains running environments:

$ aws elasticbeanstalk delete-application --application-name test-application --terminate-env-by-force true

Setup environment

If you have a running environment and wish to see the configuration:

$ aws elasticbeanstalk describe-configuration-settings  --application test-application --environment-name test-application-development
