Elastic Beanstalk

 Elastic Beanstalk

Elastic Beanstalk is a fully managed service that makes it easy to deploy and run applications in multiple languages. Here is an example of how to deploy a Python Flask application to Elastic Beanstalk using the AWS SDK for Python (boto3):

python

import boto3

from zipfile import ZipFile

elasticbeanstalk = boto3.client('elasticbeanstalk')

application_name = 'my-application'

environment_name = 'my-environment'

version_label = 'v1'

# Create a ZIP file of the Flask application

with ZipFile('my-application.zip', 'w') as zip:

    zip.write('application.py')

    zip.write('requirements.txt')

# Upload the ZIP file to S3

s3 = boto3.client('s3')

s3.upload_file('my-application.zip', 'my-bucket', 'my-application.zip')

# Create a new application version

elasticbeanstalk.create_application_version(

    ApplicationName=application_name,

    VersionLabel=version_label,

    SourceBundle={

        'S3Bucket': 'my-bucket',

        'S3Key': 'my-application.zip'

    }

)

# Create a new environment

elasticbeanstalk.create_environment(

    ApplicationName=application_name,

    EnvironmentName=environment_name,

    VersionLabel=version_label,

    SolutionStackName='64bit Amazon Linux 2 v5.4.7 running Python 3.8',

    OptionSettings=[

        {

            'Namespace': 'aws:autoscaling:launchconfiguration',

            'OptionName': 'InstanceType',

            'Value': 't2.micro'

        }

    ]

)

print(f"Flask application deployed to Elastic Beanstalk environment {environment_name}")

This code creates a ZIP file of a Python Flask application, uploads the ZIP file to S3, creates a new application version in Elastic Beanstalk, and creates a new environment for the application. The create_environment method specifies an Amazon Linux 2 environment running Python 3.8 and a t2.micro instance type.
