With AWS CDK, we can define an infrastructure using familiar languages (Python, JS, Java, etc) . The code will be compiled into a cloud formation JSON and deployed as a cloud formation stack. Later we can diff the changes made before redeploy.

Install

brew install node
npm install -g aws-cdk

Initialize

cdk init app --language python

python3 -m venv .venv
source .venv/bin/activate
python -m pip install -r requirements.txt

pip install aws-cdk.aws-s3 # module to manage s3

Define

Edit {project_name}/{project_name}_stack.py

from aws_cdk import core
from aws_cdk import aws_s3 as s3


class FnInfraStack(core.Stack):

    def __init__(self, scope: core.Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        s3.bucket(self, "TestingBucketVarokas", versioned=True, )
