Building my personal AWS infrastructure with AWS CDK

The goal of this repository is to create the AWS CDK code for my personal cloud infrastructure for study purposes.

Installing AWS CDK

npm install -g aws-cdk
cdk --version

Creating a new CDK project with cdk init

mkdir iac
cd iac
cdk init app --language=python

Activate the virtual environment and install requirements:

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

Creating a new CDK project with Poetry

First, install Poetry.

curl -sSL https://install.python-poetry.org | python3 -
poetry --version

Next, create a new boilerplate files and folder using Poetry.

poetry new iac --name src
cd iac

Then, add the following configurations about virtual environments.

poetry config --local virtualenvs.in-project true
poetry config --local virtualenvs.create true

And add CDK to the project.

poetry add aws-cdk-lib
poetry install

And finally you need to create the necessary files expected by CDK.
Below are just examples describing the expected structure of each file. cdk.json

{ "app":"poetry run python app.py"}

app.py

import aws_cdk as cdk

from src.cdk_stack import MyStack

app=cdk.App()
MyStack(app,"MyStack")
app.synth()

src/cdk_stack.py

import aws_cdk as cdk

from aws_cdk import aws_s3 as s3
from constructs import Construct

class MyStack(cdk.Stack):
    """CreatesaStackwith a bucket."""
    def __init__(
        self, 
        scope: Construct,
        id:str,
        **kwargs,
        )-> None:
        super().__init__(scope, id, **kwargs)
        
        s3.Bucket(
            scope=self,
            id="MyBucket",
            bucket_name="my-bucket-56e143c0",
            removal_policy=cdk.RemovalPolicy.DESTROY,
            auto_delete_objects=True
            )
