AWS CDK Python Setup Instructions This skill provides setup guidance for working with AWS CDK (Cloud Development Kit) projects using Python . Prerequisites Before starting, ensure the following tools are installed: Node.js ≥ 14.15.0 — Required for the AWS CDK CLI Python ≥ 3.7 — Used for writing CDK code AWS CLI — Manages credentials and resources Git — Version control and project management Installation Steps 1. Install AWS CDK CLI npm install -g aws-cdk cdk --version 2. Configure AWS Credentials
Install AWS CLI (if not installed)
brew install awscli
Configure credentials
aws configure Enter your AWS Access Key, Secret Access Key, default region, and output format when prompted. 3. Create a New CDK Project mkdir my-cdk-project cd my-cdk-project cdk init app --language python Your project will include: app.py — Main application entry point my_cdk_project/ — CDK stack definitions requirements.txt — Python dependencies cdk.json — Configuration file 4. Set Up Python Virtual Environment
macOS/Linux
source .venv/bin/activate
Windows
.venv \ Scripts \ activate 5. Install Python Dependencies pip install -r requirements.txt Primary dependencies: aws-cdk-lib — Core CDK constructs constructs — Base construct library Development Workflow Synthesize CloudFormation Templates cdk synth Generates cdk.out/ containing CloudFormation templates. Deploy Stacks to AWS cdk deploy Reviews and confirms deployment to the configured AWS account. Bootstrap (First Deployment Only) cdk bootstrap Prepares environment resources like S3 buckets for asset storage. Best Practices Always activate the virtual environment before working. Run cdk diff before deployment to preview changes. Use development accounts for testing. Follow Pythonic naming and directory conventions. Keep requirements.txt pinned for consistent builds. Troubleshooting Tips If issues occur, check: AWS credentials are correctly configured. Default region is set properly. Node.js and Python versions meet minimum requirements. Run cdk doctor to diagnose environment issues.
