# 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 ```bash npm install -g aws-cdk cdk --version ``` ### 2. Configure AWS Credentials ```bash # 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 ```bash 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 ```bash # macOS/Linux source .venv/bin/activate # Windows .venv\Scripts\activate ``` ### 5. Install Python Dependencies ```bash pip install -r requirements.txt ``` Primary dependencies: - `aws-cdk-lib` — Core CDK constructs - `constructs` — Base construct library --- ## Development Workflow ### Synthesize CloudFormation Templates ```bash cdk synth ``` Generates `cdk.out/` containing CloudFormation templates. ### Deploy Stacks to AWS ```bash cdk deploy ``` Reviews and confirms deployment to the configured AWS account. ### Bootstrap (First Deployment Only) ```bash 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.
