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.

About this skill

Trigger

Setup and initialization guide for developing AWS CDK (Cloud Development Kit) applications in Python. This skill enables users to configure environment prerequisites, create new CDK projects, manage dependencies, and deploy to AWS.

Colophon for this issue

Colophon

How this issue was made

Source

github.com/github/awesome-copilot, branch main, last pushed 24 September 2026.

Licence

MIT — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

200 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. 2 distinct layouts observed: .github/skills/*/SKILL.md, skills/*/SKILL.md.

Authorship

3 of 200 skills are installed into the repository rather than published from it. They are shelved in the closing “Credited skills” part and remain the work of their own authors. A skill counts as credited when its only copy lives under one agent’s dot directory; visible directories, per-agent mirror sets, and skills installable from this repository on skills.sh all count as published.

Issue colours

Resolved from a curated brand profile — hue 295°, chroma 0.190. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Shifted “14 headings” from h1 to h2 so the skill title is the only h1.

Spec compliance

Every skill satisfies the Agent Skills specification’s frontmatter rules.

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .github/plugin/marketplace.json by GitHub, declaring 162 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /github/awesome-copilot.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
