AWS CDK code examples

This AWS CDK code example deploys stacks containing AWS constructs to your AWS account's CloudFormation.

The development and deployment are performed on your AWS account's EC2 instances with necessary permission, please double-check your EC2 instance role policies if any permission issues occur.

Prerequisites

Install npm:

# Download nvm script
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

export NVM_DIR="$HOME/.nvm"                                                                              
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

# Install latest CDK-supported Node.js and npm
# NOTE: latest node version is not always supported by CDK, double-check before installation
nvm install 17.3.0

# Check installation
node -v
npm -v

Install AWS CDK:

npm install -g aws-cdk

# Check installation
cdk --version

Bootstrapping:

# Replace contents in <> with your AWS account number and region
cdk bootstrap aws://<ACCOUNT_NUMBER>/<REGION>
