☸️ AWS CDK - Cloud Development Kit

AWS CDK uses the familiarity and expressive power of programming languages for modeling your applications. It provides high-level components called constructs that preconfigure cloud resources with proven defaults, so you can build cloud applications with ease.

Prerequisites​

  • You have python3 installed and setup locally in your system path, refer to the docs for installation
  • You have installed and configured the AWS CDK locally
  • Ensure you have all the required AWS permission and configuration locally

Setup​

  • First, clone the Kubernetes Goat repository locally by running the following command
git clone https://github.com/madhuakula/kubernetes-goat.git
  • Navigate to the folder for setup and installation of the Kubernetes Goat using KiND
cd kubernetes-goat/platforms/aws-kind-ec2-cdk
  • Create a virtualenv (Assume you already have installed Python3 and it's available in the path)
python3 -m venv .venv
  • Activate your virtualenv in MacOS & Linux
source .venv/bin/activate
  • If you are a Windows platform, you would activate the virtualenv by running following command
% .venv\Scripts\activate.bat
  • Once the virtualenv is activated, you can install the required dependencies
pip install -r requirements.txt
  • If your AWS is not bootstrap with CDK, run the following
cdk bootstrap
  • At this point you can now synthesize the CloudFormation template for this code
cdk synth
  • Edit .env file according to your AWS environment
account_number=<1234567890> # Provide your AWS account number
default_region=<us-region-n> # Provide the AWS Region
vpc-id=<vpc-01234abcd> # VPC ID
instance_type=<t2.large or t2.medium> # Instance type t2.micro not recommended
key_pair_name=<kube-goat> # SSH Keypair name without .pem
whitelist_ip=<XX.XX.XX.XX/32> # 0.0.0.0/0 for public access, Recommended to whitelist for your network
  • Now deploy this stack to your default AWS account/region
cdk deploy
  • SSH to the deployed server using the SSH keypair
ssh -i key_pair_name.pem ubuntu@target_server
  • Then to access the Kubernetes Goat locally by running the following command
sudo cd /kubernetes-goat
sudo bash access-kubernetes-goat.sh
danger

To destroy the setup, run the following command in your host system (where CDK was setup initally)

cdk destroy
