AWS CDK VPC

CDK stack example to create a new VPC with an Amazon EC2 instance as a bastion host to ssh-access via AWS Systems Manager Session Manager.

Note that VPC subnetting is based on the Practical VPC Design suggestions.

Usage

Inside a CDK enabled environment (like docker-aws-cdk), create the python3 virtual environment and install the required dependencies.

 python3 -m venv .env && source .env/bin/activate

$ pip3 install -r requirements.txt

Export CDK_DEFAULT_ACCOUNT, CDK_DEFAULT_REGION and CDK_DEPLOY_REGION env vars.

export CDK_DEFAULT_ACCOUNT=111111111111
export CDK_DEFAULT_REGION=eu-south-1
export CDK_DEPLOY_REGION=eu-south-1

At this point you can now synthesize the CloudFormation template for this code.

$ cdk synth
Resources:
  VPCB9E5F0B4:
    Type: AWS::EC2::VPC
    Properties:
...
...

To install the bootstrap stack into an environment

$ cdk bootstrap
⏳  Bootstrapping environment 111111111111/eu-south-1...

To deploy the stack and create AWS resources

$ cdk deploy
cdk deploy
aws-cdk-vpc: deploying...
aws-cdk-vpc: creating CloudFormation changeset...
