# Amazon Neptune version 4 signing example (version v2)

# The following script requires python 3.6+
#    (sudo yum install python36 python36-virtualenv python36-pip)
# => the reason is that we're using urllib.parse() to manually encode URL
#    parameters: the problem here is that SIGV4 encoding requires whitespaces
#    to be encoded as %20 rather than not or using '+', as done by previous/
#    default versions of the library.

// This script uploads your assets to the CDK staging bucket in S3 (just as cdk deploy would)
// and writes out two files:
//  - parameters.ini to use in CLI deployments (see instructions below)
//  - parameters.json to use in AWS CodePipeline for CloudFormation deployments
//
// Installation instructions:
// - Save this script cdk-package.ts to the root of your CDK repo (i.e. next to cdk.json) and make it executable
// - Install script dependencies: npm install jsonpath aws-sdk adm-zip @types/jsonpath @types/adm-zip

Set up VGW on AWS with OpenSwan

You will need 2 VPCs. The Internet VPC will have the Internet Gateway and the OpenSwan EC2 instance. The Project VPC will have your application or Kubernetes cluster.

Internet VPC

• VPC CIDR: 10.230.30.0/24
• Private Subnet: 10.230.30.128/25 - Route Table with 0.0.0.0/0 to NAT
• Public Subnet: 10.230.30.0/25 - Route Table with 0.0.0.0/0 to IGW, 10.224.36.0/23 to OpenSwan Instance
• NAT Gateway in the public subnet with an IP of 52.15.61.171
