AWS CDK Construct - export VPC from one stack, import to another

This is an integration test for the NPM module cdk-vpc-export-import.

It also demonstrates how to use multiple stacks to modularize your AWS deployments so that faults in the CDK are isolated to one stack

Integration Test

This needs to be automated. Why the CDK CLI doesn't have a wrapper NPM package by now, I have no idea. I guess that should be next on the list of things I should write.

1. Run the build command. This will cause a synthesis of the stack and unit tests for the stack to run

    yarn run build
   

2. Build the lambda code. AFAICT no toolchain handles this correctly

    cd lambdaSrc
    npm install
    cd ..
   

3. Run the deploy commands for the two stacks. Assumes you have the environment variables or ~/.aws/credentials file mounted

    yarn run deploy dbStack
    yarn run deploy vpcStack 
    yarn run deploy apiStack
   

4. Get the URL for the api gateway in the stack output via copy and paste into the next commands

5. Run the integration test that tests the network connectivity by doing a POST and a GET. Make not of the ID for the GET

    curl -X POST -H "Content-Type: application/json" -d '{"username":"xyz","email":"xyz@example.com"}' <apigatewayurl>/db/id
    curl -s <apigatewayurl>/prod/db/<id returned from the POST>
   

6. destroy the two stacks. Note the reverse order due to dependencies

    yarn run cdk destroy apiStack
    yarn run cdk destroy vpcStack
    yarn run cdk destroy apiStack
