How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

  1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
  2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
  3. VPC with NAT, The best of both worlds, AWS services and web.

Jenkinsfile idiosynchrasies with escaping and quotes
node {

echo 'No quotes, pipeline command in single quotes'
sh 'echo $BUILD_NUMBER' // 1
echo 'Double quotes are silently dropped'
sh 'echo "$BUILD_NUMBER"' // 1
echo 'Even escaped with a single backslash they are dropped'
sh 'echo \"$BUILD_NUMBER\"' // 1
echo 'Using two backslashes, the quotes are preserved'
