Code for the environment build in the Zero Trust service2service workshop.

Zero Trust Workshop - Service2Service Episode - Code

This repository contains the source code, AWS environment build, of the Zero Trust Service2Service Workshop workshop. It does not contain the source code of the workshop's website.

There are two main CDK stacks in this code:

• ServiceA
• ServiceB

High Level Architecture:

How To Use

Requirements

• python3
• node
• aws-cdk

Steps

1. Clone this repo & cd aws-zerotrust-service2service-workshop

2. Create and activate virtual environment:

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

3. Once the virtual environment is activated, install the required dependencies:

   pip install -r requirements.txt

4. You should now be able to run CDK commands. Start by listing available stacks:

   cdk ls

5. For example, if you want to synthesize the CloudFormation template for a stack:

   cdk synth <StackName>

Specific to this app

# While in the root directory of this repo:
pip3 install aws_requests_auth -t src/lambda/layer/python

Why? I create a Lambda layer that contains the aws_requests_auth package used by Lambda functions. I avoid pushing the package's files to the repo (.gitignore). So you need to pip install the package after cloning this repo. Then at cdk deploy time CDK uses packages installed in ./src/lambda/layer/python to create the Lambda Layer.

Useful commands

• cdk ls list all stacks in the app
• cdk synth emits the synthesized CloudFormation template
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk docs open CDK documentation

Repo structure

This project is initialized by cdk init and has the standard structure of a Python project.
