Stability: Stable

Scheduled Event Producer stack

The code in this directory deploys an AWS Cloud Development Kit (AWS CDK) stack that produces events.

This stack can be deployed in isolation; however, it serves a purpose in this repository's test automation architecture.

Specifically, it deploys a scheduled Amazon EventBridge rule that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic. Many "consumer" Amazon Simple Queue Service (Amazon SQS) topics are subscribed to the SNS topic.

System requirements

  • npm (node.js)
  • python 3.x
  • AWS access key and secret for AWS user with permissions to create the preceding resources
  • Successfully written system parameters

Storing system parameters

Before you get started, execute store_system_parameters.py as described in the code comments:

python3 store_system_parameters.py

AWS CDK setup and deployment

First, install the AWS CDK:

sudo npm install -g aws-cdk

You can check the toolkit version with this command:

cdk --version

Now you are ready to create a virtualenv:

python3 -m venv .venv

Activate your virtualenv:

source .venv/bin/activate

Install the required dependencies:

pip install -r requirements.txt

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

cdk synth

If everything looks good, go ahead and deploy. This step will actually make changes to your AWS cloud environment.

cdk bootstrap
cdk deploy

To clean up, issue this command:

cdk destroy

To exit the virtualenv python environment:

deactivate

Useful commands

  • cdk ls List all stacks in the app
  • cdk synth Emit the synthesized CloudFormation template
  • cdk deploy Deploy this stack to your default AWS account/Region
  • cdk diff Dompare deployed stack with current state
  • cdk docs Open CDK documentation

This code has been tested and verified to run with AWS CDK 2.70.0 (build c13a0f1).
