CDK Locust

This CDK project deploys Locust, an Open Source load tesing framework using AWS CDK. This uses CDK in Typescript and is inspired by the CDK Python Locust project.

The this will deploy:

• Amazon VPC with NAT Gateways
• ECS on Fargate with two services:
• Locust Primary - Single Primary (master) container, behind an ALB
• Locust Workers - Multiple workers (slave) containers (10 by default)
• VPC Security Group permissions - all necessary secgroups to allow primary/worker communication
• IAM roles and policies required for running the AWS services
• AWS CloudMap - for service discovery between primary and workers
• Locust Containers - built as an asset by CDK from the DockerHub container and stored in ECR
