Terraform AWS Locust

This project uses Terraform to provision AWS resources for a Locust load testing setup. It includes the creation of VPC, subnets, security groups, IAM roles, and EC2 instances for running Locust in master-worker mode. Prerequisites

  • Terraform v0.12 or later
  • AWS account with necessary permissions
  • AWS CLI configured with access key and secret Configuration

Create a terraform.tfvars file in the root directory of the project. This file will contain the necessary variables for the Terraform configuration. Here's an example of what this file might look like:

aws_region = "us-east-1"
aws_ami = "ami-0fc5d935ebf8bc3bc" # Ubuntu 22.04 us-east-1
vpc_name = "vpc-locust-terraform"
vpc_cidr = "10.0.0.0/16"
public_subnet_cidr = "10.0.1.0/24"
public_subnet_bckp_cidr = "10.0.2.0/24"
private_subnet_cidr = "10.0.3.0/24"
master_instance_type = "t2.micro"
workers_instance_type = "t3.small"
key_name = "my-key-pair"
workers_count = 3

Please replace the values with your own. The key_name should be the name of an existing EC2 Key Pair in your AWS account. Running the Project

  1. Initialize Terraform: terraform init

  2. Plan the deployment: terraform plan

  3. Apply the configuration: terraform apply

After running terraform apply, Terraform will output the load balancer dns. You can use this to access the Locust web interface.

Allow up to 5 minutes to instances run scripts after terraform apply is complete. After this you should can access via ALB dns.

  1. Cleaning Up

To destroy the resources created by this project, run: terraform destroy

This will remove all resources created by Terraform in this project.
