Terraform Consul Load Testing

How to use

1. Build an image with the desired Consul version and a load test image in the Packer folder here.
2. Create your own vars.tfvars file in this directory.
3. Place the appropriate AMI IDs in the consul_ami_id and test_server_ami variables. If no AMI ID is specified it will default to pulling from latest.
4. Set either consul_version or consul_download_url. If neither is set it will default to utilizing Consul 1.9.0
5. AWS Variables are set off of environment variables. Make sure to export necessary variables shown here.
6. Run terraform plan -var-file=vars.tfvars, and then terraform apply -var-file=vars.tfvars when ready.
7. Upon completion k6 should run and push metrics to the desired Datadog dashboard.

An example of a vars.tfvars :

vpc_name             = "consul-test-vpc"
vpc_cidr             = "11.0.0.0/16"
public_subnet_cidrs  = ["11.0.1.0/24", "11.0.3.0/24"]
private_subnet_cidrs = ["11.0.2.0/24"]
vpc_az               = ["us-east-2a", "us-east-2b"]
test_instance_type   = "t2.micro"
test_server_ami      = "ami-0ad7711e837ebe166"
cluster_name         = "ctest"
test_public_ip       = "true"
instance_type        = "t2.micro"
ami_owners           = ["******"]
consul_ami_id        = "ami-016d80ff5472346f0"

Customization

All customization for infrastructure that is available can be found by looking through the variables.tf file.

How to SSH

After terraform apply is run Terraform should create a keys/ directory which will give access to all instances created. For example, ssh -i "keys/[cluster-name]-spicy-banana.pem" ubuntu@[IPADDRESS]
