# 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](../packer).
|
|
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](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#environment-variables).
|
|
6. Run `terraform init` once to setup the working directory.
|
|
7. Run `terraform plan -var-file=vars.tfvars`, and then `terraform apply -var-file=vars.tfvars` when ready.
|
|
8. 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"
|
|
vpc_allwed_ssh_cidr = "0.0.0.0/0"
|
|
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"
|
|
````
|
|
|
|
Note that `vpc_allwed_ssh_cidr` must be set to allowed the test server to be accessible from the
|
|
machine running the load test, e.g., "0.0.0.0/0" (It is disabled by default).
|
|
|
|
## 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]`
