## Terraform Consul Load Testing # How to use 1. Build an image with the desired Consul version and a loadtest 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, here is 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" ## This is found from building the image in packer/loadtest-ami test_server_ami = "ami-0ad7711e837ebe166" cluster_name = "ctest" test_public_ip = "true" instance_type = "t2.micro" ami_owners = ["******"] ## This is found from building the image in packer/consul-ami consul_ami_id = "ami-016d80ff5472346f0" ``` 4. AWS Variables are set off of environment variables. Make sure to export nessecary variables [shown here](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#environment-variables). 5. Run `terraform plan -var-file=vars.tfvars`, and then `terraform apply -var-file=vars.tfvars` when ready. 6. Upon completion k6 should run and push metrics to desired Datadog dashboard. # Customization All customization for infrastructure that is available can be found by looking through the `variables.tf` file. However, if customization of tests is desired then the `start-k6.sh` leverages user-data to place a `puts_script.js` onto the loadtest servers for k6 to run. This can be customized. # How to SSH After `terraform apply` is ran Terraform should create a `keys/` directory which will give access to all instances created.
