This Terraform module will create a single server within each availability zone in each ProfitBricks location.

Create a Terraform config file. For example, main.tf.

module "loadtest" {
  source = "github.com/stackpointcloud/tf_profitbricks_loadtest"

  locations = [ "us/las", "us/ewr", "de/fra", "de/fkb" ]
  availability_zones = [ "ZONE_1", "ZONE_2" ]
  cores = 1
  ram = 1024
  disk_size = 5
  image_alias = "ubuntu:latest"
  private_ssh_key_path = "/path/to/.ssh/id_rsa"
  public_ssh_key_path = "/path/to/.ssh/id_rsa.pub"
  registry_host          = "hub.private.com"
  registry_host_username = "docker_username"
  registry_host_password = "docker_password"
}

output "server_ips" {
  value = "${module.loadtest.server_ips}"
}

Initialize and run Terraform:

terraform init
terraform plan
terraform apply

Docker:

docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem -H=[IP_ADDRESS]:2376 info

Docker TLS authentication can also be set through environment variables.

export DOCKER_CERT_PATH=$PWD
export DOCKER_TLS=1
export DOCKER_TLS_VERIFY=1

docker -H=[IP_ADDRESS]:2376 info
