AWS Instance

This is an module to creates a DC/OS AWS Instance.

If ami variable is not set. This module uses the mesosphere suggested OS which also includes all prerequisites.

If you choose to use your own AMI please make sure the DC/OS related prerequisites are met. Take a look at https://docs.mesosphere.com/1.11/installing/ent/custom/system-requirements/install-docker-RHEL/

EXAMPLE

module "dcos-master-instance" {
  source  = "terraform-dcos/instance/aws"
  version = "~> 0.1.0"

  cluster_name = "production"
  subnet_ids = ["subnet-12345678"]
  security_group_ids = ["sg-12345678"]
  hostname_format = "%[3]s-master%[1]d-%[2]s"
  ami = "ami-12345678"

  extra_volumes = [
    {
      size        = "100"
      type        = "gp2"
      iops        = "3000"
      device_name = "/dev/xvdi"
    },
    {
      size        = "1000"
      type        = ""     # Use AWS default.
      iops        = "0"    # Use AWS default.
      device_name = "/dev/xvdj"
    }
  ]
}
