Site-Specific DC/OS Terraform Module

This module was forked from Miguel's DC/OS Terraform code and modified to integrate with users who leveage Terraform remote state in their deployments and want to manage the VPC infrastructure on their own.

How To Use This Module

The module makes a few assumptions about your deployment:

1. The VPC is managed from remote state and has the following outputs:
   • vpc_id: a string which corresponds to aws_vpc.<name>.id
   • public_subnet_ids: an array which correspond to aws_subnet.<name>.id for your public subnets.
   • private_subnet_ids: an array which correspond to aws_subnet.<name>.id for your privatre subnets.
2. The remote state is stored in S3. The module requires these variable be set:

data "terraform_remote_state" "vpc" {
  backend     = "s3"
  environment = "${var.vpc_remote_state_terraform_environment}"

  config {
    bucket  = "${var.vpc_remote_state_s3_bucket}"
    key     = "${var.vpc_remote_state_s3_key}"
    region  = "${var.vpc_remote_state_s3_region}"
    profile = "${var.vpc_remote_state_aws_profile}"
  }
}

3. This module assumes you're using a SSH bastion host to access the VPC

To run this module, you can call it from your site-specific code base like this:

module "dcos" {
  source = "github.com/malnick/terraform-dcos/aws"

  vpc_remote_state_s3_bucket             = "<MY_COMPANY_BUCKET"
  vpc_remote_state_s3_key                = "<MY_VPC>/vpc.tfstate"
  vpc_remote_state_s3_region             = "<MY_REGION>"
  vpc_remote_state_aws_profile           = "<MY_AWS_PROFILE_NAME>" # See http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html
  vpc_remote_state_terraform_environment = "${terraform.env}" # See https://www.terraform.io/docs/state/environments.html
  bastion_host                           = "<MY_BASTION_HOST_IP>"
  bastion_user                           = "<MY_BASTION_HOST_USER" # Not the user for DC/OS

  key_name   = "<MY_KEY_NAME_FOR_DCOS_HOSTS>"
  aws_region = "<MY_VPC_REGION>"
  os         = "centos_7.2"
  owner      = "<MY_NAME>"
}

There is a slew of other configurations you can run to customize this module, please refer to the variables.tf for options.
