Examples to launch Aviatrix controller using terraform.

Aviatrix - Terraform Modules

Description

These Terraform modules allow you to build Aviatrix Controllers and prepare accounts for connecting to an existing Aviatrix Controller.

NOTE: It is highly recommended to have the following modules in a directory separate from the rest of your Terraform pipeline. These modules only need to be run once to build the Controller and dependent resources.

Available Modules

Module	Description	Prerequisites
aviatrix-controller-iam-roles	Builds the IAM roles required for Aviatrix to connect with this AWS account	None
aviatrix-controller-build	Builds the controller in an AWS VPC	Existing VPC, Public subnet, An AWS Key Pair, IAM roles created
aviatrix-controller-initialize	Initializes the Controller (Upgrade, set admin e-mail, set admin password).	Aviatrix Controller

Basic Usage

module "<<name>>" {
  source = "github.com/AviatrixSystems/terraform-modules.git/<<module-name>>"
  var1   = "<<value1>>"
}

Building a Controller and Initializing it

The Aviatrix provider requires the Controller to be up and running before it can operate, the initialization can be separated from building the Controller:

1. Create the IAM roles

createIAM.tf

provider "aws" {
  <<< your credentials and region >>>
}

module "iam_roles" {
  source = "github.com/AviatrixSystems/terraform-modules.git//aviatrix-controller-iam-roles?ref=terraform_0.12"
}

Execute

> cd iam
> terraform init
> terraform apply
> cd ..

2. Build the Controller

build.tf

provider "aws" {
  <<< your credentials and region >>>
}

module "aviatrixcontroller" {
  source      = "github.com/AviatrixSystems/terraform-modules.git//aviatrix-controller-build?ref=terraform_0.12"
  vpc         = "<<< your VPC ID >>>"
  subnet      = "<<< your public Subnet ID >>>"
  keypair     = "<<< your EC2 key pair name >>>"
  ec2role     = "aviatrix-role-ec2"
  name_prefix = "<<< unique for specified controller >>>"
}

output "controller_private_ip" {
  value = module.aviatrixcontroller.private_ip
}

output "controller_public_ip" {
  value = module.aviatrixcontroller.public_ip
}

Execute

> cd build
> terraform init
> terraform apply
> terraform output | sed -ne 's/\(.*\) = \(.*\)/\1="\2"/p' > ../aviatrix_controller.tfvars
> cd ..

3. Initialize the Controller

init.tf

provider "aws" {
  <<< your credentials and region >>>
}

variable "controller_private_ip" {}

variable "controller_public_ip" {}

module "aviatrix_controller_init" {
  source              = "github.com/AviatrixSystems/terraform-modules.git//aviatrix-controller-initialize?ref=terraform_0.12"
  admin_email         = "<<< your administrator email address >>>"
  admin_password      = "<<< your new admin password >>>"
  private_ip          = var.controller_private_ip
  public_ip           = var.controller_public_ip
  access_account_name = "<<< your account name mapping to your AWS account in the Aviatrix Controller >>>"
  aws_account_id      = "<<< your aws account id >>>"
  vpc_id              = "<<< your vpc id here >>>"
  subnet_id           = "<<< your public subnet id >>>"
  customer_license_id = "<<< your customer license id (optional) >>>"   
}

output "lambda_result" {
  value = "${module.aviatrix_controller_init.result}"
}

Execute

> cd init
> terraform init
> terraform apply -var-file=../aviatrix_controller.tfvars

Putting it all together

You can run each of these steps in a single .tf file. Here is an example:

provider "aws" {
  <<< your credentials and region >>>
}

data "aws_caller_identity" "current" {}

module "aviatrix-iam-roles" {
  source = "github.com/AviatrixSystems/terraform-modules.git//aviatrix-controller-iam-roles?ref=terraform_0.12"
}

module "aviatrix-controller-build" {
  source  = "github.com/AviatrixSystems/terraform-modules.git//aviatrix-controller-build?ref=terraform_0.12"
  vpc     = "<<< VPC ID >>>"
  subnet  = "<<< Subnet ID >>>"
  keypair = "<<< Keypair name >>>"
  ec2role = module.aviatrix-iam-roles.aviatrix-role-ec2-name
}

provider "aviatrix" {
  username      = "admin"
  password      = module.aviatrix-controller-build.private_ip
  controller_ip = module.aviatrix-controller-build.public_ip
}

module "aviatrix-controller-initialize" {
  source              = "github.com/AviatrixSystems/terraform-modules.git//aviatrix-controller-initialize?ref=terraform_0.12"
  admin_password      = "<<< new admin password >>>"
  admin_email         = "<<< admin email address >>>"
  private_ip          = module.aviatrix-controller-build.private_ip
  public_ip           = module.aviatrix-controller-build.public_ip
  access_account_name = "<<< account name for this AWS account >>>"
  aws_account_id      = data.aws_caller_identity.current.account_id
  vpc_id              = module.aviatrix-controller-build.vpc_id
  subnet_id           = module.aviatrix-controller-build.subnet_id
}

output "result" {
  value = module.aviatrix-controller-initialize.result
}

output "controller_private_ip" {
  value = module.aviatrix-controller-build.private_ip
}

output "controller_public_ip" {
  value = module.aviatrix-controller-build.public_ip
}
