HashiCorp Consul Service on Azure (HCS) Terraform Provider

Requirements

• Terraform >= 0.12.x
• Go >= 1.15

Building The Provider

1. Clone the repository
2. Enter the repository directory
3. Build the provider using the make dev command

Adding Dependencies

This provider uses Go modules. Please see the Go documentation for the most up to date information about using Go modules.

To add a new dependency github.com/author/dependency to your Terraform provider:

go get github.com/author/dependency
go mod tidy

Then commit the changes to go.mod and go.sum.

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (see Requirements above).

To compile the provider, run go install. This will build the provider and put the provider binary in the $GOPATH/bin directory.

To generate the latest models for the HCS Custom Resource Provider actions, run:

make generate-hcs-ama-api-spec-models

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create real resources, and often cost money to run.

$ make testacc

Generating Docs

From the root of the repo run:

go generate && go mod tidy

Using the provider

Please see the docs for details about a particular resource. Below is a complex example that leverages the Azure Terraform provider and creates a federation of two HCS clusters.

// Configure the provider
provider "hcs" {}

provider "azurerm" {
  features {}
}

// If you have not already done so, accept the HCS Marketplace agreement
data "hcs_plan_defaults" "hcs_plan" {}

resource "azurerm_marketplace_agreement" "hcs_marketplace_agreement" {
  publisher = data.hcs_plan_defaults.hcs_plan.publisher
  offer     = data.hcs_plan_defaults.hcs_plan.offer
  plan      = data.hcs_plan_defaults.hcs_plan.plan_name
}

// Create the Resource Group for the primary cluster
resource "azurerm_resource_group" "primary" {
  name     = "hcs-tf-federation-primary-rg"
  location = "westus2"
}

// Create the primary cluster
resource "hcs_cluster" "primary" {
  resource_group_name      = azurerm_resource_group.primary.name
  managed_application_name = "hcs-tf-federation-primary"
  email                    = "[email protected]"
  cluster_mode             = "production"
  min_consul_version       = "v1.9.0"
  vnet_cidr                = "172.25.16.0/24"
  consul_datacenter        = "hcs-tf-federation-example"
}

// Create a federation token
data "hcs_federation_token" "fed" {
  resource_group_name      = hcs_cluster.primary.resource_group_name
  managed_application_name = hcs_cluster.primary.managed_application_name
}

// Create the Resource Group for the secondary cluster
resource "azurerm_resource_group" "secondary" {
  name     = "hcs-tf-federation-secondary-rg"
  location = "eastus"
}

// Create the secondary cluster using the federation token from above
resource "hcs_cluster" "secondary" {
  resource_group_name      = azurerm_resource_group.secondary.name
  managed_application_name = "hcs-tf-federation-secondary"
  email                    = "[email protected]"
  cluster_mode             = "production"
  min_consul_version       = "v1.9.0"
  vnet_cidr                = "172.25.17.0/24"
  consul_datacenter        = "hcs-tf-federation-secondary"
  consul_federation_token  = data.hcs_federation_token.fed.token
}
