Service Connection in Azure using Terraform

Today we will learn to create service connection in Azure. Hello Everyone and Welcome to the series of Cloud Informative.

As we know Infrastructure as a Service (IaaS) allows us to create resources in the cloud like storage accounts, events and many more

Steps to Create a Service Connection in Azure

We will create the terraform module to implement the creation of a connection :

module
|________main.tf
|________variables.tf
|________providers.tf
|________terraform.auto.tfvars

Let’s start with the providers.tf file :

terraform {
  required_providers {

    azuredevops = {
      source  = "microsoft/azuredevops"
      version = "0.10.0"
    }
  }
  required_version = ">= 0.13"
}

provider "azuredevops" {
  personal_access_token = var.adotoken_VV
  org_service_url         = var.organization_service_url_VV
}

Here is the variables.tf file which contains all the variables to be utilise:

variable "adotoken_VV" {
  type        = string
  description = "Personal Access Token to create Service Connection"
}

variable "organization_service_url_VV" {
  type        = string
  description = "Organisation Service URL"
}

variable "azure_devops_project_VV" {
  type        = string
  description = "Name of Azure DevOps Project"
}

variable "azure_devops_build_definition_VV" {
  type        = string
  description = "Name of Azure DevOps Pipeline"
}

variable "name_VV" {
  type        = string
  description = "Common Name"
}

variable "service_principal_id_VV" {
  type        = string
  description = "ID of Service Principal"
}

variable "service_principal_key_VV" {
  type        = string
  description = "Key of Service Principal"
}

variable "tenant_id_VV" {
  type        = string
  description = "ID of Tenant"
}

variable "subscription_id_VV" {
  type        = string
  description = "ID of Subscription"
}

variable "subscription_name_VV" {
  type        = string
  description = "Name of Subscription"
}

And, this is our main.tf file which contains the main module :

locals {
  service_endpoint_name = var.name_VV
}

data "azuredevops_project" "project" {
  name = var.azure_devops_project_VV
}

resource "azuredevops_serviceendpoint_azurerm" "service_connection" {
  project_id                                    = data.azuredevops_project.project.id
  service_endpoint_name                     = local.service_endpoint_name
  service_endpoint_authentication_scheme = "ServicePrincipal"

  credentials {
    serviceprincipalid  = var.service_principal_id_VV
    serviceprincipalkey = var.service_principal_key_VV
  }
  azurerm_spn_tenantid      = var.tenant_id_VV
  azurerm_subscription_id   = var.subscription_id_VV
  azurerm_subscription_name = var.subscription_name_VV
}

We can also generate our terraform.auto.tfvars as per our requirement:

Like:

Name_of_Variable        = "Value"
