Deploy Azure Data Services with Terraform

Terraform-based deployment of almost all Azure Data Services (default deployment settings are in the parenthesis):

  • Azure Service Bus (Standard, namespace,topic,subscription, auth. rules)
  • Azure Data Lake Storage (ZRS, Hot, Secured, StandardV2)
  • Azure Data Factory (w/Git or without)
  • Azure Data Factory linked with Data Lake Storage
  • Azure Data Factory Pipeline
  • Azure DataBricks WorkSpace (Standard)
  • Azure EventHub (Standard, namespace)
  • Azure Functions (Dynamic, LRS storage, Python, w/App.Insights or without)
  • Azure Data Explorer (Kusto, Standard_D11_v2, 2 nodes)
  • Azure Analysis Server (backup-enabled, S0, LRS, Standard)
  • Azure Event Grid (domain, EventGridSchema)

Properties and content

  • 831 strings in total
  • Written about 1 year ago, updated a day ago to fix deprecated expressions
  • Tested with the latest Terraform 0.13.2 and Azure provider 2.27.0 (in fact, works fine with >=0.12 and Azure provider >= 1.35)
  • – provider authentication and version settings
  • – a desired Azure infrastructure
  • terraform.tfvars – controls deployment settings
  • – variables list
  • – outputs useful information

Deployment settings (excerpt)

# What should be deployed?
servicebus       = true  # Azure Service Bus
datafactory      = true  # Azure Data Factory
datafactory_git  = false # Enable GIT for Data Factory? (don't forget to set Git settings in the Data Factory section)
databricks       = true  # Azure DataBricks
eventhub         = true  # Azure EventHub
functions        = true  # Azure Functions 
functions_appins = true  # Integrate App.Insights with Azure Functions?
eventgrid        = true  # Azure EventGrid
kusto            = true  # Azure Data Explorer (kusto)
analysis         = true  # Azure Analysis Server

Resource block (excerpt)

resource "azurerm_function_app" "rlmvp-svc-function-appins" {
  count                      = var.functions == "true" && var.functions_appins == "true" ? 1 : 0
  name                       = "${var.prefix}function${random_string.rndstr.result}"
  location                   = var.az_region
  resource_group_name        =
  app_service_plan_id        = azurerm_app_service_plan.rlmvp-svc-appplan[count.index].id
  storage_account_name       = azurerm_storage_account.rlmvp-svc-storacc[count.index].name
  storage_account_access_key = azurerm_storage_account.rlmvp-svc-storacc[count.index].primary_access_key
  # storage_connection_string = azurerm_storage_account.rlmvp-svc-storacc[count.index].primary_connection_string (deprecated; works though)
  app_settings = {
    "FUNCTIONS_WORKER_RUNTIME"       = var.az_funcapp_runtime
    "APPINSIGHTS_INSTRUMENTATIONKEY" = azurerm_application_insights.rlmvp-svc-appins[count.index].instrumentation_key
  tags = var.az_tags

Usage guide

  • Open the terraform.tfvars file
  • Indicate the “What Should Be Deployed?” section
  • Use true/false to set your desired configuration
  • Check or change Azure services settings in the appropriate sections (naming convention (prefix/suffix), location, SKUs and etc.)
  • Run terraform init to get required Terraform providers
  • Run terraform plan to initiate pre-deployment check
  • Run terraform apply to start a deployment
  • (optional) terraform destroy to delete Azure resources


  • The script uses Service Principal authentication, so define the subscription ID, client ID, tenand ID and principal secret in the (or use another authentication type – Managed Identity, if your CI is running on Azure VMs, for instance)
  • If you are going to deploy Analysis Server (enabled, by default), provide valid Azure AD user(s) UPN(s) to set them as administrators of Analysis Server (az_ansrv_users variable, file – terraform.tfvars)

Announcing my GitHub repositories

Howdy, I decided to share some scripts and configuration files via GitHub. This approach has many advantages – user-friendly code (easy to read, easy to use), you can commit changes via pull requests, easier to update the code, you can follow me to instantly receive updates.

Terraform and Packer configurations

  • terraform-k8s-aks: automates Azure Kubernetes and Container Registry services deployment. See the blog post.
  • terraform-globalazure-2019: source code from my session at Global Azure BootCamp 2019 Russia. The main configuration file automates deployment of VMs, availability set, load balancer, NSGs and registers VMs with Azure DevOps Deployment Group to make possible CD.
  • packer-iis: packer sample json to create a custom image in Azure. See the blog post.

Azure and Kubernetes


I will keep this post updated. If new repos added, I’ll describe them here as well. Thanks for following. Cheers.
