Provisioning Azure Storage Blob With Terraform

In this post, I will show you how to deploy an Azure storage blob using Terraform. This will save you time wasted clicking through the Azure portal, which is the best part of Infrastructure-as-code. Difficulty level is 2/10.

So, let’s get started.

Prerequisite:

• Authentication with AZ login

• Terraform installed

Authentication With AZ Login

This is simply granting your terminal authenticated access to your Azure account, and it takes only two words; see below.

Az login

Once you type that in and hit enter, it launches your web browser, where you can enter your Azure portal credentials if you are not already logged in to Azure on that browser.

You are good to go if you see a screen like this on your browser; otherwise, double-check your login credentials.

Terraform installed

Follow the documentation provided by Hashicorp to install Terraform on your local machine.

Terraform Code

Alright, now to the main deal. You can clone my GitHub repo for this.

Below is the Terraform code that goes into the main.tf file.

#creates a resource group for the services below
resource "azurerm_resource_group" "demo-resource-group" {
  name     = var.resource_group_name
  location = var.resource_group_geolocation
}

#creates a storage account for your containers
resource "azurerm_storage_account" "demo-storage-account-tf" {
  name                     = var.storage_account_name
  resource_group_name      = azurerm_resource_group.demo-resource-group.name
  location                 = azurerm_resource_group.demo-resource-group.location
  account_tier             = "Standard"
  account_replication_type = "LRS"
}

#creates a container to store your content
resource "azurerm_storage_container" "demo-storage-container-tf" {
  name                  = var.storage_container_name
  storage_account_name  = azurerm_storage_account.demo-storage-account-tf.name
  container_access_type = "private"
}

#uploads a file/blob into the above created container
resource "azurerm_storage_blob" "my-file-demo" {
  name                   = "my-file-name-and-its.extention"
  storage_account_name   = azurerm_storage_account.demo-storage-account-tf.name
  storage_container_name = azurerm_storage_container.demo-storage-container-tf.name
  type                   = "Block"
  source                 = "path-to-my-file"
}

Code for the providers.tf file.

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "3.100.0"
    }
  }
}

provider "azurerm" {
  features {}
}

Code for the variables.tf file.

variable "resource_group_name" {
  default = "myresourcegroupname"
}

variable "resource_group_geolocation" {
  default = "West Europe"
}


#your storage account name has to be unique across all of Azure
variable "storage_account_name" {
  default = "myuniqueaccountname"
}

variable "storage_container_name" {
  default = "mycontainername"
}
