Playing with Terraform inside Azure Cloud Shell

May 29, 2020 #azure #cli #terraform #cloudshell

I noticed that terraform was one of the tools pre-configured in Azure Cloud Shell, so I decided to play around with it based on the Terraform Getting Started - Azure learning track.

I created a azuredeploy.tf file which would just create an Azure Resource Group named myResourceGroupT and Storage Account named terraformlabkjh20200529

kevin@Azure:~$ cat azuredeploy.tf
provider "azurerm" {
  version         = ">= 2.0"
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = "myResourceGroupT"
  location = "Central US"
}

resource "azurerm_storage_account" "example" {
  name                     = "terraformlabkjh20200529"
  resource_group_name      = azurerm_resource_group.example.name
  location                 = azurerm_resource_group.example.location
  account_tier             = "Standard"
  account_replication_type = "LRS"

  tags = {
    environment = "staging"
  }
}

Then after executing a terraform init and terraform apply, I could see the id values of the created resources in the partial output below.

azurerm_resource_group.example: Creation complete after 1s [id=/subscriptions/11111111-1111-4000-11111111111111111/resourceGroups/myResourceGroupT]
azurerm_storage_account.example: Creating...
azurerm_storage_account.example: Still creating... [10s elapsed]
azurerm_storage_account.example: Creation complete after 20s [id=/subscriptions/11111111-1111-4000-11111111111111111/resourceGroups/myResourceGroupT/providers/Microsoft.Storage/storageAccounts/terraformlabkjh20200529]

Apply complete! Resources: 2 added, 0 changed, 0 destroyed.

I also could find these id values from inspecting the terraform.tfstate file using a jq query of ".resources[].instances[].attributes.id"

kevin@Azure:~$ cat terraform.tfstate | jq ".resources[].instances[].attributes.id"
"/subscriptions/11111111-1111-4000-11111111111111111/resourceGroups/myResourceGroupT"
"/subscriptions/11111111-1111-4000-11111111111111111/resourceGroups/myResourceGroupT/providers/Microsoft.Storage/storageAccounts/terraformlabkjh20200529"

I did notice the terraform version was out of date inside Azure Cloud Shell.

kevin@Azure:~$ terraform --version
Terraform v0.12.25
+ provider.azurerm v2.12.0

Your version of Terraform is out of date! The latest version
is 0.12.26. You can update by downloading from https://www.terraform.io/downloads.html

But, then again, so is the version of the Azure CLI.

kevin@Azure:~$ az --version
azure-cli                          2.5.1 *

command-modules-nspkg              2.0.3

You have 2 updates available. Consider updating your CLI installation with 'sudo apt-get update && sudo apt-get install --only-upgrade -y azure-cli'. Detailed instructions can be found at https://aka.ms/doc/UpdateAzureCliApt

A simple example, but now I can add Terraform experience to my resume. :)
