• Create a new git repository (git init)
• Add the following to your .gitignore file:

.env
.terraform
*.tfstate*

• Commit your .gitignore file (git add .gitignore; git commit)
• Add your assigned remote (git remote add origin master [email protected]...)
• Push your branch to the remote (git push -u origin master)

Pro tip! Add the terraform syntax highlighter for your favorite editor!

NB! In order to complete this lab you will need a .env file with your assigned Azure credentials! If you have not yet got it, please ask your instructor.

In order to get started with Terraform we need the following parts:

• One or more Terraform providers. For this workshop we will be using the azurerm provider.
• A remote state backend for storing the Terraform state.
• Resources (the items) that Terraform should set up.

Terraform is very relax when it comes to file structure. It dosn't require any main methods or file conventions as it creates a depencendy graph dynamically. However it requires all files to be at the root folder (unless you are using modules).

Start by create a folder named terraform in your git repo; inside this the following files should be present. Just create empty files and we'll fill them with content as we go.

• variables.tf
• provider.tf
• main.tf

This file will hold our Terraform variables. As the name suggests these can be re-used accross the Terraform setup and they can have different values for different environments.

All variables needs to be declared and we recommend that you put them in this file in order to keep track of them an better re-usability.

NB! Terraform favours underscore _ when seperating words in variables like this: my_awesome_variable. Try to adheare to this to make the code more uniform.

Variables are declared like this:

variable "my_variable" {}

This will create an unitialized variable which means that you need to assign it a value at runtime in order for Terraform to procede.

If you want to hava a default value you can do it like this:

value "my_variable" {
  default = "This is a default value"
}

Variables are strings by default but Terraform supports a variety of other data types.

Go ahead and add the following variables to your variables.tf file now:

variable "user_id" {}
variable "azure_location" {}
variable "azure_resource_group" {}
variable "azure_client_id" {}
variable "azure_client_secret" {}
variable "azure_tenant_id" {}
variable "azure_subscription_id" {}

As you can see they have no default value. That is becuase we never want to hard code credentials or other sensitive information inside our configuration, these should be kept secret and injected using environment variables.

As mentioned we will be using the azurerm Terrafrom provider for this workshop. The provider configuration connects to the infrastructure and makes it possible for Terraform to set up, modify and delete resources on your behalf.

The provider defintion looks like this:

provider "azurerm" {
  subscription_id            = "${var.azure_subscription_id}"
  client_id                  = "${var.azure_client_id}"
  client_secret              = "${var.azure_client_secret}"
  tenant_id                  = "${var.azure_tenant_id}"
  version                    = "v1.33.0"
  skip_provider_registration = true
}

As you can see this corresponds to the variables we have set up on our variables.tf file.

Now let's add something to our main.tf file so we can verify that our setup is working.

data "azurerm_resource_group" "ws" {
  name = var.azure_resource_group
}

This won't actually create something, this is a Terraform data source which is a reference to an existing resource. data
