My example Pipeline consists of snippets from this GitHub, Validate:- To Validate my Terraform code, if validation fails the pipeline fails (consists of Terraform init & validate), Deploy:- if Validation is successful, it moves to next stage of pipeline which is Deploying the Terraform code to deploy required Azure Resources (consists of Terraform plan & deploy), Throughout the Pipeline, notice my reference to the previously created Storage Account, Resource Group and container for the Terraform state file along with the newly created SPN? Check out my other blog posts also. When you create a Service Principal then from an RBAC perspective it will, by default, have the Contributor role assigned at the subscription scope level. e.g.. data.azurerm_client_config.main.service_principal_object_id. You will often see examples of Terraform resource types where the service principal is created manually. Terraform should have created an application, a service principal and set the given random password to the service principal. Azure Provider: Authenticating using the Azure CLI. We have reached the end of the lab. The command has a --scope switch that defaults to the subscription but can be set to another scope point such as a resource group or an individual resource.

(extraction below), Once you configure & save the above pipeline, you will see it beginning to run and can review both stages, After a few minutes, the build Pipeline will run through and if both stages are successful you will see similar to below, Reviewing the job, you will see a more thorough breakdown of the tasks, Selecting for example plan, you will see what Azure Resources are planned to be deployed, Reviewing inside the Azure Portal, you will see the newly created Resource Group & Storage Account. Thank you for taking your time out to pen down this blog. Using service principals is an easy and powerful way of managing multi-tenanted environments when the admins are working in a centralised Terraform environment. Terraform will use the service principal to authenticate and get access to your Azure subscription. A Service Principal is like a service account you create yourself, where a Managed Identity is always linked to an Azure Resource. A Service Principal (SPN) is considered a best practice for DevOps within your CI/CD pipeline. subscription_id - (Required) The subscription GUID. For example, by adding the following lines to a .bashrc file: If you are using environment variables then the provider block should be empty: Note that this approach is not as effective if you are moving between terraform directories for different customer tenancies and subscriptions, as you need to export the correct variables for the required context, but it does have the benefit of not having the credentials visible in one of the *.tf files. Go to your Azure Devops Project, hit the Cog icon, go the Service connections; Click on the New service connection button (top right) Select Azure Resource Manager — Service Principal (automatic) Select your Subscription and Resource Group, check the Grant access permission to all pipelines, and Save it; 4 — Create the CI Pipeline Git repo Using aliases can be of use in a customer environment where they want to configure a deployment across multiple subscriptions or clouds. An alternative is to make use of the Terraform VM discussed towards the bottom of the lab. Blueprint write and delete actions are prohibited.

Change ). Deploying resources already into Azure; you probably already have came across using Azure DevOps, it is a hosted service by Microsoft that provides an end-to-end DevOps toolchain for developing and deploying software, along with this – it is a hosted service to deploy CI/CD Pipelines, There are some prior requirements you need to complete before we can get deploying Terraform using Azure DevOps. The project in this tutorial will interact with Azure. Post was not sent - check your email addresses!

In this deployment, I want to store the state file remotely in Azure; I will be storing my state file in a Storage Account container called:- tfstatedevops, Lets deploy the required storage container called tfstatedevops in Storage Account tamopstf inside Resource Group tamopstf. This is done within “Manage Service Principal”, Settings -> Properties and change Name as below. If you are creating resource groups (and standard resources within them) then a Terraform service principal with the standard Contributor role assigned at the subscription level is the most common configuration you will see. I’m seeing the same issue. For most applications you would remove that and then assign a more limited RBAC role and scope assignment, but this default level is ideal for Terraform provisioning. Using a Service Principal, also known as SPN, is a best practice for DevOps or CI/CD environments and is one of the most popular ways to set up a remote backend and later move to CI/CD, such as Azure DevOps.. First, we need to authenticate to Azure. ( Log Out /  However the remaining labs really are based on Windows 10 users having enabled the Windows Subsystem for Linux (WSL) and do make use of Bash scripting at points. Service principals work really well in a multi-tenanted environment as the service principal authentication details can sit directly in the relevant terraform directory so that it is easy to define the target subscription and tenancy and tightly connect it with the other infrastructure definitions. Service principal is created in Azure AD, has a unique object ID (GUID) and authenticate via certificates or secret. missed something?

We want to allow some of those Microsoft.Authorization actions. Lists all AD service principals in a tenant. You create a service principal for Terraform with the respective rights needed on Azure (it might be a highly privileged service principal depending on what you deploy via Terraform) and configure Azure DevOps to use this service principal every time … Thanks for the blog! So by using TerraForm, you gain a lot of benefits, including being able to manage all parts of your infrastructure using HCL languages to make it rather easy to manage. Hi, Granting consent requires a few REST API calls.

It was really useful. Follow the portal steps to navigate to the API Permissions dialog and then click on the button to grant consent. You will have already been using the az and terraform executables locally. Lets have a look at each of these requirements; I will include an example of each and how you can configure. Once the node build is done I can login using these credentials. When deploying Terraform there is a requirement that it must store a state file; this file is used by Terraform to map Azure Resources to your configuration that you want to deploy, keeps track of meta data and can also assist with improving performance for larger Azure Resource deployments. which tenancy and subscription). Here are a few: Searching on "terraform azure service principal" takes you to https://www.terraform.io/docs/providers/azurerm/authenticating_via_service_principal.html. A service connection enables you to hook-up the AzureDevOps project to the magical fairy-cloud of Azure. In a previous article I talked about how you need to set the following variables in your pipeline so that Terraform can access Azure:ARM_CLIENT_ID = This is the application id from the service principal in Azure AD; ARM_CLIENT_SECRET = This is the secret for the service principal in Azure AD In the 2.0 changes, the azurerm_client_config has depreciated service_principal Note that there does not appear to be a CLI command to grant admin consent for the Default Directory. In this challenge you will create a service principal called terraform-labs--sp. In these scenarios, an Azure Active Directory identity object gets created.
