Terraform azure provider example

Writing Custom Providers

You can use Azure Terraform modules to create reusable, composable, and testable components. Terraform modules incorporate encapsulation that's useful in implementing infrastructure as code processes.

It's important to implement quality assurance when you create Terraform modules. Unfortunately, limited documentation is available to explain how to author unit tests and integration tests in Terraform modules. This tutorial introduces a testing infrastructure and best practices that we adopted when we built our Azure Terraform modules. We looked at all the most popular testing infrastructures and chose Terratest to use for testing our Terraform modules.

Terratest is implemented as a Go library. Terratest provides a collection of helper functions and patterns for common infrastructure testing tasks, like making HTTP requests and using SSH to access a specific virtual machine. The following list describes some of the major advantages of using Terratest:. This hands-on article is platform-independent.

In this tutorial, you create a Terraform module that provisions a static webpage by uploading a single HTML file to an Azure Storage blob. This module gives users from around the world access to the webpage through a URL that the module returns.

First, create a new folder named staticwebpage under your GoPath src folder. The overall folder structure of this tutorial is shown in the following example. The static webpage module accepts three inputs. The inputs are declared in. As we mentioned earlier in the article, this module also outputs a URL that's declared in. Terratest is designed for integration tests.

For that purpose, Terratest provisions real resources in a real environment. Sometimes, integration test jobs can become exceptionally large, especially when you have a large number of resources to provision. The logic that converts storage account names that we refer to in the preceding section is a good example.

But, we don't really need to provision any resources. We only want to make sure that the naming conversion logic is correct. Thanks to the flexibility of Terratest, we can use unit tests.

Unit tests are local running test cases although internet access is required. Unit test cases execute terraform init and terraform plan commands to parse the output of terraform plan and look for the attribute values to compare.

The rest of this section describes how we use Terratest to implement a unit test to make sure that the logic used to convert storage account names is correct. First, we use an empty HTML file named. The file. The logic is shown here:. The major component is the implementation of the unit tests in. In the body of the unit test, we have a total of five cases that are defined in variable testCases key as input, and value as expected output.Terraform provides an easy way to define, preview, and deploy cloud infrastructure by using a simple templating language.

This article describes the necessary steps to use Terraform to provision resources in Azure. To learn more about how to use Terraform with Azure, visit the Terraform Hub. For Terraform specific support, please reach out to Terraform directly using one of their community channels:.

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use the Cloud Shell preinstalled commands to run the code in this article without having to install anything on your local environment. Terraform is installed by default in the Cloud Shell. If you choose to install Terraform locally, complete the next step, otherwise continue to Set up Terraform access to Azure. To install Terraform, download the appropriate package for your operating system into a separate install directory.

The download contains a single executable file, for which you should also define a global path. For instructions on how to set the path on Linux and Mac, go to this webpage. For instructions on how to set the path on Windows, go to this webpage. Verify your path configuration with the terraform command. A list of available Terraform options is shown, as in the following example output:.

The service principal grants your Terraform scripts to provision resources in your Azure subscription. If you have multiple Azure subscriptions, first query your account with az account list to get a list of subscription ID and tenant ID values:. To use a selected subscription, set the subscription for this session with az account set. Now you can create a service principal for use with Terraform. Use az ad sp create-for-rbacand set the scope to your subscription as follows:.

Make a note of the appId and password. To configure Terraform to use your Azure AD service principal, set the following environment variables, which are then used by the Azure Terraform modules. You can also set the environment if working with an Azure cloud other than Azure public. Save the file and then initialize the Terraform deployment.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Further usage documentation is available on the Terraform website. If you wish to work on the provider, you'll first need Go installed on your machine version 1.

To compile the provider, run make build. The majority of tests in the provider are Acceptance Tests - which provisions real resources in Azure. It's possible to run the entire acceptance test suite by running make testacc - however it's likely you'll want to run a subset, which you can do using a prefix, by running:.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I have an existing resource group on Azure with a VM running on it and have been playing around with Terraform to try and import the resource to my state file.

I have set up a skeleton file, and as far as my understanding is once I import TF should populate this with the values on my resource group in Azure. It looks like you need to fix your script file first - azurerm isn't a valid resource name, did you mean:.

You also need to tell terraform which resource in your script it maps to:. More information about this please refer to this link.

Looking into the Azure provider source code I found out that you need to enter the full URL to the Azure resource - like this:. Learn more.

This will find and import the specified resource into your Terraform state, allowing existing infrastructure to come under Terraform management without having to be initially created by Terraform.

The ADDR specified is the address to import the resource to. Please see the documentation online for resource addresses. The ID is a resource-specific ID to identify that resource being imported. Please reference the documentation for the resource type you're importing to determine the ID syntax to use. It typically matches directly to the ID that the provider uses.

The current implementation of Terraform import can only import resources into the state. It does not generate configuration. A future version of Terraform will also generate configuration. Because of this, prior to running terraform import it is necessary to write a resource configuration block for the resource manually, to which the imported object will be attached.

This command will not modify your infrastructure, but it will make network requests to inspect parts of your infrastructure relevant to the resource being imported. Defaults to the "-state-out" path with ". Set to "-" to disable backup. Defaults to pwd. If no config files are present, they must be provided via the input prompts or env vars. This is used for specifying aliases, such as "aws.

Defaults to the normal provider prefix of the resource being imported.This example is built around the Virtual Machine Extension found in the windows-client module documented below - which demonstrates binding a Windows Virtual Machine to an Active Directory Domain. For the purposes of this example we create an Active Directory Domain, since it's easier to demonstrate - however you can achieve the same thing with an existing Active Directory Domain. In order to run this example you'll need some kind of credentials configured - either a Service Principal or to be logged into the Azure CLI.

You can find out more about this on the Azure Provider overview page. This will take around 20m to provision - once completed you should see the Public IP Address of the Windows Client machine which is bound to the Active Directory Domain :. Skip to content.

You build Terraform templates in a human-readable format that create and configure Azure resources in a consistent, reproducible manner. This article shows you how to create a complete Linux environment and supporting resources with Terraform. You can also learn how to install and configure Terraform. For Terraform specific support, please reach out to Terraform directly using one of their community channels:.

The Terraform section of the community portal contains questions, use cases, and useful patterns. For provider-related questions please visit the Terraform Providers section of the community portal. Let's go through each section of a Terraform template. You can also see the full version of the Terraform template that you can copy and paste.

The provider section tells Terraform to use an Azure provider. If you create environment variables for the values or are using the Azure Cloud Shell Bash experienceyou don't need to include the variable declarations in this section.

The following section creates a resource group named myResourceGroup in the eastus location:. The following section creates a virtual network named myVnet in the The following section creates a subnet named mySubnet in the myVnet virtual network:. Network Security Groups control the flow of network traffic in and out of your VM. The following section in a Terraform template creates a virtual NIC named myNIC connected to the virtual networking resources you've created:.

To store boot diagnostics for a VM, you need a storage account.

These boot diagnostics can help you troubleshoot problems and monitor the status of your VM. The storage account you create is only to store the boot diagnostics data. As each storage account must have a unique name, the following section generates some random text:. Now you can create a storage account. The following section creates a storage account, with the name based on the random text generated in the preceding step:.

The final step is to create a VM and use all the resources created. The latest Ubuntu With your Terraform template created, the first step is to initialize Terraform. This step ensures that Terraform has all the prerequisites to build your template in Azure. The next step is to have Terraform review and validate the template. This step compares the requested resources to the state information saved by Terraform and then outputs the planned execution.

The Azure resources aren't created at this point. If everything looks correct and you're ready to build the infrastructure in Azure, apply the template in Terraform:.

It omits many implementation details in order to get developers going with coding an example Provider and executing it with Terraform. Please refer to the rest of the Extending Terraform for a more complete reference on authoring Providers and Resources.

An internal private cloud whose functionality is either proprietary or would not benefit the open source community. Terraform supports a plugin model, and all providers are actually plugins.

Plugins are distributed as Go binaries. Although technically possible to write a plugin in another language, almost all Terraform plugins are written in Go. For more information on installing and configuring Go, please visit the Golang installation guide.

As a reminder, all of Terraform's core providers are open source. When stuck or looking for examples, please feel free to reference the open source providers for help. To start, create a file named provider.

This is the root of the provider and should include the following boilerplate code:. It abstracts many of the complexities and ensures consistency between providers. The example above defines an empty provider there are no resources. Go requires a main. Since Terraform plugins are distributed as Go binaries, it is important to define this entry-point with the following code:.

This establishes the main function to produce a valid, executable Go binary. The contents of the main function consume Terraform's plugin library. This library deals with all the communication between Terraform core and the plugin. The output name -o is very important. Terraform searches for plugins in the format of:. Custom built providers can be sideloaded for Terraform to use. This is the basic project structure and scaffolding for a Terraform plugin. To recap, the file structure is:.

Terraform providers manage resources.
