Terraform allows you to define and create complete infrastructure deployments in Azure. 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:. Once Terraform completes, your VM infrastructure is ready. Obtain the public IP address of your VM with az vm show :.
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.
Using Terraform to import existing resources on Azure Ask Question. Asked 2 years, 4 months ago. Active 1 year, 5 months ago. Viewed 10k times. 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.
Defaults to the configured backend, or "terraform. If this isn't specified, the source state file will be used. This can be a new or existing path. This flag can be set multiple times. This is only useful with the "-config" flag. If "terraform.With Terraform you can use a single language to describe your infrastructure in code. This guide explains the core concepts of Terraform and essential basics that you need to spin up your first Azure environments.
Infrastructure as Code IaC is the process of describing infrastructural components such as servers, services, or databases using a programming language. Once all infrastructural requirements are described in code, that code can be stored in source control.
Source control means that the infrastructure is versionedtransparentdocumentedtestablemutable and discoverable. Once the first version is stored in source controlall team members see which infrastructure is required to bring a project alive. Everyone sees which configuration settings are required to make -for example- the database perform as good as expected.
Changes are done to the infrastructure exist as dedicated commits -or more significant changes as pull requests - and will be reviewed by peers before being merged into the latest version. The code is also easy to test and on top, Continuous Integration CI builds can execute existing tests automatically with no human interaction. Having tests means errors in the infrastructure configuration are spotted earlier.
This is also a critical risk reduction for every project. John gave his best to describe all essential infrastructure parts and their configuration values. However, modern software projects evolve. So there is a good chance that John has some critical information only in his head… Maybe has Tim -the guy who sits next to John- some tribal knowledge about the Redis configuration, but would you bet on it?
That said, everyone on the team knows John. Everyone trusts him. However, every teammate is afraid when John wants to take a couple of weeks off and go on vacation.
Look at your current project team and try to spot John. Everybody knows situations or constellations like these. Terraform is currently the best tool to implement IaC. With Terraform you can create, modify and destroy environments safely and efficiently. HashiCorp created a small, yet powerful tool which can talk to numerous platforms using a flexible provider model.So I decided it was time for some investigation.
The rest of this article are my views from what I have experienced so far. I can really see the benefits in this, especially if you are deploying resources that span cloud providers. The example provided for this scenario, deploying a cloud server in one vendor and adding a DNS entry in a different cloud vendor, is a pretty good showing of how this could do some really cool things, if your operating in this world. The obvious one is resource groups, which are defined as first class objects in a Terraform template and resources placed in them, I prefer this approach to the ARM one where the resource group is implied through the command to run the template rather than actually part of the template.
In addition to resource groups Terraform can also create storage containers, queues, tables and file shares, which is currently not possible in an ARM template. This is an interesting one.
This state file is used to store the state of the infrastructure that it is deployed, separate to that infrastructure. Coming from an ARM template world this seems a little odd initially, as now you have to manage a separate file rather than relying on the infrastructure its self, but there are some benefits to using this approach:.
Quickstart: Create a complete Linux virtual machine infrastructure in Azure with Terraform
Terraform includes ways to be able to share state between people working in the same environment remote state and having different state between environments workspaces. It is also possible to refresh the state to make sure that it is inline with the existing deployment.
This looks at the state file and the template you are trying to deploy and determines what changes it needs to make, without actually making any, it then presents you with a summary of what the deployment will change in this environment. This is not only documenting what it is going to change, but it is also creating the deployment plan it will use to create the resources.
This provides two benefits:. Data sources are configuration objects in Terraform that allow you to collect data from outside of Terraform. There are a wide range of data source available with in each provider, for example in the Azure provider we can use data sources to pull in information about existing resources such as DNS Zones, RBAC Roles, Disk Images etc, similar providers exist for AWS resources and other cloud providers. There are also more generic data sources that allow you to pull data from a file or zip, as well as providers for services like Git, Data Dog, New Relic etc.
If none of these built in providers meet your needs there is also the external data source that allows you to call a script and read data from that, so long as it is returned as JSON. Modules in Terraform provide a way to create re-usable code. This makes code reuse within your organisation much easier.
Not everything about Terraform was an improvement on ARM templates, there where some areas of concern:. Obviously resources in Terraform are created by Hashicorp, so there is potential for a delay between Azure resources being released by Microsoft and them being available to create in Terraform. Resources seem to be added pretty quickly, for example there is already a resource for AKS, but there are some things missing.
There is a way round this, because you can have Terraform just deploy an ARM template, but this is an unpleasant solution. We mentioned above the benefits of using state files, however there are some downsides too. Firstly you have an extra file that is critical to your deployments that you need to manage and keep safe. The metadata that Terraform records in the state file is nowhere else but the state file. Obviously you can work with this by storing your state file in a central location that is backed up etc.
Additionally state is tied to your environment, so each time you want to deploy another instance of your infrastructure your going to need to manage another state file. The use of work-spaces manages this for you in some respects, allowing you to easily swap between environments, but you still need to manage and look after those file. With ARM templates I know so long as I deploy to the right resource group then everything should go where it needs.
The second issue with state is around security. If these items are sensitive this can be a real issue.HashiCorp Terraform AzureRM Provider and Modules for Azure
If you take the example we used above to create a storage account, the state file contains all the information about the storage account, including the storage keys in plain text. With ARM templates I can maintain my Parameters in a parameter file and pass it into the deployment command at deploy time.
If I want to use a different set of parameters I can just pass in a different file. One other benefit with parameter files in ARM is that you could reference an Azure Keyvault directly for your secrets.
Assuming your deployment account had access to the vault it would pull the secrets out directly and use them. Terraform has some really interesting concepts, I can see some definite benefits over ARM templates in certain areas and I actually really enjoyed working with it.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

More information on how to configure a Service Principal using Managed Service Identity can be found in this guide. For some advanced scenarios, such as where more granular permissions are necessary - the following properties can be set:. By default, Terraform will attempt to register any Resource Providers that it supports, even if they're not used in your configurations to be able to display more helpful error messages.
If you're running in an environment with restricted permissions, or wish to manage Resource Provider Registration outside of Terraform you may wish to disable this flag; however please note that the error messages returned from Azure may be confusing as a result example: API version was not found for Microsoft.
It's also possible to use multiple Provider blocks within a single Terraform configuration, for example to work with resources across multiple Subscriptions - more information can be found in the documentation for Providers. It's possible to configure the behaviour of certain resources using the features block - more details can be found below.

This article illustrates an example use of deployment slots by walking you through the deployment of two apps via GitHub and Azure.
One app is hosted in a production slot. The second app is hosted in a staging slot. The names "production" and "staging" are arbitrary. They can be whatever is appropriate for your scenario. After you configure your deployment slots, you use Terraform to swap between the two slots as needed. Azure subscription : If you don't have an Azure subscription, create a free account before you begin.
Open Azure Cloud Shell. If you didn't select an environment previously, select Bash as your environment. Provision the resources that are defined in the deploy.
Confirm the action by entering yes at the prompt. Before you can test the creation and swapping in and out of the deployment slots, you need to fork the test project from GitHub.
Browse to the awesome-terraform repo on GitHub. After Azure makes the connection and displays all the options, select Authorization.
