Compose infrastructure as code in a Terraform file using HCL to provision resources from any infrastructure provider. Infrastructure automation workflows terrafrom aws compose, collaborate, reuse, and provision infrastructure as code across IT operations and teams of developers. Establish guardrails for security, compliance, and cost management through role-based access controls, policy enforcement, and audit. Use infrastructure as code to automate the provisioning of your infrastructure including servers, terrafrom aws, databases, firewall policies, and almost any other resource.

Terraform is an IaC software tool that provides a consistent command line interface CLI workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files. For deployment with Terraform, use the same principles used in CDK. The code is structured in modules that allow the networking components to be customized and reused according to the vendor requirements. The configuration is all parameterized, which allows the deployments to be fully tailored according to providers and ISV recommendations. The required AWS infrastructure is created and managed via a central repository.

With Terraform installed, you are ready to create your first infrastructure. EC2 instances are virtual machines running on AWS, and a common component of many infrastructure projects. To follow this tutorial you will need:. Now, set your secret key. If you don't have access to IAM user credentials, use another authentication method described in the AWS provider documentation. This tutorial will provision resources that qualify under the AWS free tier. If your account does not qualify for free tier resources, we are not responsible for any charges that you may incur. The set of files used to describe infrastructure in Terraform is known as a Terraform configuration. Each Terraform configuration must be in its own working directory. Create a directory for your configuration. Change into the directory.

Modules, like other Terraform resources, understand your order of dependencies.

In this article, we will give an overview of what providers are in Terraform, and show how to use the provider for Amazon Web Services AWS with some useful examples. A provider in Terraform is a plugin that enables interaction with an API. This includes Cloud providers such as AWS. The providers are specified in the Terraform configuration code, telling Terraform which services it needs to interact with. For more details on Terraform providers including the Spacelift Terraform provider , check out our previous article: Terraform Providers Overview. OpenTofu retained all the features and functionalities that had made Terraform popular among developers while also introducing improvements and enhancements.

Programmable infrastructures allow you to manage on-premises and cloud resources through code instead of with the management platforms and manual methods traditionally used by IT teams. An infrastructure captured in code is simpler to manage, can be replicated or altered with greater accuracy, and benefits from all sorts of automation. It can also have changes to it implemented and tracked with the version control methods customarily used in software development. Programmable infrastructures become particularly interesting when you provision workloads on a hybrid cloud environment that consists of on-premises and public cloud resources. Two services— AWS CloudFormation and Terraform by HashiCorp —allow you to express your infrastructure resources as code and manage them programmatically. Each has its advantages, but some enterprises already have expertise in Terraform and prefer using it to manage their Amazon Web Services AWS resources. In this post, we show you how to use Terraform to control your AWS resources programmatically. AWS CloudFormation codifies the details of an infrastructure into a configuration file, referred to as a template. CloudFormation currently supports a large number of resources. Terraform is not on the list of currently supported resources, so Cloudsoft had to create a registry resource for it.

Managing infrastructure across multiple environments and regions can be an operational headache for teams as applications scale. Provisioning resources manually is boring and time-consuming while scripting the process requires significant engineering effort. Infrastructure as code IaC tools like HashCorp's Terraform provides a compelling solution - allowing you to define reusable configurations for spinning up everything from storage buckets to Kubernetes clusters. I will cover the prerequisites, configuring access to AWS, writing a simple Terraform configuration, modifying your infrastructure, and then cleaning up. Whether you're already using AWS or looking to explore it with an IaC approach, this article will equip you with the fundamentals for provisioning just about any infrastructure you need. Before you can start using Terraform to manage infrastructure on AWS, you need a few prerequisites:. For this guide, you need an AWS account. Accounts are free to sign up for. As part of the account creation process, you will create a root user who has complete access to the account. For security best practices, you will be creating an IAM user with more limited permissions for Terraform to use.

To verify if we have correctly declared and referred local variables in our code, run terraform plan and observe that it does not throw any error. Run terraform apply to see the values being generated. Automate key networking tasks like updating load balancer target pools or applying firewall policies. Terraform also supports several other remote backends you can use to store and manage your state. Use the list subcommand to list of the resources in your project's state. Use HashiCorp Vault to automate the usage of dynamically generated secrets and credentials within Terraform configurations. As we can see from the output, Terraform has only destroyed one resource, i. When writing this tutorial, the latest version of Terraform was v1. When Terraform created this EC2 instance, it also gathered the resource's metadata from the AWS provider and wrote the metadata to the state file. Manage virtual images Build and manage virtual images with Terraform and Packer. The names provider , variables , and main are generic conventions used in the ecosystem. A provider is a plugin that Terraform uses to create and manage your resources.

Terraform allows you to reference output variables from one module for use in different modules. This is the magic behind using outputs from other modules as input variables. We will discuss modules in the upcoming sections. Congratulations, if you have managed to reach this point! Finally, create a variables. Any operation or a CLI command that does not involve invoking any cloud provider API are core functions of this binary. For more detail on the concepts used in this tutorial:. To do that, you will need to configure the process in a named profile, and this configuration will take place in a shared credentials file. Together, the resource type and resource name form a unique ID for the resource. The configuration is all parameterized, which allows the deployments to be fully tailored according to providers and ISV recommendations. Thus once developed, infrastructure provisioning and de-provisioning cycles execute identically. A resource might be a physical or virtual component such as an EC2 instance, or it can be a logical resource such as a Heroku application.
