What is terraform?

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. It can be used to manage infrastructure for a variety of cloud providers, including AWS, Azure, Google Cloud, and more.

Here is a brief tutorial on how to get started with Terraform:

1. Download and install Terraform on your local machine by following the instructions on the Terraform website.
2. Create a new directory for your Terraform project and open a terminal in that directory.
3. Initialize Terraform in your project directory by running the terraform init command. This will download any necessary plugins for the cloud providers you want to use.
4. Create a file named main.tf in your project directory. This file will contain the configuration for your infrastructure.
5. Write your infrastructure configuration in the main.tf file using the HashiCorp Configuration Language (HCL). This configuration will define the resources you want to create, such as virtual machines, network interfaces, and more.
6. Preview the changes that will be made to your infrastructure by running the terraform plan command. This will show you a summary of the actions that will be performed.
7. Apply the changes to your infrastructure by running the terraform apply command. This will create the resources defined in your configuration.
8. To make changes to your infrastructure, modify the configuration in your main.tf file and then run the terraform apply command again. Terraform will detect the changes and update your infrastructure accordingly.

That’s the basics of getting started with Terraform! For more detailed information, including information on advanced features and best practices, please see the Terraform documentation.
