It is a declarative language that allows you to describe your infrastructure in a simple and easy-to-understand way.

In this article, we will discuss the top 10 Terraform commands that every developer should know. These commands will help you get started with Terraform and automate your infrastructure deployment process.

1. terraform init

The first command that you need to know is terraform init. This command initializes a new or existing Terraform working directory.

This command is useful for verifying that your infrastructure changes are correct before you apply them.

3. terraform apply

The third command that you need to know is terraform apply. This command applies the changes to your infrastructure. It creates, modifies, or deletes the resources as per your configuration. This command is useful for automating your infrastructure deployment process.

4. terraform destroy

The fourth command that you need to know is terraform destroy. This command destroys the resources created by Terraform. It is useful for cleaning up your infrastructure after you are done with it. This command should be used with caution as it can delete your resources permanently.

5. terraform validate

The fifth command that you need to know is terraform validate. This command validates the syntax and configuration of your Terraform files. It checks for errors and warnings in your configuration files. This command is useful for catching errors before you apply the changes to your infrastructure.

6. terraform state

The sixth command that you need to know is terraform state. This command shows you the current state of your infrastructure. It is useful for debugging and troubleshooting your infrastructure. You can use this command to view the attributes of your resources and their dependencies.

7. terraform output
