Things You Didn't Know About Terraform CLI

Terraform CLI is a command-line tool that allows users to build, change, and version infrastructure safely and efficiently. It is an open-source tool that is widely used by developers and system administrators to manage infrastructure as code.

Here are some things you should know about Terraform CLI:

1. Infrastructure as Code: Terraform CLI allows you to define your infrastructure as code, which makes it easy to manage and version infrastructure changes. You can define your infrastructure using a simple, human-readable configuration language called HashiCorp Configuration Language (HCL).

2. Providers: Terraform CLI supports a wide range of providers, including AWS, Azure, Google Cloud Platform, and many others. Providers allow you to interact with different cloud services and resources.

3. Modules: Terraform CLI supports modular design, which allows you to break down your infrastructure into smaller, reusable components. Modules can be shared and used across different projects, which makes it easy to maintain consistency across your infrastructure.

4. State Management: Terraform CLI uses a state file to keep track of the current infrastructure state. This state file is used to determine what changes need to be made when you run Terraform again. The state file can be stored locally or remotely, depending on your preference.

5. Plan and Apply: Terraform CLI allows you to plan your infrastructure changes before applying them. This allows you to review the changes and make sure they are what you intended. Once you are satisfied with the changes, you can apply them.

6. Versioning: Terraform CLI allows you to version your infrastructure changes using Git or any other version control system. This makes it easy to track changes over time and revert to previous versions if necessary.

In conclusion, Terraform CLI is a powerful tool for managing infrastructure as code. It allows you to define, manage, and version your infrastructure changes safely and efficiently. If you are a developer or system administrator, Terraform CLI is definitely worth checking out.
