Managing cloud resources effectively can feel like an uphill battle, especially when you’re tasked with ensuring proper tagging across multiple infrastructures. Welcome to Terratag, a CLI tool that makes this daunting task easy. With Terratag, you can apply tags to AWS, GCP, and Azure resources in your OpenTofu Terraform files. Let’s walk through how to get started with Terratag and fully utilize its capabilities!

What is Terratag?

Terratag is an innovative CLI tool designed to effortlessly apply tags and labels across an entire set of OpenTofu Terraform files. It allows for consistent tagging of cloud resources, saving you time and frustration.

Why Use Terratag?

Maintaining tags across your application can be complex and tedious. Manually adding tags for each component often leads to inconsistencies and oversight. Terratag streamlines the tagging process, enabling you to save time and significantly simplify future updates. You can read more about why tagging is important.

Getting Started: Prerequisites and Installation

Prerequisites

• OpenTofu 1.x or Terraform 0.12 through 1.x

Installation Steps

1. To install from homebrew, run:

brew install env0/terratag/terratag

2. Alternatively, download the latest release binary.

How to Use Terratag?

Running Terratag

After installation, follow these steps to tag your resources:

1. Initialize OpenTofu Terraform modules:

tofu init

terraform init

2. Run the Terratag command:

terratag -dir=foobar -tags=environment_id:prod

Or to add multiple tags:

terratag -dir=foobar -tags=environment_id=prod,some-tag=value

Understanding the Output

Think of your Terraform files as a library. Before applying Terratag, the books (resources) are scattered and unmarked. After running the command, each book is tagged accurately, allowing for efficient search and retrieval later, and even backup copies are made!

Using Optional CLI Flags

Terratag includes several optional flags to tailor its functionality:

• -dir=path: Sets the OpenTofu Terraform folder (default is ..).
• -skipTerratagFiles=false: Skip processing *.terratag.tf files on subsequent runs.
• -filter=regular expression: Only apply tags to resource types that match the expression.
• -verbose: Turn on verbose logging for better insights.

Troubleshooting Tips

While you’re setting up Terratag, challenges can arise. Here are some common issues and their solutions:

• Issue: Terratag fails to apply tags.
  
  Solution: Ensure you have correctly initialized the OpenTofu Terraform modules and that you are in the right directory.
• Issue: Output files are not created.
  
  Solution: Check if you are using the correct command syntax or if the directory path is set correctly.
