Varlink

Varlink is a tool for managing Terraform variables and environments. It simplifies the process of setting up Terraform environment variables based on .tfvars files in your project structure.

Features

• Automatically finds and parses .tfvars files
• Sets Terraform environment variables (TF_VAR_*)
• Supports multiple environments (dev, staging, prod, etc.)
• Allows specifying search depth for .tfvars files
• Provides a dry-run mode to preview actions
• Can deactivate all Terraform-related environment variables
