We are excited to announce the launch of tofu-template-tester on May 20, 2025. This new lightweight CLI tool, written in Go, is designed to simplify the way developers and operators handle dynamic configuration files by providing a streamlined method for rendering Terraform-compatible templates.

Key Capabilities

tofu-template-tester provides a robust set of features to ensure your template rendering is both flexible and efficient:

  • Seamless Template Rendering: Easily replace ${VARIABLE} placeholders in your input files or via STDIN with precise values.
  • Flexible I/O Options: Whether you prefer working with files via -in and -out or piping data through STDOUT and STDIN, the tool adapts to your workflow.
  • Automated Variable Discovery: No more guessing which variables are required. The -list-params flag scans your templates and lists every unique variable that needs a value.
  • Dynamic Input Methods: Choose between loading assignments from a properties file using -properties for automated environments, or using the -interactive mode to be prompted for missing values directly in your terminal.

Why It Matters

Managing configuration files often involves a trade-off between static simplicity and dynamic complexity. tofu-template-tester bridges this gap by allowing you to maintain Terraform/OpenTofu compatible templates while injecting values at runtime. This approach reduces the risk of manual editing errors and enables a more programmatic approach to infrastructure configuration without requiring heavyweight tooling.

Getting Started

You can get started with tofu-template-tester today. If you have Go installed, you can install it directly from source:
