Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.
- Why care about Terraform project structure? Simple—it keeps things organized so you can scale up, work well with your team, and keep everything secure. No fuss, just a setup that works.
This setup follows a layered structure, separating resources by environment (development, staging, production, etc.) and using centralized modules for reusable components.
Modules are kept in a central repository, allowing environments to source specific versions for controlled updates and consistent configurations.
Defines core resources for the environment by referencing modules from the central repository. Each module is tagged to ensure a specific version is used.
Example:
Declares input variables, making the configuration adaptable. For example, instance_type might vary between environments (e.g., t2.micro in dev, t3.large in prod).
Example:
Configures the cloud provider and backend for remote state storage, which tracks deployed resources. This setup is crucial for collaborative workflows.
Example:
Defines output values, making it easy to retrieve information, like IP addresses or resource IDs, after deployment.
Example:
Contains values for variables declared in variables. tf, tailored to this environment. Each environment (dev, staging, prod) will have its own .tfvars file.
Example:
Modules are organized into folders by type (e.g., network, compute) within a separate repository. This structure allows consistent usage across environments by sourcing each module from a specific version tag in the central repository.

If you're new to Terraform and want to get started creating infrastructure, please check out our Getting Started guides on HashiCorp's learning platform. There are also additional guides to continue your learning.
Show off your Terraform knowledge by passing a certification exam. Visit the certification page for information about exams and find study materials on HashiCorp's learning platform.
-
Use versioned module tags.
-
Centralize module source in a remote repository.
-
Refactor modules for reusability as the project scales.
-
Avoid hardcoding values; use variables for flexibility.
-
Keep module logic focused on a single responsibility.
-
Define clear input and output variables for each module.
-
Document module usage and parameters in a README.
-
Test modules independently before applying them in environments.
