exercise 2

Terraform is an infrastructure-as-code (IaC) platform that allows users to manage and integrate various external resources as united infrastructure. This is achieved by using the proprietary HashiCorp Configuration Language (HCL) or JSON.

This course is a comprehensive introduction to Terraform. It helps users build confidence through foundational understanding of Terraform’s approach to resource management and the coding environment. You’ll start with an introduction to Terraform and learn how to set up local files. You’ll then take your learning to the cloud, managing remote resources by identifying unique resources and dependencies. Next, you’ll learn the modules and data structures unique to Terraform before practicing various techniques for infrastructure management, including triggers, resource creation, and backend code.

By the end of this course, you’ll have learned to think creatively and be ready to solve production and deployment problems through Terraform.

Beginner’s Guide to Terraform

# Modules

We’ve already made and used Terraform modules, but in this lesson, we’ll reference a module and combine it with another one.



Like libraries, we can reference them in other Terraform modules without necessarily being concerned with the other module’s implementation details.


Like functions, modules can have inputs and outputs. However, we don’t need to be concerned with their implementation details for this course.


We’ll create a module and then use it from another module to work through the basic library functionality. Understanding how Terraform modules work is vital in regular Terraform usage.



# Create a module
 
We’ve created a directory in order to understand how to reference a module and named it  `ltthw_modules`. Then we created `hello_module` and `hello_module_consumer_1` directories with `hello_module.tf` and `hello_module_consumer_1.tf` files, respectively.



You may have noticed that we created an extra directory level. Instead of just creating a folder structure like  ltthw_modules/hello_module.tf, we created ltthw_modules/hello_module/hello_module.tf.


We know we can create multiple modules in multiple subfolders within  `ltthw_modules`. We’ve created the `hello_module` module, then we created a module that consumes the `hello_module` as a library module. The second module `hello_module_consumer_1` will source the `hello_module`.

# Reference a module


In this module we’ll learn how to reference a module. We’ve created another module called `hello_module_consumer_1` that sources the `hello_module` and creates the local file specified in that module. Next, we are going to run this module up. Think about what you expect will happen when we run it.
