Deploying with Terraform

Overview

Terraform is an open-source infrastructure as code tool that lets you build, change, and version cloud and on-prem resources safely and efficiently.

The basic structure of Terraform that we will use in this guide includes:

• Blocks: These are the fundamental components of Terraform configuration, with each block representing a part of the configuration such as resource, output, module, etc. In addition to the main blocks, we also use another type called nested blocks (blocks within blocks).
• Arguments: Used to configure attributes of blocks. One special type of argument can be used across multiple resource types but operates with a common mechanism called meta-arguments like count, for_each,…
• Attributes: Used to access values of resources after they are created.

Modules: To facilitate management, we divide the lab into 3 modules, categorized into 2 types:

• Root Module: The main module containing the entire Terraform configuration.
• Child Module: Submodules used within the root module to separate different parts of the configuration. In this section, we will build 2 child modules:
  • Static web module: Creating S3 and configuring a static website.
  • Cicd module: Serving the storage and deployment process of source code.

You can refer to the Terraform source code here.

Conclusion

After completing the lab, we hope you can draw conclusions about the two deployment methods.
