Overview
VOL app infrastructure is deployed using Terraform. The Terraform code is located in the /infra/terraform directory.
The Terraform code is split into multiple modules, located
in /modules directory. Each module will contain an
auto-generated README.md file which will provide more information about the module.
README.md files are automatically generated by terraform-docs.
The relationship between the Terraform directory structure is as per the diagram below:
