Terraform Module Telemetry Collection Service

This repository contains the Terraform Module Telemetry Collection Service. This project is divided into four parts, all written in Terraform.

Overview

• resource_group: Creates an Azure resource group.
• acr: Creates an Azure Container Registry along with virtual network and subnets and corresponding private endpoints. This ACR registry is only accessible via the VNet.
• docker_image: Contains a sub-folder named telemetry which contains a main.go file. This Go application uses Iris as a web server to collect tags sent from a Terraform provider named modtm, enabling us to collect usage telemetry data from our Terraform module users. This part will compile the HTTP server application into a Docker image and push it into the ACR created previously.
• container_apps: Uses the Azure Container Apps Module to create an Azure Container Apps instance to host the web application pushed into the ACR.

Due to an issue with the Docker provider (#483), we can't use the ACR resource's login_url and password outputs directly in the Terraform Docker provider's config. Therefore, when we provision this stack from scratch, we need use -target to provision the base modules first:

$ terraform apply -target="module.resource_group" -target="module.acr"

Prerequisites

• Azure credentials configured as per the AzureRM Provider documentation.

Provisioning

To provision the whole solution, execute the following command in the repository's root folder:

terragrunt run-all apply --terragrunt-non-interactive

This command will use your Azure credentials to provision the resources defined in the Terraform modules.
