ASP.NET Core Front-end + 2 Back-end APIs on Azure Container Apps

This repository contains a simple scenario built to demonstrate how ASP.NET Core 6.0 can be used to build a cloud-native application hosted in Azure Container Apps. The repository consists of the following projects and folders:

• Catalog API - this is an ASP.NET minimal API project with one endpoint.
• Orders API - this is an ASP.NET minimal API project with one endpoint.
• UI - an ASP.NET Blazor Server app that calls out to both the Catalog and Orders API and renders their status.
• deploy folder - this folder contains a series of Azure Bicep templates that can be used to create the application and deploy it.
• setup.ps1 - this file is a one-stop way for you to deploy the app to your own Azure subscription so you can try the scenario.

Prerequisites

• .NET 6.0
• The Azure CLI
• An Azure subscription
• Docker
• PowerShell (GitHub Actions will replace this prerequisite soon)

Setup

1. Clone this repository.
2. Sign in to your Azure subscription using the az login command.
3. If you have more than 1 Azure subscription, make sure you're targeting the right Azure subscription by using the az account show and az account set -s <subscription-id> commands.
4. From the root of this repository, run ./setup.ps1.

Topology diagram

The resultant application is an Azure Container Environment-hosted set of containers - the catalog API, the orders API, and the frontend Razor Pages front-end.

Internet traffic should not be able to directly access either of the back-end APIs as each of these containers is marked as "internal ingress only" during the deployment phase. Internet traffic hitting the frontend.<your app>.<your region>.azurecontainerapps.io URL should be proxied to the frontend container, which in turn makes outbound calls to both the catalog and orders APIs within the Azure Container Apps Environment.
