The repository consists of the following projects and folders: 4 | 5 | * **Frontend** - A front-end web app written using ASP.NET Core Blazor Server. This web app opens a connection to a gRPC service that streams data to it continuously. 6 | * **Monitoring** - A shared project that makes it simple to configure a .NET project with Application Insights monitoring. 7 | * **SensorService** - A .NET gRPC service that has two features - it receives data from the workers via individual gRPC request/response communication, but also streams data to the frontend Blazor app. 8 | * **SensorWorker** - A .NET Worker Service project that continuously sends data to the `sensorservicegRPC` service inside the cluster. Think of each instance of the `SensorWorker` project as a physical device twin, like a thermometer. 9 | * You'll also see a series of Azure Bicep templates and a GitHub Actions workflow file in the **Azure** and **.github** folders, respectively. 10 | 11 | ## What you'll learn 12 | 13 | This exercise will introduce you to a variety of concepts, with links to supporting documentation throughout the tutorial. 14 | 15 | * [Azure Container Apps](https://docs.microsoft.com/azure/container-apps/overview) 16 | * [GitHub Actions](https://github.com/features/actions) 17 | * [Azure Container Registry](https://docs.microsoft.com/azure/container-registry/) 18 | * [Azure Bicep](https://docs.microsoft.com/azure/azure-resource-manager/bicep/overview?tabs=**bicep**) 19 | * [gRPC](https://grpc.io/) and building [gRPC apps using ASP.NET Core](https://docs.microsoft.com/aspnet/core/grpc/?view=aspnetcore-6.0) 20 | 21 | ## Prerequisites 22 | 23 | You'll need an Azure subscription and a very small set of tools and skills to get started: 24 | 25 | 1. An Azure subscription. Sign up [for free](https://azure.microsoft.com/free/). 26 | 2. A GitHub account, with access to GitHub Actions. 27 | 3. Either the [Azure CLI](https://docs.microsoft.com/cli/azure/install-azure-cli) installed locally, or, access to [GitHub Codespaces](https://github.com/features/codespaces), which would enable you to do develop in your browser. 28 | 29 | ## Topology diagram 30 | 31 | This app is represented by 1 (or more) background worker apps that make repetitive requests via gRPC to a gRPC host container. That host container aggregates the data into a stream after storing it temporarily in Memory Cache. A final container, hosting a frontend Blazor Server application, has a streaming connection to the gRPC service. 32 | 33 | ![Sample topology once deployed.](docs/media/toplogy.png) 34 | 35 | 36 | 37 | As the gRPC service receives data payloads from the individual worker instances, it streams that data constantly to the frontend web app, which displays a graph showing the data being received over time. The app demonstrates how a series of backend services can communicate internally within the Azure Container Apps environment using HTTP2 and gRPC. 38 | 39 | ## Setup 40 | 41 | By the end of this section you'll have a 3-node app running in Azure. This setup process consists of two steps, and should take you around 15 minutes. 42 | 43 | 1. Use the Azure CLI to create an Azure Service Principal, then store that principal's JSON output to a GitHub secret so the GitHub Actions CI/CD process can log into your Azure subscription and deploy the code. 44 | 2. Edit the ` deploy.yml` workflow file and push the changes into a new `deploy` branch, triggering GitHub Actions to build the .NET projects into containers and push those containers into a new Azure Container Apps Environment. 45 | 46 | ## Authenticate to Azure and configure the repository with a secret 47 | 48 | 1. Fork this repository to your own GitHub organization. 49 | 2. Create an Azure Service Principal using the Azure CLI. 50 | 51 | ```bash 52 | $subscriptionId=$(az account show --query id --output tsv) 53 | az ad sp create-for-rbac --sdk-auth --name gRPCAcaSample --role contributor --scopes /subscriptions/$subscriptionId 54 | ``` 55 | 56 | 3. Copy the JSON written to the screen to your clipboard. 57 | 58 | ```json 59 | { 60 | "clientId": "", 61 | "clientSecret": "", 62 | "subscriptionId": "", 63 | "tenantId": "", 64 | "activeDirectoryEndpointUrl": "https://login.microsoftonline.com/", 65 | "resourceManagerEndpointUrl": "https://brazilus.management.azure.com", 66 | "activeDirectoryGraphResourceId": "https://graph.windows.net/", 67 | "sqlManagementEndpointUrl": "https://management.core.windows.net:8443/", 68 | "galleryEndpointUrl": "https://gallery.azure.com", 69 | "managementEndpointUrl": "https://management.core.windows.net" 70 | } 71 | ``` 72 | 73 | 4. Create a new GitHub secret in your fork of this repository named `AzureSPN`. Paste the JSON returned from the Azure CLI into this new secret. Once you've done this you'll see the secret in your fork of the repository. 74 | 75 | ![The AzureSPN secret in GitHub](docs/media/secrets.png) 76 | 77 | > Note: Never save the JSON to disk, for it will enable anyone who obtains this JSON code to create or edit resources in your Azure subscription. 78 | 79 | ## Deploy the code using GitHub Actions 80 | 81 | The easiest way to deploy the code is to make a commit directly to the `deploy` branch. Do this by navigating to the `deploy.yml` file in your browser and clicking the `Edit` button. 82 | 83 | ![Edit the deployment file](docs/media/edit-the-deploy-file.png) 84 | 85 | Provide a custom resource group name for the app, and then commit the change to a new branch named `deploy`. 86 | 87 | ![Create the deployment branch.](docs/media/create-the-deployment-branch.png) 88 | 89 | Once you click the `Propose changes` button, you'll be in "create a pull request" mode. Don't worry about creating the pull request yet, just click on the `Actions` tab, and you'll see that the deployment CI/CD process has already started. 90 | 91 | ![Deployment started.](docs/media/deployment-started.png) 92 | 93 | When you click into the workflow, you'll see that there are 3 phases the CI/CD will run through: 94 | 95 | 1. provision - the Azure resources will be created that eventually house your app. 96 | 2. build - the various .NET projects are build into containers and published into the Azure Container Registry instance created during provision. 97 | 3. deploy - once `build` completes, the images are in ACR, so the Azure Container Apps are updated to host the newly-published container images. 98 | 99 | ![CI/CD phases.](docs/media/deployment-phases.png) 100 | 101 | After a few minutes, all three steps in the workflow will be completed, and each box in the workflow diagram will reflect success. If anything fails, you can click into the individual process step to see the detailed log output. 102 | 103 | > Note: if you do see any failures or issues, please submit an Issue so we can update the sample. Likewise, if you have ideas that could make it better, feel free to submit a pull request. 104 | 105 | ![Deployment succeeded](docs/media/deployment-success.png) 106 | 107 | With the projects deployed to Azure, you can now test the app to make sure it works. 108 | 109 | ## Try the app in Azure 110 | 111 | The `deploy` CI/CD process creates a series of resources in your Azure subscription. These are used primarily for hosting the project code, but there's also a few additional resources that aid with monitoring and observing how the app is running in the deployed environment. 112 | | Resource | Resource Type | Purpose | 113 | | ---------------- | ------------------------- | ------------------------------------------------------------ | 114 | | `prefix`grpcai | Application Insights | This provides telemetry about the application's execution, and stores traces, logs, and exception data captured by the Application Insights SDK. | 115 | | frontend | Container App | Hosts the container with the code for the frontend Blazor server application that receives streaming data from the gRPC service. | 116 | | service | Container App | Hosts the container with the code for the gRPC service that both receives requests from the individual Worker services and provides streaming data about the status of the individual workers. | 117 | | worker | Container App | Hosts the container(s) with the code for the Worker Service that sends messages representing sensor data pings (like temperature sensors or light sensors). | 118 | | `prefix`grpcenv | Container App Environment | The Azure Container App Environment, in which all of the container apps running can communicate with one another relatively openly. | 119 | | `prefix`grpcacr | Azure Container Registry | The container registry into which all of my application's microservices are published and stored prior to their being deployed as Azure Container Apps. | 120 | | `prefix`grpclogs | Log Analytics | A Log Analytics account, which provides container logs for all of the container app running in my container app environment. This is where you'll look for most `ILogger` log output using [Kusto](https://docs.microsoft.com/azure/data-explorer/kusto/query/). | 121 | 122 | The resources are shown here in the Azure portal: 123 | 124 | ![The app deployed to Azure.](docs/media/deployed-to-azure.png) 125 | 126 | Click on the `frontend` container app to open it up in the Azure portal. In the `Overview` tab you'll see a URL. 127 | 128 | ![Front end.](docs/media/front-end.png) 129 | 130 | Clicking that URL will open the app's frontend up in the browser. When it opens, you'll see a line chart that fluctuates as it receives data from the streaming gRPC API. 131 | 132 | ![App frontend.](docs/media/app-front-end.png) 133 | 134 | ## Scale the Worker 135 | 136 | Now, you can scale out the `worker` container app to simulate multiple clients feeding into the gRPC service. To do this, go into the Revision management tool in the Azure portal, and you'll see the revision(s) currently active. You may see 2 revisions even though only one of the revisions is running your code, since the original deployment housed the Azure Container Apps welcome image, and the *second* deployment (the one performed during the `deploy` CI/CD step, since `provision` creates the Azure Container App with the default welcome image). 137 | 138 | ![Revision management tab.](docs/media/revision-management.png) 139 | 140 | Click the Create new revision button, and set the Scale slider to be anything more than 1. 141 | 142 | ![Creating a new Azure Container Apps revision with +1 scale.](docs/media/new-revision.png) 143 | 144 | Once the new revision is provisioned, you should see additional charts appear in the `frontend` web app. Each time a new `worker` starts up, it represents 1 device twin feeding data to the centralized gRPC `service` container app. 145 | 146 | ![New sensor workers coming online.](docs/media/new-sensor-workers.png) 147 | 148 | ## Monitoring 149 | 150 | The application is instrumented with Azure Application Insights, and the Azure Container Apps environment has a Log Analytics dependency, so you can easily deep-dive into the logs from the application. 151 | 152 | ![Application logs in Log Analytics.](docs/media/logs.png) 153 | 154 | You can also use the Application Insights Application Map to see a high-level overview of all the nodes and containers in the application, and to see how messages are being transmitted between each container through the Azure Container Apps environment. 155 | 156 | ![Application Map for the workers and gRPC service.](docs/media/appmap.png) 157 | 158 | ## Summary 159 | 160 | This sample walks you through the creation of a distributed cloud-native app running in Azure Container Apps, which makes use of gRPC in both request/response and streaming APIs. You've also seen how to monitor and view the application's logs. Take some time and explore Azure Container Apps and what you can do with it as a solid host for your cloud-native .NET apps. 161 | -------------------------------------------------------------------------------- /SensorApp.sln: -------------------------------------------------------------------------------- 1 |  2 | Microsoft Visual Studio Solution File, Format Version 12.00 3 | # Visual Studio Version 17 4 | VisualStudioVersion = 17.2.32324.85 5 | MinimumVisualStudioVersion = 10.0.40219.1 6 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "Frontend", "Frontend\Frontend.csproj", "{472EA4A9-0AD2-44BC-A3E8-CFA380EB4D2D}" 7 | EndProject 8 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SensorService", "SensorService\SensorService.csproj", "{1A8526A6-FAD7-46A8-92C9-FD0A8BA31DEF}" 9 | EndProject 10 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SensorWorker", "SensorWorker\SensorWorker.csproj", "{42906AF7-6522-40A4-9B14-AD470DE22BBD}" 11 | EndProject 12 | Project("{9A19103F-16F7-4668-BE54-9A1E7A4F7556}") = "Monitoring", "Monitoring\Monitoring.csproj", "{BBA38D1D-E411-426F-8F59-A71E65F921AD}" 13 | EndProject 14 | Global 15 | GlobalSection(SolutionConfigurationPlatforms) = preSolution 16 | Debug|Any CPU = Debug|Any CPU 17 | Release|Any CPU = Release|Any CPU 18 | EndGlobalSection 19 | GlobalSection(ProjectConfigurationPlatforms) = postSolution 20 | {472EA4A9-0AD2-44BC-A3E8-CFA380EB4D2D}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 21 | {472EA4A9-0AD2-44BC-A3E8-CFA380EB4D2D}.Debug|Any CPU.Build.0 = Debug|Any CPU 22 | {472EA4A9-0AD2-44BC-A3E8-CFA380EB4D2D}.Release|Any CPU.ActiveCfg = Release|Any CPU 23 | {472EA4A9-0AD2-44BC-A3E8-CFA380EB4D2D}.Release|Any CPU.Build.0 = Release|Any CPU 24 | {1A8526A6-FAD7-46A8-92C9-FD0A8BA31DEF}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 25 | {1A8526A6-FAD7-46A8-92C9-FD0A8BA31DEF}.Debug|Any CPU.Build.0 = Debug|Any CPU 26 | {1A8526A6-FAD7-46A8-92C9-FD0A8BA31DEF}.Release|Any CPU.ActiveCfg = Release|Any CPU 27 | {1A8526A6-FAD7-46A8-92C9-FD0A8BA31DEF}.Release|Any CPU.Build.0 = Release|Any CPU 28 | {42906AF7-6522-40A4-9B14-AD470DE22BBD}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 29 | {42906AF7-6522-40A4-9B14-AD470DE22BBD}.Debug|Any CPU.Build.0 = Debug|Any CPU 30 | {42906AF7-6522-40A4-9B14-AD470DE22BBD}.Release|Any CPU.ActiveCfg = Release|Any CPU 31 | {42906AF7-6522-40A4-9B14-AD470DE22BBD}.Release|Any CPU.Build.0 = Release|Any CPU 32 | {BBA38D1D-E411-426F-8F59-A71E65F921AD}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 33 | {BBA38D1D-E411-426F-8F59-A71E65F921AD}.Debug|Any CPU.Build.0 = Debug|Any CPU 34 | {BBA38D1D-E411-426F-8F59-A71E65F921AD}.Release|Any CPU.ActiveCfg = Release|Any CPU 35 | {BBA38D1D-E411-426F-8F59-A71E65F921AD}.Release|Any CPU.Build.0 = Release|Any CPU 36 | EndGlobalSection 37 | GlobalSection(SolutionProperties) = preSolution 38 | HideSolutionNode = FALSE 39 | EndGlobalSection 40 | GlobalSection(ExtensibilityGlobals) = postSolution 41 | SolutionGuid = {F89CC252-4DCF-4E7A-AEA9-F225B2F6A485} 42 | EndGlobalSection 43 | EndGlobal 44 | -------------------------------------------------------------------------------- /SensorService/Dockerfile: -------------------------------------------------------------------------------- 1 | #See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging. 2 | 3 | FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base 4 | WORKDIR /app 5 | EXPOSE 80 6 | EXPOSE 443 7 | 8 | FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build 9 | WORKDIR /src 10 | COPY ["SensorService/SensorService.csproj", "SensorService/"] 11 | COPY ["Monitoring/Monitoring.csproj", "Monitoring/"] 12 | RUN dotnet restore "SensorService/SensorService.csproj" 13 | COPY . . 14 | WORKDIR "/src/SensorService" 15 | RUN dotnet build "SensorService.csproj" -c Release -o /app/build 16 | 17 | FROM build AS publish 18 | RUN dotnet publish "SensorService.csproj" -c Release -o /app/publish 19 | 20 | FROM base AS final 21 | WORKDIR /app 22 | COPY --from=publish /app/publish . 23 | ENTRYPOINT ["dotnet", "SensorService.dll"] -------------------------------------------------------------------------------- /SensorService/Program.cs: -------------------------------------------------------------------------------- 1 | using SensorService.Services; 2 | 3 | var builder = WebApplication.CreateBuilder(args); 4 | 5 | // Add services to the container. 6 | builder.Services.AddGrpc(); 7 | builder.Services.AddMemoryCache(); 8 | builder.Services.AddWebApplicationMonitoring(); 9 | 10 | var app = builder.Build(); 11 | 12 | // Configure the HTTP request pipeline. 13 | app.MapGrpcService(); 14 | app.MapGet("/", () => "Communication with gRPC endpoints must be made through a gRPC client.
