Challenge 1 - Run the TrafficControl application

< Previous Challenge - Home - Next Challenge >

Introduction

In this challenge, you'll run the reference application to ensure that everything works correctly.

Description

As mentioned in the introduction, the hackathon challenges are built upon an existing microservice reference app, entitled the Traffic Control Application. To start, you'll test the Traffic Control app to ensure that the application runs and your environment is configured correctly. You'll use Visual Studio Code to start each of the 4 microservices shown below:

Keep in mind that you'll be running the application without Dapr technology. As you work through the challenges, you'll add Dapr-enable the application by adding Dapr Building Blocks and Components to it. Figure depicts the microservices in the reference application.

Run the TrafficControl application & services locally.

  • Run the Vehicle Registration microservice. It exposes a single endpoint that listens for requests for vehicle and owner information.
  • Run the Fine Collection service. It exposes an endpoint that assigns a fine to a speeding vehicles. To generate a fine, the Fine Collection service must make a call to the Vehicle Registration to obtain driver information.
  • Run the Traffic Control service. It exposes entry and exit endpoints that capture a vehicle's a speed. When a motorist exceeds the speed limit, Traffic Control will call the Fine Collection service.
  • Run the Simulation service. It simulates vehicle traffic at varying speeds. It exposes entry and exit cameras that photograph the license plate of each vehicle. Vehicle telemetry is sent to the Traffic Control service.
    • The Camera Simulation service is implemented as a Console application, the other services as API applications.

Success Criteria

  • Validate that you have successfully started each of the four microservices with no errors.
  • Observe activity flow from the top-level simulation app all the way through the FineCollectionService.

Tips

  • Run the services in VS Code using a dotnet run command.
    • Using a single VS Code instance, open a Terminal window for each service.
  • If you encounter an error, double-check to ensure that you have correctly installed all the prerequisites!
