Challenge 8 - Dapr-enabled Services running in Azure Kubernetes Service (AKS)

< Previous Challenge - Home

Introduction

In this challenge, you're going to deploy the Dapr-enabled services you have written locally to an Azure Kubernetes Service (AKS) cluster.

architecture

  • Update all the port numbers to use the Dapr defaults since it will be running in AKS.
  • Create a Kubernetes secret in your AKS cluster that references your Azure KeyVault secrets.
  • Update the Dapr secret configuration file to pull secrets from the Kubernetes secret.
  • Build Docker images of all 3 services & upload to the Azure Container Registry.
  • Deploy your service images to your AKS cluster.
  • Run your Simulation service locally.

Success Criteria

To complete this challenge, you must reach the following goals:

  • Validate that all 3 services are compiled into Docker images & stored in an Azure Container Registry.
  • Validate that you have successfully deployed all 3 services (VehicleRegistrationService, TrafficControlService & FineCollectionService) to an AKS cluster.
  • Validate that the local Simulation service runs & connects to your AKS-hosted services and that all the previous functionality still works (input messages, output messages, speeding violation emails, etc).

Tips

  • Use ACR Tasks to simplify creation & deployment of the images to the registry.
  • Modify the Resources/dapr/components/fine-collection-service.yaml (and other services) spec files to deploy each service to AKS. You will need to customize them with the names of your specific Azure container registries, etc.
  • Use the Kubernetes Kustomize command to deploy all the services in the Resources/dapr/components directory simulatiously 
    cd Resources/dapr/components
kubectl apply -k .

Learning Resources

Thanks for participating in these hands-on challenges! Hopefully you've learned about Dapr and how to use it. Obviously, these challenges barely scratch the surface of what is possible with Dapr. We have not touched upon subjects like: hardening production environments, actors, integration with Azure Functions, Azure API Management and Azure Logic Apps just to name a few. So if you're interested in learning more, I suggest you read the Dapr documentation.
