Deploying service invocation to Azure Kubernetes Service

Table of contents

• Step 1: Deploy service invocation to AKS
• Step 2. Test the applications running in AKS

In this assignment, you will deploy the service communication to Azure Kubernetes Service (AKS). You will use the service invocation building block provided by Dapr.

Pre-requisites

• The first part Invoke Vehicle Registration Service from Fine Collection Service using Dapr is a pre-requisite for this assignment.
• Assignment 5 - Deploying to Azure Kubernetes Service is also a pre-requisite for this assignment.

Step 1: Deploy service invocation to AKS

1. Open deploy/vehicleregistrationservice.yaml in your code editor and uncomment the following lines:

        # annotations:
            # dapr.io/enabled: "true"
            # dapr.io/app-id: "vehicleregistrationservice"
            # dapr.io/app-port: "6002"
   

   to give Vehicle Registration Service an id and a port known to Dapr.

2. Delete the image from local docker and from the Azure Container Registry:

    docker rmi fine-collection-service:1.0-SNAPSHOT
    az acr repository delete -n $CONTAINER_REGISTRY --image fine-collection-service:latest
   

   Where $CONTAINER_REGISTRY is the name of your Azure Container Registry.

3. In the root folder of FineCollectionService, run the following command to build and push the image:

    mvn spring-boot:build-image
    docker tag fine-collection-service:1.0-SNAPSHOT $CONTAINER_REGISTRY.azurecr.io/fine-collection-service:latest
    docker push $CONTAINER_REGISTRY.azurecr.io/fine-collection-service:latest
   

   Where $CONTAINER_REGISTRY is the name of your Azure Container Registry.

4. From the root folder of the repo, run the following command:

    kubectl apply -k deploy
   

Step 2. Test the applications running in AKS

1. Run the following command to identify the name of each microservice pod:

    kubectl get pods
   

2. l\Look at the log file of each application pod to see the same output as seen when running on your laptop. For example:

    kubectl logs finecollectionservice-ccf8c9cf5-vr8hr -c fine-collection-service
   

3. Delete all application deployments:

    kubectl delete -k deploy
