Test the Application

This workshop has been deprecated and archived. The new Amazon EKS Workshop is now available at www.eksworkshop.com.

Testing the Connectivity between Fargate and Nodegroup pods

To test if our ported Product Catalog App is working as expected, we’ll first exec into the frontend-node container.

export FE_POD_NAME=$(kubectl get pods -n prodcatalog-ns -l app=frontend-node -o jsonpath='{.items[].metadata.name}') 

kubectl -n prodcatalog-ns exec -it ${FE_POD_NAME} -c frontend-node bash

You will see a prompt from within the frontend-node container.


root@frontend-node-9d46cb55-XXX:/usr/src/app#

curl to Fargate prodcatalog backend endpoint and you should see the below response

curl http://prodcatalog.prodcatalog-ns.svc.cluster.local:5000/products/ 


{
    "products": {},
    "details": {
        "version": "1",
        "vendors": [
            "ABC.com"
        ]
    }
}

Exit from the frontend-node container exec bash. Now, To test the connectivity from Fargate service prodcatalog to Nodegroup service proddetail, we’ll first exec into the prodcatalog container.

export BE_POD_NAME=$(kubectl get pods -n prodcatalog-ns -l app=prodcatalog -o jsonpath='{.items[].metadata.name}') 

kubectl -n prodcatalog-ns exec -it ${BE_POD_NAME} -c prodcatalog bash

You will see a prompt from within the prodcatalog container.


root@prodcatalog-98f7c5f87-xxxxx:/usr/src/app#
curl to Nodegroup proddetail backend endpoint and you should see the below response. You can now exit from prodcatalog exec bash.

curl http://proddetail.prodcatalog-ns.svc.cluster.local:3000/catalogDetail


{"version":"1","vendors":["ABC.com"]}

Congratulations on deploying the initial Product Catalog Application architecture!

Before we create the App Mesh-enabled versions of Product Catalog App, we’ll first install the AWS App Mesh Controller for Kubernetes into our cluster.
