Scale the Backend Services

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

When we launched our services, we only launched one container of each. We can confirm this by viewing the running pods:

kubectl get deployments

Now let’s scale up the backend services:

kubectl scale deployment ecsdemo-nodejs --replicas=3
kubectl scale deployment ecsdemo-crystal --replicas=3

Confirm by looking at deployments again:

kubectl get deployments

Also, check the browser tab where we can see our application running. You should now see traffic flowing to multiple backend services.
