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.
