Cleanup the applications

To delete the resources created by the applications, we should delete the application deployments:

Undeploy the applications:

cd ~/environment/ecsdemo-frontend
kubectl delete -f kubernetes/service.yaml
kubectl delete -f kubernetes/deployment.yaml

cd ~/environment/ecsdemo-crystal
kubectl delete -f kubernetes/service.yaml
kubectl delete -f kubernetes/deployment.yaml

cd ~/environment/ecsdemo-nodejs
kubectl delete -f kubernetes/service.yaml
kubectl delete -f kubernetes/deployment.yaml
