kubectl apply -f 01-namespaces.yaml

After applying the manifest, the new namespaces should show up when you run kubectl get namespaces. The following screenshot shows a list of the Kubernetes cluster namespaces:

The following steps entail the deployment of our database services, followed by the deployment of the monolithic Links 'R' Us application.
