Katacoda scenarios for the Kubernetes.io site at https://kubernetes.io/docs/tutorials/kubernetes-basics/
The ordering is a little confusing and the directories numbering does not match the modules on the Kubernetes site. The relationship is:
Directory 1: Module 1: Create a Kubernetes cluster
Directory 7: Module 2: Deploy an app
Directory 4: Module 3: Explore your app
Directory 8: Module 4: Expose your app publicly
Directory 5: Module 5: Scale up your app
Directory 6: Module 6: Update your app
