Some other existing videos that showcase using devfile with other tools, e.g. devWorkspace, vscode, for reference:

In the video, focus on the operation of the devfile instead of editing the devfile:

1. odo create (say nodejs)
2. ls and highlight the devfile.yaml entry
3. odo push
4. run the app on the browser or using curl
5. Switch to devWorkspace and show start of devfile workspace
6. highlight that there is a devfile.yaml to start

6. run the app on the browser or using curl

This step would require an extra step before with odo:

odo url create --host $(minikube ip).nip.io --ingress

@elsony Probably not a big deal to skip this part in the video right?

Used OpenShift Dev Sandbox for deployment instead.
