MongoDB fails to deploy

[dascog]

Hi, I have been looking at this issue for some days and have not been able to resolve it.
Context: "Connecting to a Database" in the National Parks workshop.
Steps:

• Both the "Create Template" and "Import Image" steps seem to work without a problem.
• The "Add Database" step similarly seems to work fine except the when the database deploys it fails to scale up to 1 pod.
  Other info:
• Obviously the app itself doesn't work without a DB
• If you attempt to trigger a scale event by using the "Start Rollout" menu item, a popup appears with the error message: cannot trigger a deployment for "mongodb-nationalparks" because it contains unresolved images
  Platform:
• I am doing this on a 4.10 cluster on AWS VMs.
