Requires a `stable` folder in the repository next to `skaffold.yaml`

[pascalwhoop]

TL;DR

this tool requires

• skaffold.yaml to be defined
• a stable folder to be present

I found both to be badly documented and we just found out through trial/error against GCP and digging into the logs. Any way we can get this documented better? Why is skaffold.yaml needed but not marked as required? And using an empty service, the below occurs
