Preview deployments with docker-compose not working with depends-on

[MrGreenTea]

We're deploying our docker-compose.yml file which uses the depends-on.

On our PRs we get this error because it seems the services are renamed, but not in the depends-on field.

service "payload-pr-8" depends on unknown service "mongo"

Is there a way to get this working? On a related note, can we somehow copy data from the production volume into the preview deployment so the database is not empty?

I just found this issue that's the same problem: #2005 (comment)
