Why can't my Private Spaces app connect to private Heroku Postgres or Redis instances during deploy?
Private Spaces apps are built outside of the Spaces. This makes it impossible to reach the Private datastore protected inside the Private Space while the app is being built and deployed.
If possible, eliminate the dependency on your private datastore during build time or use a datastore in Common Runtime.
Otherwise, Pipelines maybe of your help:
- Create a pipeline and create a Common Runtime app in staging with public datastores
- Add the Private Space app in production
- Deploy to staging
- Promote the staging app to production
