From the docs: https://cloud.google.com/sql/docs/postgres/connect-external-app#appaccessIP https://cloud.google.com/sql/docs/postgres/connect-external-... > You can grant any application access to a Cloud SQL instance by authorizing the IP addresses that the application uses to connect. > You can not specify a private network (for example, 10.x.x.x) as an authorized network. > PostgreSQL instances support only IPv4 addresses. They are automatically configured with a static IP address.

Ah, misremembered exactly what the issue was -- you're right, individual endpoints can be whitelisted. Internal networks cannot, which is what I (or anyone else using GKE) would need, since node IPs are ephemeral. I believe the same issue would apply to VM instances that are not pets, (in auto-scaling groups for example), since I'm not aware of being able to auto-assign static IPs there either.
