GAE 和 AWS RDS PostgreSQL 上的 Django

Question

Is it possible to use an AWS RDS PostgreSQL database with a Django app hosted on Google App Engine standard (Python 3)?

Currently, any code that tries to connect to the RDS database hangs, but I can connect to the RDS database from my machine.

Answer 1

I would point out that that from the AWS RDS documentation it's mentioned that you can to allow access to the specific subnet (VPC) with “publicly available” to an IP Range, and you can get the App Engine ranges by performing nslookups as shown here . Please keep into consideration that the IP ranges for the App Engine services change in a regular basis.

If you are not using VPCs then you should give a look to this AWS doc .

I would also suggest testing the connectivity to the GCP resources by using Compute Engine Virtual Machines, this can be performed also by using App Engine Flexible since you are able tossh into the GCE VM instance.
