Connect Google Cloud Run to MongoDB Atlas

Question

I'm evaluating a move from Google Kubernetes Engine to Google Cloud Run, to improve cost and resource efficiency within our company. I'm also in the process of transitioning our workflows from monolithic PHP and Ruby apps to a more nimble Node.js setup, using MongoDB.

For a small organization like ours, I like the idea of managed services such as Google Cloud Run and MongoDB Atlas, however, I'm concerned about the security. In MongoDB Atlas, it seems the only real security measure is to whitelist IP, which I obviously don't have access to through Google Cloud Run.

I'm definitely not a network expert, so I'm wondering if anyone has any ideas for securely connecting Cloud Run to MongoDB Atlas, while still maintaining scalability. If I have to remain on GKE, so be it, I just want to know all of my options before I move forward.

IP whitelist - by its very nature, Google Cloud Run would seem to be anti-static-IP, so this seems to be a non-starter.

I evaluated items such as Cloud NAT and Cloud VPC Peering, but from what I can tell Cloud Run does not have access to the VPC, so it seems like this wouldn't help either.

Answer 1

Cloud Run and Cloud Function have the same underlying infrastructure. Cloud Function have the capability to be connected to a VPC. Thereby, Cloud Run will support a day this capability, I hope by the end of 2019.

If you can, I just recommend you to wait!
