What I want to achieve

I am trying to setup an Eventarc trigger. A specific Firestore action (deletion of a document) should trigger a Cloud Run service instance.

My problem

The service should be provided in europe but...

Eventarc is only supported in the following regions:

  • europe-north1
  • europe-west1
  • europe-west4

(https://cloud.google.com/eventarc/docs/locations#europe)

Firestore is only supported in the following regions:

  • europe-west2
  • europe-west3
  • europe-west6
  • europe-central12

(https://firebase.google.com/docs/firestore/locations)

When I tried setting up the trigger on the Cloud Run Service, it prompted me to select a region from where (i.e. the region) the trigger should originate and receive events from. My Firestore region is set to europe-west3. Since Eventarc is not supported in this region I was trying to find our if I can get Firestore into a supported Eventarc region in Europe but there is literally none. Does that theoretically mean that Eventarc does not support Firestore in Europe at all?

There is the option to select all regions but I assume that this just means receiving events from all the supported regions, right?

Is there any way I can get this working or any official plans from Google about when to support this?

since the region is not supported by Eventarc right now, your only option is to create a global trigger. As you mentioned, this will trigger will get events from all regions. Eventarc will be adding new regions soon but I don't have details on what exact regions.
