VPC Service Controls is a Google Cloud feature that lets you set up a
service perimeter and create a data transfer boundary. You can use
VPC Service Controls with Eventarc to help protect your
services.
We recommend that you protect all services when creating a service perimeter.
Eventarc Advanced
An Eventarc Advanced bus outside of a service perimeter can't
receive events from Google Cloud projects inside the perimeter. An
Eventarc Advanced bus inside of a perimeter can't route events to
a consumer outside of the perimeter.
To publish to an Eventarc Advanced bus, the source of an
event must be inside the same service perimeter as the bus.
To consume a message, an event consumer must be inside the same service
perimeter as the bus.
You can verify VPC Service Controls support for the Enrollment,
GoogleApiSource, MessageBus, and Pipeline resources by viewing platform
logs on ingress.
Eventarc Standard
In projects protected by a service perimeter, Eventarc Standard
is bound by the same limitations as Pub/Sub:
When routing events to Cloud Run destinations, you can only
create new Pub/Sub push subscriptions when the push
endpoints are set to Cloud Run services with default
run.app URLs. Custom domains don't
work.
When routing events to Workflows destinations
for which the Pub/Sub push endpoint is set to a
Workflows execution, you can only create new
Pub/Sub push subscriptions through Eventarc.
Note that the service account used for push authentication for the
Workflows endpoint must be included in the service
perimeter.
VPC Service Controls blocks the creation of Eventarc
triggers for
internal HTTP endpoints.
VPC Service Controls protection does not apply when routing events to
such destinations.
