Cloud Build notifiers are Docker images that can be run as containers on Cloud Run. When polled by a subscriber application, Cloud Build notifiers use push subscriptions to deliver messages to a configured service, such as Slack or an SMTP server.
This page provides an overview of Cloud Build notifiers.
Cloud Build notifiers
Cloud Build sends all build event updates,
along with build metadata, to Pub/Sub on the
cloud-builds topic. Cloud Build notifiers can be configured to listen to that topic, filter the messages it receives, and send messages to your service via Cloud Run.
All notifiers use a common YAML spec for configuration, stored in Cloud Storage. If your desired service requires authentication, credentials are stored in Secret Manager. Cloud Run routes your message and sends your notifications to your service.
The following diagram shows how Cloud Build interacts with other Google Cloud products, such as Pub/Sub and Cloud Run, to send notifications:
