Overview

This application is a variant of crossfiresync that implements the application in Cloud Run instead of a Cloud Function. This is accomplished by utilizing the exact same logic and implementation and simply wrapping that with Spring Boot 3 and allowing that to be built as a Docker container.

Getting Started

This Container for the most recent development version is available on GitHub Packages:

docker pull ghcr.io/unitvectory-labs/crossfiresyncrun:dev

APIs

The implementation for crossfiresyncrun has one endpoint for receiving the events from Firestore and another for receiving events from Pub/Sub via Eventarc.

The /firestore endpoint receives the google.cloud.firestore.document.v1.written events from Eventarc.

The /pubsub endpoint receives the google.cloud.pubsub.topic.v1.messagePublished events from Eventarc.
