Eventarc for event routing in GCP - Mini Project: Build & Apply

Eventarc for Event Routing

📖 Scenario: You are setting up a simple event routing system in Google Cloud using Eventarc. Your goal is to route events from a Cloud Storage bucket to a Cloud Run service.

🎯 Goal: Build an Eventarc trigger that listens to events from a specific Cloud Storage bucket and routes them to a Cloud Run service.

📋 What You'll Learn

Create a Cloud Storage bucket named my-event-bucket

Create a Cloud Run service named event-receiver

Create an Eventarc trigger named storage-to-run-trigger that routes events from my-event-bucket to event-receiver

💡 Why This Matters

🌍 Real World

Eventarc helps connect event sources like Cloud Storage to serverless services like Cloud Run, enabling reactive and scalable cloud applications.

💼 Career

Understanding Eventarc is important for cloud engineers and developers building event-driven architectures on Google Cloud.

1

Create the Cloud Storage bucket

Create a Cloud Storage bucket named my-event-bucket using the gcloud command.

GCP

# Use the gcloud command to create the bucket named my-event-bucket
# Your code here

Need a hint?

Use gcloud storage buckets create followed by the bucket name.

2

Create the Cloud Run service

Create a Cloud Run service named event-receiver deployed in the us-central1 region. Use the image gcr.io/cloudrun/hello.

GCP

# Use the gcloud command to deploy the Cloud Run service named event-receiver
# Your code here

Need a hint?

Use gcloud run deploy with the service name, image, region, and allow unauthenticated access.

3

Create the Eventarc trigger

Create an Eventarc trigger named storage-to-run-trigger that listens to google.cloud.storage.object.v1.finalized events from the bucket my-event-bucket and routes them to the Cloud Run service event-receiver in us-central1.

GCP

# Use the gcloud command to create the Eventarc trigger named storage-to-run-trigger
# Your code here

Need a hint?

Use gcloud eventarc triggers create with event filters for type and bucket, and specify the destination Cloud Run service and region.

4

Verify the Eventarc trigger

List the Eventarc triggers in us-central1 to verify that the trigger storage-to-run-trigger exists.

GCP

# Use the gcloud command to list Eventarc triggers in us-central1
# Your code here

Need a hint?

Use gcloud eventarc triggers list with the --location flag.
