Cloud Eventarc – Pub/Sub tutorial

This sample shows how to create a service that processes Pub/Sub events using the CloudEvents SDK.

Quickstart

Deploy your Cloud Run service:

gcloud builds submit \
  --tag gcr.io/$(gcloud config get-value project)/eventarc-pubsub
gcloud run deploy eventarc-pubsub \
  --image gcr.io/$(gcloud config get-value project)/eventarc-pubsub \
  --platform managed

Create a Cloud Eventarc trigger, which will also create a Pub/Sub topic:

gcloud beta eventarc triggers create pubsub-trigger \
  --destination-run-service eventarc-pubsub \
  --matching-criteria "type=google.cloud.pubsub.topic.v1.messagePublished"

Test

Test your Cloud Run service by getting the created topic, and publishing a message to that topic:

TOPIC=$(gcloud beta eventarc triggers describe pubsub-trigger \
--format="value(transport.pubsub.topic)")

echo "Listening to events on topic: $TOPIC"

gcloud pubsub topics publish $TOPIC --message="Events"

You may observe the Run service receiving an event in Cloud Logging:

gcloud logging read "resource.type=cloud_run_revision AND \
resource.labels.service_name=eventarc-pubsub" \
  --project $(gcloud config get-value project) \
  --limit 10 \
  --format 'value(textPayload)'
