Google Cloud Storage source
This event source receives change notifications from a Google Cloud Storage bucket by subscribing to a Google Cloud Pub/Sub topic.
With tmctl:
tmctl create source googlecloudstorage --bucket <bucket> --pubsub.project <project> --serviceAccountKey $(cat ./key.txt)

metadata:
name: sample
spec:
bucket: my-bucket
pubsub:
project: my-project
# Alternatively, provide a pre-existing Pub/Sub topic:

Prerequisite(s)
- Event Source for Google Cloud Pub/Sub
- Storage Bucket
- Notification Configuration
Event Source for Google Cloud Pub/Sub
Change notifications from Cloud Storage buckets can not be consumed directly, but are instead sent to a Google Cloud Pub/Sub topic. Follow the instructions at Event Source for Google Cloud Pub/Sub for setting up a Pub/Sub topic and running an instance of the Pub/Sub event source.
Note
As an alternative to a manual creation, the Pub/Sub topic will be created automatically while enabling the Notification Configuration if it doesn't already exist.
Storage Bucket
You can create a Cloud Storage bucket by following the instructions from the Cloud Storage How-To Guides.
Notification Configuration
Change notifications need to be enabled in the selected bucket by applying a notification configuration. Follow the
instructions at Using Pub/Sub notifications for Cloud Storage to add a new notification
configuration using the gsutil command-line tool.
Below is an example of command which applies a notification configuration to a bucket called eventsource-dev, with a
Pub/Sub topic called triggermesh-storage-source set as event destination.
