Cloud Storage

Grant Teleskope Access to CloudStorage

Attach the following roles to the Teleskope service account you created:

• roles/storage.objectViewer
• roles/pubsub.subscriber
• roles/pubsub.viewer

Create a PubSub Topic:

In order for Teleskope to capture new objects without causing a full scan each time, you will need to create a PubSub topic and subscriber.
