google_storage_notification

Creates a new notification configuration on a specified bucket, establishing a flow of event notifications from GCS to a Cloud Pub/Sub topic. For more information see the official documentation and API.

Example Usage

resource "google_storage_bucket" "bucket" {
    name = "default_bucket"
}

resource "google_pubsub_topic" "topic" {
    name = "default_topic"
}

// In order to enable notifications,
// a GCS service account unique to each project
// must have the IAM permission "projects.topics.publish" to a Cloud Pub/Sub topic from this project
// The only reference to this requirement can be found here:
// https://cloud.google.com/storage/docs/gsutil/commands/notification
// The GCS service account has the format of <project-id>@gs-project-accounts.iam.gserviceaccount.com
// API for retrieving it https://cloud.google.com/storage/docs/json_api/v1/projects/serviceAccount/get

resource "google_pubsub_topic_iam_binding" "binding" {
    topic       = "${google_pubsub_topic.topic.name}"
    role        = "roles/pubsub.publisher"

    members     = ["serviceAccount:[email protected]"]
}

resource "google_storage_notification" "notification" {
    bucket            = "${google_storage_bucket.bucket.name}"
    payload_format    = "JSON_API_V1"
    topic             = "${google_pubsub_topic.topic.id}"
    event_types       = ["OBJECT_FINALIZE", "OBJECT_METADATA_UPDATE"]
    custom_attributes {
        new-attribute = "new-attribute-value"
    }
    depends_on        = ["google_pubsub_topic_iam_binding.binding"]
}
