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.

In order to enable notifications, a special Google Cloud Storage service account unique to the project must have the IAM permission "projects.topics.publish" for a Cloud Pub/Sub topic in the project. To get the service account's email address, use the google_storage_project_service_account datasource's email_address value, and see below for an example of enabling notifications by granting the correct IAM permission. See the notifications documentation for more details.

Example Usage

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"]
}

// Enable notifications by giving the correct IAM permission to the unique service account.

data "google_storage_project_service_account" "gcs_account" {}

resource "google_pubsub_topic_iam_binding" "binding" {
	topic       = "${google_pubsub_topic.topic.name}"
	role        = "roles/pubsub.publisher"
	members     = ["serviceAccount:${data.google_storage_project_service_account.gcs_account.email_address}"]
}

// End enabling notifications


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

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

Argument Reference

The following arguments are supported:

• bucket - (Required) The name of the bucket.

• payload_format - (Required) The desired content of the Payload. One of "JSON_API_V1" or "NONE".

• topic - (Required) The Cloud PubSub topic to which this subscription publishes. Expects either the topic name, assumed to belong to the default GCP provider project, or the project-level name, i.e. projects/my-gcp-project/topics/my-topic or my-topic.

---

• custom_attributes - (Optional) A set of key/value attribute pairs to attach to each Cloud PubSub message published for this notification subscription

• event_types - (Optional) List of event type filters for this notification config. If not specified, Cloud Storage will send notifications for all event types. The valid types are: "OBJECT_FINALIZE", "OBJECT_METADATA_UPDATE", "OBJECT_DELETE", "OBJECT_ARCHIVE"

• object_name_prefix - (Optional) Specifies a prefix path filter for this notification config. Cloud Storage will only send notifications for objects in this bucket whose names begin with the specified prefix.

Attributes Reference

In addition to the arguments listed above, the following computed attributes are exported:

• self_link - The URI of the created resource.

Import

Storage notifications can be imported using the notification id in the format <bucket_name>/notificationConfigs/<id> e.g.

$ terraform import google_storage_notification.notification default_bucket/notificationConfigs/102
