Google Cloud Storage Default Object Access Control

This page shows how to write Terraform for Cloud Storage Default Object Access Control and write them securely.

google_storage_default_object_access_control (Terraform)

The Default Object Access Control in Cloud Storage can be configured in Terraform with the resource name google_storage_default_object_access_control. The following sections describe 2 examples of how to use the resource and its parameters.

Example Usage from GitHub
resource "google_storage_default_object_access_control" "private-rule" {
  bucket =
  entity = ""
  role   = "OWNER"
resource "google_storage_default_object_access_control" "public" {
  bucket =
  role   = "READER"
  entity = "allUsers"

The name of the bucket.

  • domain optional computed - string

The domain associated with the entity.

  • email optional computed - string

The email address associated with the entity.

The entity holding the permission, in one of the following forms: user-[[userId]] user-[[email]] (such as "") group-[[groupId]] group-[[email]] (such as "") domain-[[domain]] (such as "") project-team-[[projectId]] allUsers allAuthenticatedUsers

The ID for the entity

The content generation of the object, if applied to an object.

  • id optional computed - string
  • object optional - string

The name of the object, if applied to an object.

The project team associated with the entity

The access permission for the entity. Possible values: ["OWNER", "READER"]

Explanation in Terraform Registry

The DefaultObjectAccessControls resources represent the Access Control Lists (ACLs) applied to a new object within a Google Cloud Storage bucket when no ACL was provided for that object. ACLs let you specify who has access to your bucket contents and to what extent. There are two roles that can be assigned to an entity: READERs can get an object, though the acl property will not be revealed. OWNERs are READERs, and they can get the acl property, update an object, and call all objectAccessControls methods on the object. The owner of an object is always an OWNER. For more information, see Access Control, with the caveat that this API uses READER and OWNER instead of READ and FULL_CONTROL. To get more information about DefaultObjectAccessControl, see:

Tips: Best Practices for The Other Google Cloud Storage Resources

In addition to the google_storage_bucket, Google Cloud Storage has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.



Ensure uniform bucket-level access of your GCS bucket is enabled

It is better to enable uniform bucket-level access of the GCS bucket. Uniform bucket-level access unifies and simplifies how you grant access to resources in the bucket.

Review your Google Cloud Storage settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.
