Collection of resources to manage IAM policy for Compute Engine RegionBackendService

IAM policy for Compute Engine RegionBackendService

Three different resources help you manage your IAM policy for Compute Engine RegionBackendService. Each of these resources serves a different use case:

  • google_compute_region_backend_service_iam_policy: Authoritative. Sets the IAM policy for the regionbackendservice and replaces any existing policy already attached.
  • google_compute_region_backend_service_iam_binding: Authoritative for a given role. Updates the IAM policy to grant a role to a list of members. Other roles within the IAM policy for the regionbackendservice are preserved.
  • google_compute_region_backend_service_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the regionbackendservice are preserved.

~> Note: google_compute_region_backend_service_iam_policy cannot be used in conjunction with google_compute_region_backend_service_iam_binding and google_compute_region_backend_service_iam_member or they will fight over what your policy should be.

~> Note: google_compute_region_backend_service_iam_binding resources can be used in conjunction with google_compute_region_backend_service_iam_member resources only if they do not grant privilege to the same role.

~> Note: This resource supports IAM Conditions (beta) but they have some known limitations which can be found here. Please review this article if you are having issues with IAM Conditions.

~> Warning: This resource is in beta, and should be used with the terraform-provider-google-beta provider. See Provider Versions for more details on beta resources.

Argument Reference

The following arguments are supported:

  • name - (Required) Used to find the parent resource to bind the IAM policy to

  • region - (Optional) The Region in which the created backend service should reside. If it is not provided, the provider region is used. Used to find the parent resource to bind the IAM policy to. If not specified, the value will be parsed from the identifier of the parent resource. If no region is provided in the parent identifier and no region is specified, it is taken from the provider configuration.

  • project - (Optional) The ID of the project in which the resource belongs. If it is not provided, the project will be parsed from the identifier of the parent resource. If no project is provided in the parent identifier and no project is specified, the provider project is used.

  • member/members - (Required) Identities that will be granted the privilege in role. Each entry can have one of the following values:

    • allUsers: A special identifier that represents anyone who is on the internet; with or without a Google account.
    • allAuthenticatedUsers: A special identifier that represents anyone who is authenticated with a Google account or a service account.
    • user:{emailid}: An email address that represents a specific Google account. For example, [email protected] or [email protected].
    • serviceAccount:{emailid}: An email address that represents a service account. For example, [email protected].
    • group:{emailid}: An email address that represents a Google group. For example, [email protected].
    • domain:{domain}: A G Suite domain (primary, instead of alias) name that represents all the users of that domain. For example, google.com or example.com.
    • projectOwner:projectid: Owners of the given project. For example, "projectOwner:my-example-project"
    • projectEditor:projectid: Editors of the given project. For example, "projectEditor:my-example-project"
    • projectViewer:projectid: Viewers of the given project. For example, "projectViewer:my-example-project"

  • role - (Required) The role that should be applied. Only one google_compute_region_backend_service_iam_binding can be used per role. Note that custom roles must be of the format [projects|organizations]/{parent-name}/roles/{role-name}.

  • policy_data - (Required only by google_compute_region_backend_service_iam_policy) The policy data generated by a google_iam_policy data source.

  • condition - (Optional, Beta) An IAM Condition for a given binding. Structure is documented below.

The condition block supports:

  • expression - (Required) Textual representation of an expression in Common Expression Language syntax.

  • title - (Required) A title for the expression, i.e. a short string describing its purpose.

  • description - (Optional) An optional description of the expression. This is a longer text which describes the expression, e.g. when hovered over it in a UI.

~> Warning: Terraform considers the role and condition contents (title+description+expression) as the identifier for the binding. This means that if any part of the condition is changed out-of-band, Terraform will consider it to be an entirely different resource and will treat it as such.

Attributes Reference

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

  • etag - (Computed) The etag of the IAM policy.

Import

For all import syntaxes, the "resource in question" can take any of the following forms:

  • projects/{{project}}/regions/{{region}}/backendServices/{{name}}
  • {{project}}/{{region}}/{{name}}
  • {{region}}/{{name}}
  • {{name}}

Any variables not passed in the import command will be taken from the provider configuration.

Compute Engine regionbackendservice IAM resources can be imported using the resource identifiers, role, and member.

IAM member imports use space-delimited identifiers: the resource in question, the role, and the member identity, e.g.

$ terraform import google_compute_region_backend_service_iam_member.editor "projects/{{project}}/regions/{{region}}/backendServices/{{region_backend_service}} roles/compute.admin user:[email protected]"

IAM binding imports use space-delimited identifiers: the resource in question and the role, e.g.

$ terraform import google_compute_region_backend_service_iam_binding.editor "projects/{{project}}/regions/{{region}}/backendServices/{{region_backend_service}} roles/compute.admin"

IAM policy imports use the identifier of the resource in question, e.g.

$ terraform import google_compute_region_backend_service_iam_policy.editor projects/{{project}}/regions/{{region}}/backendServices/{{region_backend_service}}

-> Custom Roles: If you're importing a IAM resource with a custom role, make sure to use the full name of the custom role, e.g. [projects/my-project|organizations/my-org]/roles/my-custom-role.

User Project Overrides

This resource supports User Project Overrides.
