Google Apps is a former name. Also, I mention primary domain and domain alias. It seems I have to use the primary domain. Otherwise, GCP replaces the field to the primary one. And every time Terraform plan returns a diff about it. I used domain alias for `members` arg in `google_project_iam_member` resource. `terraform apply` was succeeded. However, when I run modify other resources, I got a diff about the `google_project_iam_member` resource.

IAM policy for Spanner Instances
Three different resources help you manage your IAM policy for a Spanner instance. Each of these resources serves a different use case:
google_spanner_instance_iam_policy
: Authoritative. Sets the IAM policy for the instance and replaces any existing policy already attached.
~> Warning: It's entirely possibly to lock yourself out of your instance using google_spanner_instance_iam_policy
. Any permissions granted by default will be removed unless you include them in your config.
google_spanner_instance_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 instance are preserved.google_spanner_instance_iam_member
: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the instance are preserved.
~> Note: google_spanner_instance_iam_policy
cannot be used in conjunction with google_spanner_instance_iam_binding
and google_spanner_instance_iam_member
or they will fight over what your policy should be.
~> Note: google_spanner_instance_iam_binding
resources can be used in conjunction with google_spanner_instance_iam_member
resources only if they do not grant privilege to the same role.

Import
For all import syntaxes, the "resource in question" can take any of the following forms:
- {{project}}/{{name}}
- {{name}} (project is taken from provider project)
IAM member imports use space-delimited identifiers; the resource in question, the role, and the account, e.g.
$ terraform import google_spanner_instance_iam_member.instance "project-name/instance-name roles/viewer foo@example.com"
IAM binding imports use space-delimited identifiers; the resource in question and the role, e.g.
$ terraform import google_spanner_instance_iam_binding.instance "project-name/instance-name roles/viewer"
IAM policy imports use the identifier of the resource in question, e.g.
$ terraform import google_spanner_instance_iam_policy.instance project-name/instance-name
