Explanation in Terraform Registry
Three different resources help you manage your IAM policy for Cloud Run Service. Each of these resources serves a different use case:
google_cloud_run_service_iam_policy: Authoritative. Sets the IAM policy for the service and replaces any existing policy already attached.
google_cloud_run_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 service are preserved.
google_cloud_run_service_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the service are preserved.
google_cloud_run_service_iam_policycannot be used in conjunction with
google_cloud_run_service_iam_memberor they will fight over what your policy should be.
google_cloud_run_service_iam_bindingresources can be used in conjunction with
google_cloud_run_service_iam_memberresources only if they do not grant privilege to the same role.
