Description

The google_cloud_identity_group_membership resource lacks a feature to ignore errors when attempting to create a membership that already exists. In certain situations, such as running Terraform against existing infrastructure or when managing external systems, it is beneficial to have a create_ignore_already_exists flag to prevent errors from failing the entire run.

New or Affected Resource(s)

• google_cloud_identity_group_membership

Potential Terraform Configuration

resource "google_cloud_identity_group_membership" "example" {
  group      = "groups/[email protected]"
  preferred_member_key {
    id = "user:[email protected]"
  }
  
  role = "MEMBER"

  # Proposed feature: ignore creation if the member already exists
  create_ignore_already_exists = true
}
