# yandex_datasphere_community_iam_binding (Resource)

Allows creation and management of a single binding within IAM policy for an existing `community`.

{% note warning %}

**Warning:** This resource is authoritative for the given `role` on the target `community` and manages the complete set of its members. When you change or delete `yandex_datasphere_community_iam_binding`, the `role` may be removed from other subjects on the `community` as well — including subjects granted outside of this resource (via the corresponding `*_iam_member` resource, the management console, CLI or API). Those subjects are not tracked in the Terraform state, so a plain `terraform plan` does not list them. Be careful.

{% endnote %}


## Example usage

```terraform
//
// Create a new Datasphere Community and new IAM Binding for it.
//

  description        = "Description of community"
  billing_account_id = "example-organization-id"
  labels = {
    "foo" : "bar"
  }
  organization_id = "example-organization-id"
}

  community_id = yandex_datasphere_community.my-community.id
  role         = "datasphere.communities.developer"
  members = [
    "system:allUsers",
  ]
}
