# yandex_serverless_container_iam_binding (Resource)

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

{% note warning %}

**Warning:** This resource is authoritative for the given `role` on the target `container` and manages the complete set of its members. When you change or delete `yandex_serverless_container_iam_binding`, the `role` may be removed from other subjects on the `container` 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 Serverless Container IAM Binding.
//
resource "yandex_serverless_container_iam_binding" "container-iam" {
  container_id = "your-container-id"
  role         = "serverless.containers.invoker"

  members = [
    "system:allUsers",
  ]
}
```
