## Metadata{% #metadata %}

**Id:** `terraform-tencentcloud-tke-cluster-has-public-access` 

**Provider:** TencentCloud

**Platform:** Terraform

**Severity:** Medium

**Category:** Insecure Configurations

- [Provider Reference](https://registry.terraform.io/providers/tencentcloudstack/tencentcloud/latest/docs/resources/kubernetes_cluster#public_ip_assigned)

### Description{% #description %}

In a TKE cluster, `public_ip_assigned` should be set to `false`. A `tencentcloud_kubernetes_cluster` is noncompliant if either `master_config` or `worker_config` sets `public_ip_assigned` to `true` while `internet_max_bandwidth_out` is greater than `0`. It is also noncompliant if `public_ip_assigned` is undefined and `internet_max_bandwidth_out` is greater than `0`; in such cases, `internet_max_bandwidth_out` should be set to `0` or left undefined.
