You can also set your own labels on nodes, either through the kubelet configuration or
using the Kubernetes API.

你还可以通过 kubelet 配置或使用 Kubernetes API 在节点上设置自己的标签。

## Preset labels

The preset labels that Kubernetes sets on nodes are:

## 预设标签 {#preset-labels}

Kubernetes 在节点上设置的预设标签有：

<!--
* [`kubernetes.io/arch`](/docs/reference/labels-annotations-taints/#kubernetes-io-arch)
* [`kubernetes.io/hostname`](/docs/reference/labels-annotations-taints/#kubernetesiohostname)

* [`node.kubernetes.io/instance-type`](/docs/reference/labels-annotations-taints/#nodekubernetesioinstance-type)
  (if known to the kubelet &ndash; Kubernetes may not have this information to set the label)
* [`topology.kubernetes.io/region`](/docs/reference/labels-annotations-taints/#topologykubernetesioregion)

The value of these labels is cloud provider specific and is not guaranteed to be reliable.
For example, the value of `kubernetes.io/hostname` may be the same as the node name in some environments
and a different value in other environments.

<p>这些标签的值是特定于云提供商的，并且不保证其可靠性。
例如，<code>kubernetes.io/hostname</code> 的值在某些环境中可能与节点名称相同，
而在其他环境中可能与节点名称不同。</p></div>
