<!--
Kubernetes {{< glossary_tooltip text="nodes" term_id="node" >}} come pre-populated
with a standard set of {{< glossary_tooltip text="labels" term_id="label" >}}.

You can also set your own labels on nodes, either through the kubelet configuration or
using the Kubernetes API.
-->
Kubernetes {{< glossary_tooltip text="节点" term_id="node" >}}预先填充了一组标准
{{< glossary_tooltip text="标签" term_id="label" >}}。

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

Kubernetes 在节点上设置的预设标签有：

<!--

<!--
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.
-->
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，`kubernetes.io/hostname` 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。
