<!-- 
 Device plugins run on worker
{{< glossary_tooltip term_id="node" text="Nodes">}} and provide
{{< glossary_tooltip term_id="pod" text="Pods ">}} with access to resources,
such as local hardware, that require vendor-specific initialization or setup
steps.
-->
设备插件工作在节点主机上，给 {{< glossary_tooltip term_id="pod" text="Pods ">}} 提供访问资源的权限，比如特定厂商初始化或者安装的本地硬件。
<!--more-->

<!--
Device plugins advertise resources to the
{{< glossary_tooltip term_id="kubelet" text="kubelet" >}}, so that workload
Pods can access hardware features that relate to the Node where that Pod is running.
You can deploy a device plugin as a {{< glossary_tooltip term_id="daemonset" >}},
or install the device plugin software directly on each target Node.
-->
设备插件将资源告知 {{< glossary_tooltip term_id="kubelet" text="kubelet" >}} ，以便相关节点上运行的工作负载Pod可以访问硬件功能。
