+To avoid CNI plugin-related errors, verify that you are using or upgrading to a
+container runtime that has been tested to work correctly with your version of
+Kubernetes.

+
+为了避免 CNI 插件相关的错误，需要验证你正在使用或升级到一个经过测试的容器运行时，
+该容器运行时能够在你的 Kubernetes 版本上正常工作。
+
+<!--
+For example, the following container runtimes are being prepared, or have already been prepared, for Kubernetes v1.24:

+Service issues exist for pod CNI network setup and tear down in containerd

+With containerd v1.6.0-v1.6.3, if you do not upgrade the CNI plugins and/or

+“这些问题在 containerd v1.6.4 中得到了解决。”
+
+在使用 containerd v1.6.0-v1.6.3 时，如果你不升级 CNI 插件和/或声明 CNI 配置版本，
+你可能会遇到以下 "Incompatible CNI versions" 或 "Failed to destroy network for sandbox"
+错误状况。

+
+如果因为配置版本比插件版本新，导致你的 CNI 插件版本与配置中的插件版本无法正确匹配时，

+If you're using containerd v1.6.0-v1.6.3 and encountered "Incompatible CNI
+versions" or "Failed to destroy network for sandbox" errors, consider updating
+your CNI plugins and editing the CNI config files.
+

+
+如果你使用 containerd v1.6.0-v1.6.3 并遇到 "Incompatible CNI versions" 或者
+"Failed to destroy network for sandbox" 错误，考虑更新你的 CNI 插件并编辑 CNI 配置文件。
+
+以下是针对各节点要执行的典型步骤的概述：
+
+<!--
+1. [Safely drain and cordon the

+
+1. [安全地腾空并隔离节点](/zh-cn/docs/tasks/administer-cluster/safely-drain-node/)。
+
+<!--
+2. After stopping your container runtime and kubelet services, perform the
+following upgrade operations:
+  - If you're running CNI plugins, upgrade them to the latest version.
+  - If you're using non-CNI plugins, replace them with CNI plugins. Use the
+  latest version of the plugins.
+  - Update the plugin configuration file to specify or match a version of the
+  CNI specification that the plugin supports, as shown in the following ["An
+  example containerd configuration
+  file"](#an-example-containerd-configuration-file) section.
+  - For `containerd`, ensure that you have installed the latest version (v1.0.0
+  or later) of the CNI loopback plugin.
+  - Upgrade node components (for example, the kubelet) to Kubernetes v1.24
+  - Upgrade to or install the most current version of the container runtime.
+-->
+
+2. 停止容器运行时和 kubelet 服务后，执行以下升级操作：
+  - 如果你正在运行 CNI 插件，请将它们升级到最新版本。
+  - 如果你使用的是非 CNI 插件，请将它们替换为 CNI 插件，并使用最新版本的插件。
+  - 更新插件配置文件以指定或匹配 CNI 规范支持的插件版本，
+    如后文["containerd 配置文件示例"](#an-example-containerd-configuration-file)章节所示。
+  - 对于 `containerd`，请确保你已安装 CNI loopback 插件的最新版本（v1.0.0 或更高版本）。
+  - 将节点组件（例如 kubelet）升级到 Kubernetes v1.24
+  - 升级到或安装最新版本的容器运行时。
+
+<!--
+3. Bring the node back into your cluster by restarting your container runtime
+and kubelet. Uncordon the node (`kubectl uncordon <nodename>`).
+-->
+
+3. 通过重新启动容器运行时和 kubelet 将节点重新加入到集群。取消节点隔离（`kubectl uncordon <nodename>`）。

+The following example shows a configuration for `containerd` runtime v1.6.x,
+which supports a recent version of the CNI specification (v1.0.0).
+Please see the documentation from your plugin and networking provider for
+further instructions on configuring your system.
+-->
+
+以下示例显示了 `containerd` 运行时 v1.6.x 的配置，
+它支持最新版本的 CNI 规范（v1.0.0）。
+请参阅你的插件和网络提供商的文档，以获取有关你系统配置的进一步说明。
+
+<!--
+On Kubernetes, containerd runtime adds a loopback interface, `lo`, to pods as a
+default behavior. The containerd runtime configures the loopback interface via a
+CNI plugin, `loopback`. The `loopback` plugin is distributed as part of the
+`containerd` release packages that have the `cni` designation. `containerd`
+v1.6.0 and later includes a CNI v1.0.0-compatible loopback plugin as well as
+other default CNI plugins. The configuration for the loopback plugin is done
+internally by containerd, and is set to use CNI v1.0.0. This also means that the
+version of the `loopback` plugin must be v1.0.0 or later when this newer version
+`containerd` is started.
+-->
+
+在 Kubernetes 中，作为其默认行为，containerd 运行时为 Pod 添加一个本地回路接口，`lo`。
+containerd 运行时通过 CNI 插件 `loopback` 配置本地回路接口。  
+`loopback` 插件作为 `containerd` 发布包的一部分，扮演 `cni` 角色。
+`containerd` v1.6.0 及更高版本包括与 CNI v1.0.0 兼容的 loopback 插件以及其他默认 CNI 插件。
+loopback 插件的配置由 containerd 内部完成， 并被设置为使用 CNI v1.0.0。
+这也意味着当这个更新版本的 `containerd` 启动时，`loopback` 插件的版本必然是 v1.0.0 或更高版本。

+The following bash command generates an example CNI config. Here, the 1.0.0
+value for the config version is assigned to the `cniVersion` field for use when
+`containerd` invokes the CNI bridge plugin.

+
+以下 Bash 命令生成一个 CNI 配置示例。这里，`cniVersion` 字段被设置为配置版本值 1.0.0，
+以供 `containerd` 调用 CNI 桥接插件时使用。
