+
+<!--
+This task outlines the steps needed to update your container runtime to containerd from Docker. It is applicable for cluster operators running Kubernetes 1.23 or earlier. Also  this covers an example scenario for migrating from dockershim to containerd and alternative container runtimes can be picked from this [page](https://kubernetes.io/docs/setup/production-environment/container-runtimes/).
+-->
+本任务给出将容器运行时从 Docker 改为 containerd 所需的步骤。
+此任务适用于运行 1.23 或更早版本 Kubernetes 的集群操作人员。
+同时，此任务也涉及从 dockershim 迁移到 containerd 的示例场景，
+以及可以从[此页面](/zh/docs/setup/production-environment/container-runtimes/)
+获得的其他容器运行时列表。

+  （例如：`unix:///run/containerd/containerd.sock`）。
