-Beginning with v1.8.0, kubeadm uploads the configuration of your cluster to a ConfigMap called
-`kubeadm-config` in the `kube-system` namespace, and later reads the ConfigMap when upgrading.
-This enables correct configuration of system components, and provides a seamless user experience.
+During `kubeadm init`, kubeadm uploads the `ClusterConfiguration` object to your cluster
+in a ConfigMap called `kubeadm-config` in the `kube-system` namespace. This configuration is then read during
+`kubeadm join`, `kubeadm reset` and `kubeadm upgrade`. To view this ConfigMap call `kubeadm config view`.

-从 v1.8.0 开始，kubeadm 将集群的配置上传到名为 kube-system 的 ConfigMap 对象中，对象位于 kube-system 命名空间内。并在以后的升级中读取这个 ConfigMap 配置对象。
-这样可以保证系统组件的正确配置，提供无缝的用户体验。
+在 `kubeadm init` 执行期间，kubeadm 将 `ClusterConfiguration` 对象上传到你的集群的 `kube-system` 名字空间下
+名为 `kubeadm-config` 的 ConfigMap 对象中。
+然后在 `kubeadm join`、`kubeadm reset` 和 `kubeadm upgrade` 执行期间读取此配置。 
+要查看此 ConfigMap，请调用 `kubeadm config view`。
 
 <!--
-You can execute `kubeadm config view` to view the ConfigMap. If you initialized your cluster using
-kubeadm v1.7.x or lower, you must use `kubeadm config upload` to create the ConfigMap before you
-may use `kubeadm upgrade`.
+You can use `kubeadm config print` to print the default configuration and `kubeadm config migrate` to
+convert your old configuration files to a newer version. `kubeadm config images list` and
+`kubeadm config images pull` can be used to list and pull the images that kubeadm requires.

-您可以执行 kubeadm config view 来查看 ConfigMap。如果使用 kubeadm v1.7.x 或更低版本来初始化群集，必须先使用 kubeadm config upload 创建 ConfigMap，然后才能使用 kubeadm upgrade。
+你可以使用 `kubeadm config print` 命令打印默认配置，
+并使用 `kubeadm config migrate` 命令将旧版本的配置转化成新版本。
+`kubeadm config images list` 和 `kubeadm config images pull`
+命令可以用来列出并拉取 kubeadm 所需的镜像。
 
 <!--
-In Kubernetes v1.11.0, some new commands were added. You can use `kubeadm config print-default`
-to print the default configuration and `kubeadm config migrate` to convert your old configuration
-files to a newer version. `kubeadm config images list` and `kubeadm config images pull` can be used
-to list and pull the images that kubeadm requires.
