<!--
`kubeadm join phase` enables you to invoke atomic steps of the join process.
Hence, you can let kubeadm do some of the work and you can fill in the gaps
if you wish to apply customization.
-->
`kubeadm join phase` 使您能够调用 `join` 过程的基本原子步骤。因此，如果希望执行自定义操作，可以让 kubeadm 做一些工作，然后由用户来补足剩余操作。

<!--
`kubeadm join phase` is consistent with the [kubeadm join workflow](/docs/reference/setup-tools/kubeadm/kubeadm-join/#join-workflow),
and behind the scene both use the same code.
-->
`kubeadm join phase` 与 [kubeadm join 工作流程](/docs/reference/setup-tools/kubeadm/kubeadm-join/#join-workflow) 一致，后台都使用相同的代码。

## What's next
-->
## 下一步
<!--
* [kubeadm init](/docs/reference/setup-tools/kubeadm/kubeadm-init/) to bootstrap a Kubernetes control-plane node
* [kubeadm join](/docs/reference/setup-tools/kubeadm/kubeadm-join/) to connect a node to the cluster
* [kubeadm reset](/docs/reference/setup-tools/kubeadm/kubeadm-reset/) to revert any changes made to this host by `kubeadm init` or `kubeadm join`
* [kubeadm alpha](/docs/reference/setup-tools/kubeadm/kubeadm-alpha/) to try experimental functionality
-->
* [kubeadm init](/docs/reference/setup-tools/kubeadm/kubeadm-init/) 引导 Kubernetes 控制平面节点
* [kubeadm join](/docs/reference/setup-tools/kubeadm/kubeadm-join/) 将节点连接到集群
* [kubeadm reset](/docs/reference/setup-tools/kubeadm/kubeadm-reset/) 恢复通过 `kubeadm init` 或 `kubeadm join` 操作对主机所做的任何更改
* [kubeadm alpha](/docs/reference/setup-tools/kubeadm/kubeadm-alpha/) 尝试实验性功能
