This page explains how to upgrade a Windows node [created with kubeadm](/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes).

|

本页解释如何升级[用 kubeadm 创建的](/zh/docs/tasks/administer-cluster/kubeadm/adding-windows-nodes)
|

<!--
|
||||
* Familiarize yourself with [the process for upgrading the rest of your kubeadm
|
||||
cluster](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade). You will want to
|
||||
upgrade the control plane nodes before upgrading your Windows nodes.
|
||||
-->
|
||||
* 熟悉[更新 kubeadm 集群中的其余组件](/zh/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade)。
|
||||
在升级你的 Windows 节点之前你会想要升级控制面节点。

|
||||
## Upgrading worker nodes
|
||||
|
||||
### Upgrade kubeadm
|
||||
-->
|
||||
## 升级工作节点 {#upgrading-worker-nodes}
|
||||
|
||||
### 升级 kubeadm {#upgrade-kubeadm}
|
||||
|
||||
<!--
|
||||
1. From the Windows node, upgrade kubeadm:
|
||||
|
||||
```powershell
|
||||
# replace {{< param "fullversion" >}} with your desired version
|
||||
curl.exe -Lo C:\k\kubeadm.exe https://dl.k8s.io/{{< param "fullversion" >}}/bin/windows/amd64/kubeadm.exe
|
||||
```
|
||||
-->
|
||||
1. 在 Windows 节点上升级 kubeadm：
|
||||
|
||||
```powershell
|
||||
# 将 {{< param "fullversion" >}} 替换为你希望的版本
|
||||
curl.exe -Lo C:\k\kubeadm.exe https://dl.k8s.io/{{< param "fullversion" >}}/bin/windows/amd64/kubeadm.exe
|
||||
```
|
||||
|
||||
<!--
|
||||
### Drain the node
|
||||
|
||||
1. From a machine with access to the Kubernetes API,
|
||||
prepare the node for maintenance by marking it unschedulable and evicting the workloads:
|
||||
|
||||
```shell
|
||||
# replace <node-to-drain> with the name of your node you are draining
|
||||
kubectl drain <node-to-drain> -ignore-daemonsets
|
||||
```
|
||||
|
||||
You should see output similar to this:
|
||||
|
||||
```
|
||||
node/ip-172-31-85-18 cordoned
|
||||
node/ip-172-31-85-18 drained
|
||||
```
|
||||
-->
|
||||
### 腾空节点 {#drain-the-node}
|
||||
|
||||
1. 在一个能访问到 Kubernetes API 的机器上，将 Windows 节点标记为不可调度并
|
||||
驱逐其上的所有负载，以便准备节点维护操作：
|
||||
|
||||
```shell
|
||||
# 将 <要腾空的节点> 替换为你要腾空的节点的名称
|
||||
kubectl drain <要腾空的节点> -ignore-daemonsets
|
||||
```
|
||||
|
||||
你应该会看到类似下面的输出：
|
||||
|
||||
```
|
||||
node/ip-172-31-85-18 cordoned
|
||||
node/ip-172-31-85-18 drained
|
||||
```
|
||||
|
||||
<!--
|
||||
### Upgrade the kubelet configuration
|
||||
|
||||
1. From the Windows node, call the following command to sync new kubelet configuration:
|
||||
|
||||
```powershell
|
||||
kubeadm upgrade node
|
||||
```
|
||||
-->
|
||||
### 升级 kubelet 配置 {#upgrade-the-kubelet-configuration}
|
||||
|
||||
1. 在 Windows 节点上，执行下面的命令来同步新的 kubelet 配置：
|
||||
|
||||
```powershell
|
||||
kubeadm upgrade node
|
||||
```
|
||||
|
||||
<!--
|
||||
### Upgrade kubelet
|
||||
|
||||
1. From the Windows node, upgrade and restart the kubelet:
|
||||
|
||||
```powershell
|
||||
stop-service kubelet
|
||||
curl.exe -Lo C:\k\kubelet.exe https://dl.k8s.io/{{< param "fullversion" >}}/bin/windows/amd64/kubelet.exe
|
||||
restart-service kubelet
|
||||
```
|
||||
-->
|
||||
### 升级 kubelet {#upgrade-kubelet}
|
||||
|
||||
1. 在 Windows 节点上升级并重启 kubelet：
|
||||
|
||||
```powershell
|
||||
stop-service kubelet
|
||||
curl.exe -Lo C:\k\kubelet.exe https://dl.k8s.io/{{< param "fullversion" >}}/bin/windows/amd64/kubelet.exe
|
||||
restart-service kubelet
|
||||
```
|
||||
|
||||
<!--
|
||||
### Uncordon the node
|
||||
|
||||
1. From a machine with access to the Kubernetes API,
|
||||
bring the node back online by marking it schedulable:
|
||||
|
||||
```shell
|
||||
# replace <node-to-drain> with the name of your node
|
||||
kubectl uncordon <node-to-drain>
|
||||
```
|
||||
-->
|
||||
### 对节点执行 uncordon 操作 {#uncordon-the-node}
|
||||
|
||||
1. 从一台能够访问到 Kubernetes API 的机器上，通过将节点标记为可调度，使之
|
||||
重新上线：
|
||||
|
||||
```shell
|
||||
# 将 <要腾空的节点> 替换为你的节点名称
|
||||
kubectl uncordon <要腾空的节点>
|
||||
```
|
||||
|
||||
<!--
|
||||
### Upgrade kube-proxy
|
||||
|
||||
1. From a machine with access to the Kubernetes API, run the following,
|
||||
again replacing {{< param "fullversion" >}} with your desired version:
|
||||
|
||||
```shell
|
||||
curl -L https://github.com/kubernetes-sigs/sig-windows-tools/releases/latest/download/kube-proxy.yml | sed 's/VERSION/{{< param "fullversion" >}}/g' | kubectl apply -f -
|
||||
```
|
||||
-->
|
||||
### 升级 kube-proxy {#upgrade-kube-proxy}
|
||||
|
||||
1. 在一台可访问 Kubernetes API 的机器上和，将 {{< param "fullversion" >}} 替换成你
|
||||
期望的版本后再次执行下面的命令：
|
||||
|
||||
```shell
|
||||
curl -L https://github.com/kubernetes-sigs/sig-windows-tools/releases/latest/download/kube-proxy.yml | sed 's/VERSION/{{< param "fullversion" >}}/g' | kubectl apply -f -
|
||||
```
