# Kubernetes节点常用操作
|
||
|
||
## 允许节点加入集群
|
||
|
||
1. 查看待加入节点
|
||
|
||
```bash
|
||
kubectl get csr
|
||
```
|
||
|
||
2. 查看节点信息
|
||
|
||
```bash
|
||
kubectl describe csr $name
|
||
```
|
||
|
||
3. 批准加入
|
||
|
||
```bash
|
||
kubectl certificate approve $name
|
||
```
|
||
|
||
4. 查看结果
|
||
|
||
```bash
|
||
kubectl get csr
|
||
#CONDITION=Approved,Issued
|
||
```
|
||
|
||
## 删除节点
|
||
|
||
> 在删除节点前，要先排空节点上POD
|
||
|
||
1. 排空POD
|
||
|
||
```bash
|
||
kubectl drain <node name> --delete-local-data --force --ignore-daemonsets
|
||
```
|
||
|
||
2. 删除节点
|
||
|
||
```bash
|
||
kubectl delete node <node name>
|
||
```
|
||
|
||
## 给节点打标签
|
||
|
||
- `Master` 打标签
|
||
|
||
```bash
|
||
kubectl label node 192.168.1.10 node-role.kubernetes.io/master='k8s-master1'
|
||
```
|
||
|
||
- `Node` 打标签
|
||
|
||
```bash
|
||
kubectl label node ${node} node-role.kubernetes.io/worker=true
|
||
```
|
