# 安装 Kuboard
|
||||
|
||||
## 前提
|
||||
|
||||
安装 Kuboard 时，假设您已经有一个 Kubernetes 集群
|
||||
|
||||
如果没有 Kubernetes 集群：
|
||||
|
||||
* 初学者， 请参考 [安装 Kubernetes 单Master节点](install-k8s)
|
||||
* 用于生产，请参考 [安装 Kubernetes 高可用](install-kubernetes)
|
||||

||||
## 兼容性
|
||||
|
||||
|
||||
| Kubernetes 版本 | Kuboard 版本 | 兼容性 | 说明 |
|
||||
| --------------- | -------------- | ------ | ------------------------------------------------------------ |
|
||||

|
||||
| v1.12 | v1.0.0-beta.13 | <span style="font-size: 24px;">😐</span> | Kubernetes Api v1.12 尚不支持 dryRun，<br />忽略Kuboard在执行命令时的参数校验错误，可正常工作 |

## 安装
|
||||
|
||||
**获取并修改yaml文件**
|
||||
|
||||
```bash
|
||||
wget https://raw.githubusercontent.com/eip-work/eip-monitor-repository/master/dashboard/kuboard.yaml
|
||||
```
|
||||
|
||||
修改文件 Kuboard.yaml 中 Ingress 的 host 为 kuboard.yourclustername.yourdomain.com
|
||||
|
||||
**执行安装**
|
||||
|
||||
```bash
|
||||
kubectl apply -f kuboard.yaml
|
||||
```
|
||||
|
||||
## 获取 Token
|
||||
|
||||
您可以获得管理员用户、只读用户的Token
|
||||
|
||||
:::: tabs type:border-card
|
||||
|
||||
::: tab 管理员用户 lazy
|
||||
|
||||
**拥有的权限**
|
||||
|
||||
* 此Token拥有 ClusterAdmin 的权限，可以执行所有操作
|
||||
|
||||
**执行命令**
|
||||
|
||||
```bash
|
||||
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep kuboard-user | awk '{print $1}')
|
||||
```
|
||||
|
||||
**输出**
|
||||
|
||||
取输出信息中 token 字段

::: tab 只读用户 lazy
|
||||
|

**拥有的权限**
|
||||
|
||||
- view 可查看名称空间的内容
|

- system:node 可查看节点信息
|

- system:persistent-volume-provisioner 可查看存储类和存储卷声明的信息
|
||||
|
||||
**适用场景**
|
||||
|
||||
只读用户不能对集群的配置执行修改操作，非常适用于将开发环境中的 Kuboard 只读权限分发给开发者，以便开发者可以便捷地诊断问题
|

|
