# Helm部署JuiceFS-CSI对接对象存储
## 介绍
**JuiceFS CSI是一个遵循CSI规范的驱动程序它实现了容器编排系统与JuiceFS文件系统之间的接口使得Kubernetes集群能够以持久卷的形式提供给Pod使用**
## 开始部署
> 提前准备 Minio 和 Mysql 数据库
| 服务名 | 服务器地址:端口 | 存储库名 | 账户/密码 |
| :----: | :---------------: | :------: | :-----------------------: |
| Mysql | 192.168.1.10:3306 | juicefs | root:root |
| Minio | 192.168.1.20:9000 | juicefs | ${accessKey}/${secretKey} |
[官方Chart仓库](https://github.com/juicedata/charts/tree/main) [官方文档](https://juicefs.com/docs/zh/csi/introduction)
1. 添加仓库
```bash
helm repo add juicefs https://juicedata.github.io/charts/
helm repo update
```
2. 编辑 values.yaml 文件
```bash
vi juicefs-values.yaml
```
内容如下
```yaml
# 检查 kubelet 根目录 ps -ef | grep kubelet | grep root-dir
kubeletDir: /var/lib/kubelet
# 配置存储
storageClasses:
- name: juicefs-sc
enabled: true
reclaimPolicy: Delete
allowVolumeExpansion: true
backend:
name: "rainbond"
metaurl: "mysql://root:root@(192.168.1.10:3306)/juicefs"
storage: "s3"
# 创建 Access Keys 填写
accessKey: "${accessKey}"
secretKey: "${secretKey}"
bucket: "http://192.168.1.20:9000/juicefs?tls-insecure-skip-verify=true"
envs: "{TZ: Asia/Shanghai}"
# 关闭面板
dashboard:
enabled: false
# 配置镜像加速
sidecars:
livenessProbeImage:
repository: registry.aliyuncs.com/google_containers/livenessprobe
nodeDriverRegistrarImage:
repository: registry.aliyuncs.com/google_containers/csi-node-driver-registrar
csiProvisionerImage:
repository: registry.aliyuncs.com/google_containers/csi-provisioner
csiResizerImage:
repository: registry.aliyuncs.com/google_containers/csi-resizer
```
3. 部署
```bash
helm install juicefs juicefs/juicefs-csi-driver \
--namespace juicefs --create-namespace \
-f juicefs-values.yaml
```
## 卸载
```bash
helm uninstall juicefs -n juicefs
```
## 动态配置
> 如果想加入动态配置可在安装之前编辑此文件添加
```bash
vi juicefs-csi-driver/templates/storageclass.yaml
```
> 此处添加juicefs/clean-cache: "true"
>
```yaml
apiVersion: storage.k8s.io/v1
...
parameters:
juicefs/clean-cache: "true"
```
## 问题记录
> /var/lib/juicefs 是 juicefs 的缓存目录,请单独挂载磁盘(在本盘写满后才会清理,所以会导致 / 写满)
