# 通过应用商店部署 Longhorn

本文将提供在 DCE 5.0 应用商店以 Addon 的图形化界面安部署 Longhorn 云原生存储系统的操作步骤及说明。

## Longhorn helm chart 格式转换

### 添加 repo

```
[root@k8s-10-6-162-31 ~]# helm search repo longhorn
NAME CHART VERSION APP VERSION DESCRIPTION
longhorn/longhorn 1.3.2 v1.3.2 Longhorn is a distributed block storage system ...
```

### 拉取 Longhorn helm chart 并解压

```
[root@k8s-10-6-162-31 ~]# helm pull longhorn/longhorn
[root@k8s-10-6-162-31 ~]# ls
anaconda-ks.cfg calico.yaml helm-v3.10.1-linux-amd64.tar.gz linux-amd64 longhorn-1.3.2.tgz rook rook-ceph-image rook-ceph-image.zip

[root@k8s-10-6-162-31 ~]# tar xvfz longhorn-1.3.2.tgz

[root@k8s-10-6-162-31 longhorn]# ls
app-readme.md Chart.yaml questions.yaml README.md templates values.yaml
```

### 将 Longhorn 的 values.yaml 转成 json 格式

```
[root@k8s-10-6-162-31 ~]# helm plugin install https://github.com/karuppiah7890/helm-schema-gen.git
karuppiah7890/helm-schema-gen info checking GitHub for tag '0.0.4'
karuppiah7890/helm-schema-gen info found version: 0.0.4 for 0.0.4/Linux/x86_64
karuppiah7890/helm-schema-gen info installed ./bin/helm-schema-gen
Installed plugin: schema-gen
[root@k8s-10-6-162-31 longhorn]# helm schema-gen values.yaml > values.schema.json
[root@k8s-10-6-162-31 longhorn]# ls
app-readme.md Chart.yaml questions.yaml README.md templates values.schema.json values.yaml
```

### 将含有 json 文件的 chart 打包压缩

```
[root@k8s-10-6-162-31 longhorn]# cd ..
[root@k8s-10-6-162-31 ~]# ls
anaconda-ks.cfg helm-v3.10.1-linux-amd64.tar.gz longhorn rook rook-ceph-image.zip

```
