# 持久化存储

## 在 Helm Chart 值中查找持久化存储库配置

### 显示 Helm Chart 值

```bash theme={null}
helm show values dify/dify
```

## 在 Helm Chart 值中查找持久化存储配置

这是 Helm chart 值中持久化存储配置的示例。

```yaml theme={null}
persistence:
  type: "s3"
  s3:
    endpoint: "https://xxx.r2.cloudflarestorage.com"
    accessKey: "#REPLACE_ME#"
    secretKey: "#REPLACE_ME#"
    region: "us-east-1"
    bucketName: "your-bucket-name"
    addressType: ""
    useAwsManagedIam: false
  ... ...
```

## `persistence.type` 字段的选项

* s3
* azure-blob
* aliyun-oss
* google-storage
* tencent-cos

## 如何使用 IAM 角色配置 Amazon S3 存储

如果你想使用 AWS IAM 角色访问 S3 存储桶，可以在 Helm chart 值中将 `useAwsManagedIam` 字段设置为 `true`。`region` 和 `bucketName` 字段是必需的。

```yaml theme={null}
persistence:
  type: "s3"
  s3:
    endpoint: "https://s3.xxxxx.amazonaws.com"
    region: "us-east-1"
    bucketName: "your-bucket-name"
    useAwsManagedIam: true
```
