## Repository Archive Storage (`storage.repo-archive`)
Configuration for repository archive storage. It will inherit from default `[storage]` or
`[storage.xxx]` when set `STORAGE_TYPE` to `xxx`. The default of `PATH`
is `data/repo-archive` and the default of `MINIO_BASE_PATH` is `repo-archive/`.
- `STORAGE_TYPE`: **local**: Storage type for repo archive, `local` for local disk or `minio` for s3 compatible object storage service or other name defined with `[storage.xxx]`
- `SERVE_DIRECT`: **false**: Allows the storage driver to redirect to authenticated URLs to serve files directly. Currently, only Minio/S3 is supported via signed URLs, local does nothing.
- `PATH`: **./data/repo-archive**: Where to store archive files, only available when `STORAGE_TYPE` is `local`.
- `MINIO_ENDPOINT`: **localhost:9000**: Minio endpoint to connect only available when `STORAGE_TYPE` is `minio`
- `MINIO_ACCESS_KEY_ID`: Minio accessKeyID to connect only available when `STORAGE_TYPE` is `minio`
- `MINIO_SECRET_ACCESS_KEY`: Minio secretAccessKey to connect only available when `STORAGE_TYPE is` `minio`
- `MINIO_BUCKET`: **gitea**: Minio bucket to store the lfs only available when `STORAGE_TYPE` is `minio`
- `MINIO_LOCATION`: **us-east-1**: Minio location to create bucket only available when `STORAGE_TYPE` is `minio`
- `MINIO_BASE_PATH`: **repo-archive/**: Minio base path on the bucket only available when `STORAGE_TYPE` is `minio`
- `MINIO_USE_SSL`: **false**: Minio enabled ssl only available when `STORAGE_TYPE` is `minio`
## Other (`other`)
- `SHOW_FOOTER_BRANDING`: **false**: Show Gitea branding in the footer.

然后你在 `[attachment]`, `[lfs]` 等中可以把这个名字用作 `STORAGE_TYPE` 的值。
## Repository Archive Storage (`storage.repo-archive`)
Repository archive 的存储配置。 如果 `STORAGE_TYPE` 为空,则此配置将从 `[storage]` 继承。如果不为 `local` 或者 `minio` 而为 `xxx` 则从 `[storage.xxx]` 继承。当继承时, `PATH` 默认为 `data/repo-archive``MINIO_BASE_PATH` 默认为 `repo-archive/`
- `STORAGE_TYPE`: **local**: Repository archive 的存储类型,`local` 将存储到磁盘,`minio` 将存储到 s3 兼容的对象服务。
- `SERVE_DIRECT`: **false**: 允许直接重定向到存储系统。当前,仅 Minio/S3 是支持的。
- `PATH`: 存放 Repository archive 上传的文件的地方,默认是 `data/repo-archive`
- `MINIO_ENDPOINT`: **localhost:9000**: Minio 地址,仅当 `STORAGE_TYPE``minio` 时有效。
- `MINIO_ACCESS_KEY_ID`: Minio accessKeyID仅当 `STORAGE_TYPE``minio` 时有效。
- `MINIO_SECRET_ACCESS_KEY`: Minio secretAccessKey仅当 `STORAGE_TYPE``minio` 时有效。
- `MINIO_BUCKET`: **gitea**: Minio bucket仅当 `STORAGE_TYPE``minio` 时有效。
- `MINIO_LOCATION`: **us-east-1**: Minio location ,仅当 `STORAGE_TYPE``minio` 时有效。
- `MINIO_BASE_PATH`: **repo-archive/**: Minio base path ,仅当 `STORAGE_TYPE``minio` 时有效。
- `MINIO_USE_SSL`: **false**: Minio 是否启用 ssl ,仅当 `STORAGE_TYPE``minio` 时有效。
## Other (`other`)
- `SHOW_FOOTER_BRANDING`: 为真则在页面底部显示Gitea的字样。
