+# Object Storage
+
+**Object Storage** is Sealos' built-in object storage service, which is primarily used to store and manage unstructured
+data.
+
+Currently, **Object Storage** has the following features:
+
+- Upload files to bucket
+- Download files from bucket
+- Expose the access permission of the bucket
+- Use SDK to access bucket
+- Monitors bucket resource metrics
+
+## Quick start
+
+### Upload files to bucket
+
+Go to Object Storage
+![](./images/1.png)
+
+Create a bucket
+![](./images/2.png)
+
+Set bucket name to test and permission to private
+![](./images/3.png)
+
+Bucket is created successfully
+![](./images/4.png)
+
+Upload file
+![](./images/5.png)
+
+File uploaded successfully
+![](./images/6.png)
+
+### Expose the access permission of the bucket
+
+Click the Edit button
+![](./images/7.png)
+
+Set Bucket Permission to publicRead and click the Application button
+![](./images/8.png)
+
+Copy file link
+![](./images/9.png)
+
+Paste to browser address bar to access files
+![](./images/10.png)
+
+### View the access key configuration
+
+An Object Storage user consists of a unique access key (username) and corresponding secret key (password). Internal is
+the internal access address of Object Storage, and External is the external access address of Object Storage.

+
+### Use SDK to access bucket
+
+The SDK requires three parameters to access bucket: AccessKey, SecretKey, and Endpoint (Internal or External). If the
+Region parameter is required, us-east-1 is used by default.
+
+#### Go Client SDK
+
+Detailed documentation reference: https://min.io/docs/minio/linux/developers/go/API.html
+
+Example: Use the Go Client SDK to upload the style.css file to the sv3dd7u4-test bucket, and set the endpoint to the
+external address. If the service is deployed in the K8s cluster, you can change the endpoint to the internal address.
+
+```go
+package main
+
+import (
+	"context"
+	"fmt"
+	"log"
+	"os"
+)
+import "github.com/minio/minio-go/v7"
+import "github.com/minio/minio-go/v7/pkg/credentials"
+
+func main() {
+	endpoint := "objectstorageapi.xxx.xxx.xxx"
+	accessKey := "xxxxxxxx"
+	secretKey := "xxxxxxxxxxxxxxxx"
+	// init minio client
+	minioClient, err := minio.New(endpoint, &minio.Options{
+		Creds: credentials.NewStaticV4(accessKey, secretKey, ""),
+	})
+	if err != nil {
+		log.Fatalln(err)
+	}
+	// get local file
+	file, err := os.Open("./style.css")
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	defer file.Close()
+
+	fileStat, err := file.Stat()
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	// put object
+	uploadInfo, err := minioClient.PutObject(context.Background(), "sv3dd7u4-test", "style.css", file, fileStat.Size(), minio.PutObjectOptions{ContentType: "text/css"})
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	fmt.Println("Successfully uploaded bytes: ", uploadInfo)
+}
+```
+
+File uploaded successfully

+
+#### Java Client SDK
+
+Detailed documentation reference: https://min.io/docs/minio/linux/developers/java/API.html
+
+Example: Use the Java Client SDK to upload the style1.css file to the sv3dd7u4-test bucket, and set the endpoint to the
+external address. If the service is deployed in the K8s cluster, you can change the endpoint to the internal address.
+
+```xml
+
+<dependency>
+    <groupId>io.minio</groupId>
+    <artifactId>minio</artifactId>
+    <version>8.5.9</version>
+</dependency>
+```
+
+```javascript
+package org.example;
+
+import io.minio.MinioClient;
+import io.minio.UploadObjectArgs;
+
+public class FileUploader {
+    public static void main(String[] args) throws Exception {
+
+        MinioClient minioClient =
+                MinioClient.builder()
+                        .endpoint("https://objectstorageapi.xxx.xxx.xxx")
+                        .credentials("xxxxxxxx", "xxxxxxxxxxxxxxxx")
+                        .build();
+
+
+        minioClient.uploadObject(
+                UploadObjectArgs.builder()
+                        .bucket("sv3dd7u4-test")
+                        .object("style1.css")
+                        .filename("src/main/java/org/example/style1.css")
+                        .build());
+
+        System.out.println("Successfully uploaded bytes.");

+# 对象存储
+
+「对象存储」是 Sealos 内置的对象存储服务，主要用于存储和管理非结构化数据。
+
+目前「对象存储」具备以下功能：
+
+- 上传文件到「存储桶」
+- 从「存储桶」下载文件
+- 公开「存储桶」的访问权限
+- 使用 SDK 访问「存储桶」
+- 监控「存储桶」资源指标
+
+## 快速开始
+
+### 上传文件
+
+进入「对象存储」
+![](./images/1.png)
+
+创建「存储桶」
+![](./images/2.png)
+
+设置「存储桶」名字为 test，权限为 private
+![](./images/3.png)
+
+「存储桶」创建成功
+![](./images/4.png)
+
+上传文件
+![](./images/5.png)
+
+上传文件成功
+![](./images/6.png)
+
+### 公开「存储桶」的访问权限
+
+点击「编辑」
+![](./images/7.png)
+
+设置「存储桶权限」为 publicRead，点击「应用」
+![](./images/8.png)
+
+复制文件链接
+![](./images/9.png)
+
+粘贴到浏览器地址栏访问文件
+![](./images/10.png)
+
+### 查看访问密钥配置
+
+对象存储用户由唯一的 Access Key（用户名）和对应的 Secret Key（密码）组成。Internal 为对象存储的内部访问地址，External
+为对象存储的外部访问地址。
+![](./images/11.png)
+
+### 使用 SDK 访问「存储桶」
+
+SDK 访问「存储桶」需要三个参数：AccessKey、SecretKey、Endpoint。参数都在访问密钥中，Internal 是内网地址 Endpoint，External 是外网地址
+Endpoint。如果需要使用 Region 参数，默认使用 us-east-1。
+
+#### Go Client SDK
+
+详细文档参考：https://min.io/docs/minio/linux/developers/go/API.html
+
+例子：使用 Go Client SDK 上传 style.css 文件到 sv3dd7u4-test 存储桶，将 Endpoint 设置为外网地址 External。如果服务部署在当前
+K8s 集群内，可以将 Endpoint 改为内网地址 Internal。
+
+```go
+package main
+
+import (
+	"context"
+	"fmt"
+	"log"
+	"os"
+)
+import "github.com/minio/minio-go/v7"
+import "github.com/minio/minio-go/v7/pkg/credentials"
+
+func main() {
+	endpoint := "objectstorageapi.xxx.xxx.xxx"
+	accessKey := "xxxxxxxx"
+	secretKey := "xxxxxxxxxxxxxxxx"
+	// init minio client
+	minioClient, err := minio.New(endpoint, &minio.Options{
+		Creds: credentials.NewStaticV4(accessKey, secretKey, ""),
+	})
+	if err != nil {
+		log.Fatalln(err)
+	}
+	// get local file
+	file, err := os.Open("./style.css")
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	defer file.Close()
+
+	fileStat, err := file.Stat()
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	// put object
+	uploadInfo, err := minioClient.PutObject(context.Background(), "sv3dd7u4-test", "style.css", file, fileStat.Size(), minio.PutObjectOptions{ContentType: "text/css"})
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	fmt.Println("Successfully uploaded bytes: ", uploadInfo)
+}
