docker安裝minio及文件上傳、刪除、下載
要搭建一個分布式文件存儲系統，聽說fastDFS能實現，于是我搜了一下fastDFS，結果半路殺出一個minio
考慮到拓展性、開發api文檔完善度、部署效率等原因我選擇了minio。
因為個人沒真正使用過fastDFS，所以不作過多評價，占個坑，以后有機會深度體驗后回來寫評測。
1. docker安裝minio步驟
第一步 查鏡像
docker search minio
第二步 拉鏡像
docker pull minio/minio
第三步 啟動容器
docker run -p 9000:9000 --name minio -d --restart=always -e “MINIO_ACCESS_KEY=admin” -e “MINIO_SECRET_KEY=admin123456” -v /home/data:/data -v /home/config:/root/.minio minio/minio server /data
第四步 登錄界面
- http//:ip+9000
- ACCESS_KEY:damin
- SECRET_KEY:admin123456
2. minio實現文件上傳、刪除、下載
項目結構
pom依賴：

上傳文件
使用postman進行測試
刪除文件
下載文件
