官网:
MinIO 是一个基于 Go 实现的高性能、兼容 S3 协议的对象存储。它采用 GNU AGPL v3 开源协议,项目地址是 https://github.com/minio/minio 。
它适合存储海量的非结构化的数据,例如说图片、音频、视频等常见文件,备份数据、容器、虚拟机镜像等等,小到 1 KB,大到 5 TB 都可以支持。

如何设置桶的权限?
在MinIO中,可以通过设置桶策略来控制桶的访问权限。桶策略是一个JSON格式的文本文件,用于指定哪些实体(用户、组或IP地址)可以执行哪些操作(读、写、列举等)。
MinIO桶策略的基本结构如下所示:
{"Version": "2012-10-17","Statement": [{"Action": ["action1", "action2", ...],"Effect": "Allow|Deny","Principal": {"AWS": ["arn:aws:iam::account-id:user/user-name"]},"Resource": ["arn:aws:s3:::bucket-name/object-prefix", ...]},...]
}
