Minio is a minimal cloud storage server for Micro Services. Written in Golang and licensed under [Apache license v2](./LICENSE). Compatible with Amazon S3 APIs.

## Description

Micro services environment provisions one Minio server per application instance. Scalability is achieved through large number of smaller personalized instances. This version of the Minio binary is built using Filesystem storage backend for magnetic and solid state disks.

## Minio Client

[Minio Client (mc)](https://github.com/minio/mc#minio-client-mc-) provides a modern alternative to Unix commands like ``ls``, ``cat``, ``cp``, ``sync``, and ``diff``. It supports POSIX compatible filesystems and Amazon S3 compatible cloud storage systems. It is entirely written in Golang.

#### How to use AWS SDK with Minio?

Please follow the documentation here - [Using aws-sdk-go with Minio server](./AWS-SDK-GO.md)

#### How to use s3cmd with Minio?
<blockquote>
Even with Signature version '4' enabled, 's3cmd' falls back to Signature version '2' for listing your buckets. Since minio server is only Signature version '4' listing your buckets with Signature version '2' fails. We have no immediate plans on supporting Signature version '2'. Please follow https://github.com/minio/minio/issues/987 to know more on this issue.
</blockquote>

`s3cmd` is currently not supported.
