Is there a server that provides an Amazon S3 style API locally? [closed]
Solution 1:
Minio will be useful for this. Written in Go and simple to deploy.
Binary downloads here: https://min.io/download
To run as as an S3 server:
minio server path/to/disk/storage
Access key and secret will be output to the console.
Solution 2:
This is possible via OpenStack Object Storage (code-named Swift), which is open source software for creating redundant, scalable object storage using clusters of standardized servers, specifically its recently added (optional) S3 API layer, which emulates the S3 REST API on top of Object Storage.
See Configuring Object Storage with the S3 API for the official documentation - a more insightful and illustrated small tutorial regarding the entire setup is available in S3 APIs on OpenStack Swift (which builds on the more complex Installing an OpenStack Swift cluster on EC2 though).
Update
An noteworthy alternative is Ceph, which is a unified, distributed storage system designed for excellent performance, reliability and scalability - interestingly it provides all three common storage models, i.e. Object Storage, Block Storage and a File System and the RADOS Gateway provides Amazon S3 and OpenStack Swift compatible interfaces to the RADOS object store [emphasis mine], see RADOS S3 API for details on currently supported S3 API features.
Solution 3:
We ran into the problem of testing our S3 based code locally and actually implemented a small Java server, which emulates the S3 object API. As it might be useful to others, we setup a github repo along with a small website: http://s3ninja.net - all OpenSource under the MIT license.
Being quite simple and minimalistic, this tool is perfect for testing and developement purposes. However, to use in in production, one might want to add some security (altough the AWS hashes are already verified in the API - just the GUI is completely unprotected). Also, it doesn't do any replication or scaling. So this wouldn't be a good choice for large setups.
