Possibility to use as not only read-only gateway

[andrew-demb]

Thanks for the package.

We want to use all current features of nginx-s3-gateway, but also to use it to be a proxy for mutation requests (put file, delete file, etc) from the internal network from applications too.

We used minio before, but they deprecated gateway mode support and we currently searching alternative solution.

Necessary features for us for mutation requests:

• hide from the application real credentials to the cloud S3, cloud provider
• don't initiate connections to the external cloud S3 from the stateless application (PHP)

As we found in the codebase [1][2] there is no support at the current moment.

Is it possible to add support for mutating requests in nginx-s3-gateway or it is totally out of scope?

Thanks in advance.

Hi @andrew-demb , it is something that we have wanted to add for a while. It is just a matter of doing the work and teasing out the issues.

Note to self or other future implementors: the feature we will probably need to use to accomplish this with v4 AWS auth signatures is Unsigned-Payload.
