Possibly of interest: s3gw[1] is a modified version of ceph's radosgw that allows it to run standalone. It's geared towards kubernetes (notably part of Rancher's storage solution), but should work as a standalone container.
Every couple years they'll define an edition of a language (e.g. rust 2015, rust 2018), the idea being that if you choose to stick to one of them, the latest rust will still compile your code as long as you tell it what version you're targetting.
