Happy NixCon 2018 to all! Though I unfortunately couldn’t make it this year, I’m happy to announce a release a small project of mine at the same time, named Eris – a simple, easy-to-use binary cache for any system running Nix:
The intention of writing this was that I wanted a cache which was a bit more configurable and usable than the venerable
nix-serve, easier than a raw S3 bucket – yet not as complex as setting up a full-blown Hydra instance, for local office and (authenticated) remote deployments.
There is extensive documentation on how to use it in the readme file, which should more-or-less outline everything you might want to know for signing, authentication, and deploying it.
I hope this is useful to others in the event they need a simple cache server to integrate with their deployment setup. Please feel free to file bugs and feature requests; there are surely a few things I’ve missed.
 There is only a small amount of code, which was pretty easy to write, but writing all the documentation took a while! And “well documented” has historically been one of our weaker points, so I wanted to address that.
