Testing this now for two weeks in production.
I got now three caches set up with it.

@majiir:matrix.orgMajiir Paktu How is the write path meant to be integrated? Is the idea that you script a niks3 CLI call in your CI/etc? 16:45:04

You do nix build and than call niks on the result symlink

in the recent ticket on US dependencies (https://github.com/NixOS/org/issues/232), the idea came up to maybe add an EU-based nix cache (of at least the more important bits).

that makes me wonder, do we know what approach might be best for that, e.g. w.r.t. scaling/performance?
over time, i'd learned of options including:

  • s3-likes (e.g. garage?) with a front-end like:
    • niks3
    • attic
    • a reverse proxy (used in forkOS infra)
  • snix-cache
  • harmonia
