Owner

Goal

Replace the Docker-based newt and newt-appdata containers on vega with NixOS-managed multi-instance services.

Acceptance Checklist

Add a custom multi-instance Newt module.
Define a shared endpoint and per-instance environment files.
Add the SOPS secrets for the default and appdata Newt instances.
Start the native Newt instances successfully.
Confirm Pangolin shows the native instances online.
Stop the Docker Newt containers only after the native services are healthy.

Target Shape

services.nimmo.newt = {
  enable = true;
  endpoint = "https://pangolin.nimmog.uk";

  instances = {
    default.environmentFile = config.sops.secrets."newt/vega/default/env".path;
    appdata.environmentFile = config.sops.secrets."newt/vega/appdata/env".path;
  };
};

Verification

systemctl status newt-default.service
systemctl status newt-appdata.service
journalctl -u newt-default.service -n 100 --no-pager
journalctl -u newt-appdata.service -n 100 --no-pager

Notes

The issue should preserve both Pangolin organisations and avoid a blind cutover.
