# Loki — the single log store for the whole Thermograph fleet: prod and beta
|
|
# (both on vps2, as separate Swarm stacks) and dev (vps1, mesh-only, its own
|
|
# compose project). Every node's Alloy agent pushes here over the WireGuard
|
|
# mesh; Grafana reads from here. Single-binary, filesystem-backed: no object
|
|
# storage, no clustering — right for a three-node hobby fleet, and everything
|
|
# lives on one volume you can back up or blow away.
