• I can't recommend serious use of an all-in-one local Grafana Loki setup

  Grafana Loki is often (self-)described as 'Prometheus for logs'. Like Prometheus, it theoretically has a simple all in one local installation mode of operation (which is a type of monolithic deployment mode), where you install the Loki server binary, point it at some local disk space, and run Promtail to feed your system logs (ie, the systemd journal) into Loki. This is what we do, to supplement our central syslog server. Although you might wonder why you'd have two different centralized log collection systems, I've found that there are things I like using Grafana Loki for.

  However, I can no longer recommend running such an all-in-one Grafana Loki setup for anything serious, including what you might call 'production', and I think you should be wary about attempting to run Grafana Loki yourself in any configuration.
