# ubuntu

**Role:** Primary Docker host — runs ~70 containers for the homelab
**IP:** 192.168.50.61
**Hostname:** ubuntu
**Uptime:** 5 days, 11h (as of 2026-04-28)
**CPU Load:** 7.44 (elevated — investigate if persistent)

## Overview

ubuntu is the workhorse of the homelab — a beefy Intel NUC or server-class machine running Ubuntu with Docker. It hosts approximately 70 containers including authentik SSO, the full monitoring stack, media automation (Sonarr/Radarr/Prowlarr), AI services (whisper, qdrant, reccollection), and the primary Traefik reverse proxy.
