# Quadlet unit: prometheus (rootless, boot-persistent).
|
|
#
|
|
# Install path on dankclaw: ~/.config/containers/systemd/prometheus.container
|
|
# Unit name: prometheus.service (container name: prometheus)
|
|
#
|
|
# The homelab metrics store. This replaces the compose service of the same
|
|
# name in dankclaw/compose.yaml ("Observability" block): these five containers
|
|
# were started by hand with podman-compose and never came back after a reboot,
|
|
# which the 2026-09-11 reboot for the amd_iommu=off change made obvious.
|
|
#
|
|
# PUBLISHING. The published port is bound to 127.0.0.1 deliberately. Prometheus
|
|
# is reached by Caddy over the dankclaw_default network (the Caddyfile's
|
|
# post-auth handler proxies to prometheus:9090) and by the host-side homepage
|
|
# status timer over 127.0.0.1. The compose service published on 0.0.0.0, which
|
|
# put an UNAUTHENTICATED metrics API — with the lifecycle endpoint enabled —
|
|
# on every host interface: a bypass around the Anubis + Authentik guard on
|
|
# prometheus.franksdank.cloud. No off-host consumer needs it.
|
|
#
|
|
# CONFIG. /opt/prometheus/config/prometheus.yml is installed from
|
|
# shared/prometheus/prometheus.yml by deploy-remote.sh on every deploy, so the
|
|
# repo copy is the source of truth. STATE (30-day retention) lives in
|
|
# /opt/prometheus/data.
|
|
#
|
|
# Rootless: container root maps to the invoking user (dank) in this user
|
|
# namespace and dank owns /opt/prometheus/data. The image's default user
|
|
# (nobody) maps to a subuid that cannot write it.
|
|
#
|
|
# RULES. Five LLM alert rules and one recording rule load from
|
|
# /etc/prometheus/rules/ (installed from shared/prometheus/rules/ by the
|
|
# deployer). Delivery went live 2026-09-17: the alerting block in
|
|
# prometheus.yml points at alertmanager:9093, which webhooks every firing
|
|
# group to the host-side Signal relay (127.0.0.1:18093, reached as
|
|
# host.containers.internal), which sends through signal-cli account 318311.
|
|
# The Grafana dashboard's ALERTS panel remains the second surface.
|
|
#
|
|
# The config volume is also why rules belong in git: editing them in the UI is
|
|
# lost on the next deploy, since the deployer overwrites the whole directory.
