Closing the command-center security queue #70/#71/#72/#73/#74: rolling tags let a rebuild move under a running service with nobody approving it, and make a CVE audit ungradeable. 36 quadlet units across dankclaw, dankserver and frankbook-pro now carry tag@sha256; localhost/* builds stay exempt (their build is the pin). The pihole and copyparty pins pull the fixed builds; valkey 9.1.2 (already running) and redis 7.4.11 are pinned in place, vendor fixes TBD. New gate tests/quadlet_image_pins.bats: no unpinned registry image, no generator-rejected key anywhere. Three seams that pinned the old exact-tag law (frankbook readarr, open_webui, seerr) now require tag AND digest - strictly stronger. Quadlet Lifecycle docs: batch-abort law, entrypoint flags-only law, pin law.

# Quadlet unit: node-exporter (rootless, boot-persistent).
|
|
#
|
|
# Install path on dankclaw: ~/.config/containers/systemd/node-exporter.container
|
|
# Unit name: node-exporter.service (container name: node-exporter)
|
|
#
|
|
# Host metrics source for Prometheus. This replaces the compose service of the
|
|
# same name in dankclaw/compose.yaml ("Observability" block).
|
|
#
|
|
# HOST NAMESPACE. It must run in the host network namespace to report the
|
|
# host's own interfaces/connections, and --pid=host for the processes and
|
|
# cgroups collectors. "localhost" inside the container is therefore the host's
|
|
# loopback, which is what the homepage status timer probes.
|
|
#
|
|
# LISTEN ADDRESSES. Until 2026-09-11 this bound :9100 on every interface. It
|
|
# now binds exactly two: loopback for the homepage status probe, and the LAN
|
|
# address because Prometheus — which runs in a container on dankclaw_default —
|
|
# scrapes http://192.168.0.143:9100 (shared/prometheus/prometheus.yml,
|
|
# job "node-dankclaw"). node_exporter itself has no authentication, so keeping
|
|
# the wildcard bind off the table matters: this is the second half of the
|
|
# pairing that removes the unauthenticated observability surface, and both
|
|
# consumers are accounted for. Dankserver runs its own copy of this container
|
|
# (scraped by the "node-dankserver" job) — since 2026-09-16 as a Quadlet unit in
|
|
# the same shape (dankserver/observability/quadlet/), because the compose-only
|
|
# version it replaced had been dead for a day and a half before anyone noticed.
|
|
#
|
|
# MOUNTS. The container reads the host's /proc, /sys and / as /host/* read-only
|
|
# and is pointed at them with --path.*; it writes nothing anywhere.
