Promotes the admin → System area from a single index page with a transient
overlay into a real router with four addressable sub-pages, plus a docker-
api-backed read surface to drive them.
URLs:
/admin/config/system index (gauges + trends + per-app table)
/admin/config/system/metric/<key> single-metric deep-dive
/admin/config/system/app/<name> per-container app deep-dive
/admin/config/system/storage docker disk-usage breakdown
The path resolves to category=`system` in adminCategoryFromPath, so the
existing SPA dispatch still drops you into AdminSystem; AdminSystem then
reads the rest of the path and mounts the right sub-renderer into
config-section. Each sub-page owns its own DOM + lifecycle and is disposed
when the orchestrator re-mounts on the next navigation. Browser back, page
reload, and shareable URLs all work — no modal, no overlay state, no
fragile open/close lifecycle. Esc on the metric page navigates back to the
index.
Backend (containers/libreportal/backend):
- utils/docker.js — shared client for the bind-mounted Docker socket
(extracted from service-routes.js' inline copy). dockerRequest,
dockerStream, and a multiplex-log decoder for /containers/:id/logs.
- routes/docker-info-routes.js mounted at /api/system, contributes:
GET /containers full list, plus grouped-by-app shape
GET /containers/:id inspect projection (limits, mounts,
networks, ports, health, restart count)
GET /containers/:id/stats one-shot CPU% / memory / network /
blkio / pids (derived from precpu/cpu
deltas, like `docker stats`)
GET /containers/:id/logs last N lines, multiplex-decoded
GET /storage `docker system df` rolled up per
category, plus top-10 images +
top-10 volumes by size
Frontend (containers/libreportal/frontend/js/components/admin):
- admin-system.js — refactored into orchestrator + index view. _parsePath
drives dispatch; sub-views are window.SystemMetricPage /
SystemAppPage / SystemStoragePage classes mounted into config-section.
The per-app table is now keyboard-focusable rows that navigate to the
per-container page; the Docker strip grows a "Storage" tile that
navigates to the storage page.
- system-metric-page.js (renamed from system-detail.js, rewritten as an
in-flow page renderer). Same chart visuals as the old overlay — grid,
axis, area gradient, peak/min/now markers, hover crosshair + tooltip
scrubbing, per-metric accent theming — but rendered into the page
instead of a fixed-position panel. Range picker reflects to ?range=
so refresh preserves the selection. 1 Hz SSE feed splices into the
chart tail in real time.
- system-app-page.js — for each container in the app stack: status,
image, image-id, uptime; live stats card (cpu / mem with limit-pct /
rx / tx / blkio r-w / pids, polled every 2s with warn+danger colour
cues at 80% and 95% of memory limit); limits panel (memory, cpu,
pids, restart policy, restart count, started-ago); healthcheck
status + last 3 probes; networks table (name, IP, gateway, MAC);
published ports; mounts table with type badges; collapsible log tail
with refresh.
- system-storage-page.js — donut chart (cumulative-arc, hand-rolled
SVG) splits total in-use disk by images / volumes / containers /
build cache; per-category cards with size + reclaimable; top-10
images and top-10 volumes tables with "unused" / "orphan" badges.
CSS (containers/libreportal/frontend/css/admin.css):
Overlay-specific rules (.sys-detail wrapper, backdrop, panel, close
button, body lock) removed. Inner chart rules (stats grid, svg, grid,
axes, peak/min/now, crosshair, tooltip, foot) retained and reused by
the metric page. New blocks for .sys-metric-page, .sys-app-page (with
stat warn/danger colour states, health pills, mount-type badges, log
pre styling), .sys-storage-page (donut + legend + headline + per-
category cards + orphan/unused badges), .sys-app-row (clickable
rows with arrow + accent hover), .sys-stat-link (clickable Docker
strip tile).
