Add an admin-only POST /api/docker/prune-build-cache endpoint plus a Settings > Maintenance danger-zone button to reclaim disk used by the Docker build cache (image + static-site builds), which previously grew unbounded with no UI lever. Prunes unused-only (all=false) so a warm cache is preserved for apps redeploying soon. Mirrors the existing prune-images vertical slice; full en/ru i18n parity.
End-to-end extraction of the Instance concept. After this commit:
* internal/store/instances.go — DELETED
* internal/store/models.go — Instance struct gone, ProxyRoute moved here
* containers table is the single source of truth for project/stack/site
container state. instances table is dropped via DROP TABLE migration
(idempotent; re-runnable on every boot).
* Legacy tinyforge.project / tinyforge.stage / tinyforge.instance-id
Docker labels are no longer emitted; only tinyforge.workload.{id,kind},
tinyforge.role, and tinyforge.managed are stamped on new containers.
Backend rewrites:
- internal/deployer: executeDeploy + blueGreenDeploy + rollback +
promote use store.Container natively. New
removeContainer() replaces removeInstance().
enforceMaxInstances reads via
ListContainersByStageID.
- internal/reconciler: legacy tinyforge.instance-id dispatch removed;
upsertByWorkloadLabel now finds existing rows
by docker container ID first and falls back to
the deterministic workloadID:role key.
- internal/stale/scanner: Scan + new FindStaleContainers walk the
containers table; emit StaleContainer JSON.
- internal/stats/collector: ListContainers replaces ListAllInstances.
- internal/webhook/handler: workload-secret lookup tried first; falls back
to project / static_site secret column.
- internal/api: instances.go, stale.go, stats.go, stats_history.go,
projects.go, settings.go, docker.go, dns.go all read /
write through Container.
Docker layer:
- ManagedContainer exposes WorkloadID/Kind/Role from the canonical labels.
- ListContainers filters by tinyforge.managed=true.
- Network creation uses LabelManaged instead of LabelProject.
Frontend:
- Instance type is now a Container alias; .status → .state,
.last_alive_at → .last_seen_at.
- InstanceCard takes stageId as a prop (no longer derived from Instance).
- StaleContainer JSON shape rewritten: { container, workload_name, role,
days_stale }. StaleContainerCard + /containers/stale page updated.
- ProjectCard / homepage / SystemHealthCard filter by .state.
The migration loop now tolerates "no such table" alongside "duplicate
column" / "already exists" so obsolete ALTER TABLE entries targeting the
dropped instances table no-op cleanly on first boot.
Tests: store + deployer + reconciler + webhook + staticsite + notify all
still pass. Frontend svelte-check: zero errors.
First consumer migration off the instances table. The image
prune logic now walks the normalized containers.image_ref
column directly — one DB pass against a single table instead
of joining instances against projects to reconstruct the full
"image:tag" string. Demonstrates the consumer-switch pattern
the remaining read sites (proxies, stale scanner, webhook
matcher) will follow.
The legacy `projects []store.Project` parameter is kept on the
function signature for now so call sites don't change in this
commit; the underscore-discard in the body makes it explicit
that it's no longer load-bearing.
Security:
- rate limit /api/webhook routes per-IP and cap concurrent site syncs
- global SSE connection cap (256) with new sse_gate
- validate ?tail= and cap JSON log responses at 4 MiB
- strip ANSI/CSI/OSC and control bytes from streamed log lines
- redact webhook secret from request log middleware
- scrub host details from /api/health for non-admin viewers
- drop container_id from /api/system/stats/top for non-admins
- generate webhook secrets via crypto/rand; require >=32 chars on insert
- verify iid path consistency in streamContainerLogs
- LimitReader on site webhook body; reject malformed non-empty bodies
Concurrency / correctness:
- stats collector: Stop() no longer hangs without Start(), semaphore
acquired in parent loop so ctx cancellation short-circuits the queue,
in-flight tick cancellable via shared base context, zero-ts guard
- webhook handler: replace fire-and-forget goroutine with WaitGroup-tracked
workers + Drain() wired into graceful shutdown
- $derived(() => ...) mis-idiom fixed in ContainerStats / InstanceCard /
ProjectCard (returned function instead of value)
- SystemResourcesCard: rename `window` and `t` locals to avoid shadowing
globalThis.window and the i18n `t` import
Quality / performance:
- replace O(n^2) insertion sort with sort.Slice in stats top
- runMigrations only swallows duplicate-column / already-exists errors
- PruneStatsSamplesBefore wrapped in a transaction
- collapse N+1 in unusedImageStats / pruneImages to one ListAllInstances
pass; surface DB errors instead of silently treating them as inactive
- run Docker Info + DiskUsage in parallel via errgroup
- container log SSE emits `: ping` heartbeat every 20 s
- imageMatches case-insensitive on registry host (RFC behaviour)
- log warning on invalid stage tag pattern instead of silent skip
- reject malformed non-empty site webhook payloads
Frontend / i18n:
- shared formatBytes utility replaces three local copies
- statsInterval store drives dynamic "no samples / collection disabled"
copy across ContainerStats and SystemResourcesCard
- top consumers row now shows owner_name (project/stage or site name)
- drop seven `as any` casts on the Settings type; add cloudflare_api_token
write-only field
- move "Service status", "Docker daemon", "Docker unreachable",
"Proxy unreachable", "reachable", and "Docker daemon is not reachable."
strings into en/ru i18n bundles
Background collector samples CPU/memory/network/block I/O for every
instance and site on a configurable interval (default 15s, range
5-300s), persists samples to SQLite with a configurable retention
window (default 2h, range 0-24h), and skips ticks gracefully when
the Docker daemon is unreachable. Settings are reloadable without
a restart — each tick re-reads them.
New API endpoints:
- GET /api/system/stats (host snapshot: info + df)
- GET /api/system/stats/history
- GET /api/system/stats/top?by=cpu|memory
- GET /api/projects/{id}/stages/{s}/instances/{iid}/stats/history
- GET /api/sites/{id}/stats[/history]
- GET /api/sites/{id}/logs (SSE + JSON, reuses instance log streamer)
Frontend:
- ECharts added with tree-shaken imports (~180KB gzip) for
future-proof time-series/gantt/graph visualizations
- CollapsibleSection wraps all dashboard sections (system health,
daemons, system resources, static sites, projects) with
localStorage-persisted open state
- SystemResourcesCard shows capacity tiles, workload utilization
chart with 30m/2h/6h/24h window picker, disk breakdown with
reclaimable callouts, and top 5 consumers
- ContainerStats and ContainerLogs take a source discriminated union
so sites reuse the same components as instances; sites detail page
embeds both for Deno backend debugging
- Settings › Maintenance exposes collection interval + retention
- Docker-unavailable state returns 503 and renders an amber banner
instead of a generic 500
Full i18n coverage (en + ru) for all new strings.
Rebrand the project as Tinyforge to reflect its evolution from a Docker
container watcher into a self-hosted mini CI/deployment platform.
Rename covers: Go module path, Docker labels, DB/config filenames,
JWT issuer, Dockerfile binary, docker-compose, CI workflows, frontend
i18n, README with static sites docs, and all code comments.
