Add an optional periodic auto-update daemon that detects outdated container
images and applies updates, replacing the containrrr/watchtower sidecar. It
extends M1's containerautomation service/scheduler/labels infrastructure and
reuses the existing zlib image-detection engine, the standalone Recreate path
and the stack deployer.
Backend:
- api/containerautomation/autoupdate.go: scheduler job iterating Docker
(non-edge) endpoints -> in-scope running containers -> ContainerImageStatus;
for Outdated: standalone -> ContainerService.Recreate(pull); stack-managed ->
one stack redeploy-with-pull per stack per tick (git via RedeployWhenChanged,
file via the deployer directly); external compose -> detect only. Monitor-only
containers are status-checked (warms the badge cache) but never applied.
Overlap guard (atomic), pull/registry-auth failure -> leave running container
untouched, conservative cleanup of the dangling old image on the Cleanup flag
(non-forced ImageRemove only succeeds when truly unused).
- labels.go: update enable / monitor-only labels with watchtower aliases,
InUpdateScope, IsMonitorOnly, and pure resolveContainerUpdateRouting /
groupContainersForUpdate (Go analogue of M3's TS routing + grouping).
- service.go: run both jobs, Reload restarts/stops each per settings; NewService
also takes ContainerService, StackDeployer and GitService.
- Settings.ContainerAutomation.AutoUpdate {Enabled, PollInterval, Scope,
Cleanup} with fresh-install defaults and a 2.43.0 backfill (extends M1's
migration; golden test data updated). settings handler validates + reloads.
Frontend:
- Global AutoUpdatePanel in SettingsView (enable / poll interval / scope /
cleanup) via useUpdateSettingsMutation, plus settings TS types.
- Read-only per-container Auto-update row in the container details view
(Docker labels are immutable at runtime), surfacing monitor-only.
Tests: Go unit tests for the update label aliases, scope, monitor-only, the
routing decision and the one-redeploy-per-stack grouping; vitest for the panel
and the per-container row.

F1: prune retry-state by elapsed window since lastRestart instead of "not
seen this tick", so a container flapping through "starting" keeps its
cooldown/max-retries accounting (storm guard no longer defeated). Recovered
containers quiet for > window are still cleaned up.
F2: list running containers only (All:false) so stopped-unhealthy containers
are never revived.
F3: each ContainerRestart gets its own context (stop-timeout + buffer),
separate from the per-endpoint list context, so a slow/hung restart cannot
starve the others or exhaust a single shared deadline.
F4: start() is idempotent (no-op when a job is already scheduled); Reload
still stops first so it always reschedules.
F5: frontend parseBool mirrors Go strconv.ParseBool (case-insensitive
1/t/true; present-but-invalid counts as present & false).
F6: tests TestPruneRetries and TestRetryStateSurvivesStartingTick lock in
the F1 behavior; added AutoHealRow parse cases.

Add a native, CE-only auto-heal daemon that restarts Docker containers whose
healthcheck reports "unhealthy", replacing the willfarrell/autoheal sidecar.
Backend:
- New package api/containerautomation (service lifecycle + scheduler job,
per-endpoint heal pass, label/scope parsing, in-memory cooldown/retry state).
- Settings.ContainerAutomation.AutoHeal {Enabled, CheckInterval, Scope} with
fresh-install defaults and a 2.43.0 migration backfilling existing installs.
- Settings update handler reloads/stops the job via a small Reloader interface
(no import cycle); service bootstrapped from main.go after stack schedules.
Frontend:
- Global AutoHealPanel in SettingsView (enable / interval / scope) via
useUpdateSettingsMutation, plus settings TS types.
- Read-only per-container Auto-heal row in the container details view (Docker
labels are immutable at runtime; opt-in is set via Create/Edit form labels).
Tests: Go unit tests for label/scope resolution and the cooldown/retry decision;
vitest for the panel and the per-container row.
