Add an optional periodic auto-update daemon that detects outdated container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for Outdated: standalone -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.
