Post-Watchtower Docker Container Lifecycle Manager with Safe Updates and Rollback
Watchtower, the most popular Docker container auto-updater, was archived in 2026 after no updates since 2023. The self-hosted community is scrambling for a replacement that handles update detection, safe rollback, and scheduling without silently breaking running services. DIUN notifies but doesn't update; WUD updates but lacks rollback. Dockhand is gaining traction but the space is fragmented.
The killer feature nobody has nailed: automatic Docker volume snapshot before every update, with one-click rollback if health checks fail post-update. That's what makes the difference between 'auto-update tool' and 'container lifecycle manager'. Dockhand is closest but trust is unproven. Ship something stable and boring.

Watchtower's death left a clear vacuum. The replacements each solve one piece: DIUN detects, WUD updates, Tugtainer adds a UI. Nobody has combined detection + approval workflow + automatic pre-update snapshots + rollback + scheduling + multi-host into one tool. This is a consolidation opportunity.
