Docker Updater puts you back in charge of container updates: it watches your registries for newer images, and nothing updates until you approve it, so no database restarts itself at dinner. Polls run on a schedule you set, and each container card shows the newer image waiting before anything is pulled. The check costs nothing: it compares the digest your container runs against the registry manifest without pulling a byte, across Docker Hub, GHCR and other Bearer-token registries. Read the last five GitHub releases for an image before committing, update one container or a batch, and watch the pull percentage, layer count and recreation step stream live on the card. If the new container fails to start, the old one returns automatically, and you can keep a backup even after a clean update. Not ready? Defer an update for 7, 14, 30 or 90 days, or indefinitely, and it leaves your notifications alone until then. Several Docker hosts join the same dashboard over SSH or TCP with health indicators, and Compose stacks restart together so services find new addresses. Notifications arrive through an auto-generated ntfy topic or your own Apprise URL, every update keeps a persistent log, and a reclaimable-images view shows what disk space old images hold. The dashboard serves on port 9090 in English or Simplified Chinese, with optional login.
