About dockcheck
dockcheck is a shell script that looks for newer images for your running Docker containers and either tells you about them or updates the containers. It can run interactively, letting you pick which containers to update, or unattended on a schedule.
Options include selective updates, including or excluding specific containers, backing up the old image before updating, pruning old images automatically and sending notifications through a set of templates. It checks for updates without pulling the images first. It suits people running a home server or small Docker host who want updates under their own control.
