Container Image Cleanup

This tool regularly removes all unused container images from your computer. It sets up a scheduled task (cron job) depending on whether you have Podman or Docker installed.

Requirements

Before setting up the scheduled task, it checks if either Podman or Docker is installed on your system.

Role Variables

There are settings in the defaults/main.yml file to control when the scheduled task runs and to specify where to find Docker and Podman.
