It checks images on a schedule and sends notifications through services such as Gotify, Mail, Slack and Telegram. It can discover images from providers including Docker, Containerd, Kubernetes, Swarm, Nomad, Dockerfile and File, and runs as a single binary or official Docker image under the MIT license.
