Another update notifier for Docker — but with proxies and no auto-updates

▤ Summary

The article introduces Versentry, a Docker update notification tool that monitors container image changes and sends alerts through channels like Telegram, Discord, Gotify, ntfy, and webhooks. It positions itself as an alternative to tools such as Watchtower, Diun, and WUD by focusing on notification workflows rather than automatic updates. The article explains support for proxies, digest tracking, regex-based matching, Docker Hub and other registries, and deployment across Docker, K8s, Swarm, and Podman. It also includes a sample compose configuration and shows how users can configure rules, credentials, and notification settings.
