what is tomcat fr?

This repository provides a Docker image that runs Apache Tomcat (a web server) and adds a simple webhook receiver on top of it. Think of it as a lightweight notification system: when you push an updated Docker image to Docker Hub, this setup can receive a notification message about it, letting you know that something has changed. The core idea is practical but modest. Docker Hub can send automatic notifications (called webhooks) when you build or update a container image. This project gives you a straightforward way to receive and listen for those notifications using Tomcat as the underlying server. Rather than setting up a complex event management system, you get a "poor man's" solution, something simple and free that does the job without extra overhead. At a high level, you'd use this by setting up a Docker container from this image, exposing it to the internet, and then telling Docker Hub to send notifications to its webhook endpoint. When you push a new version of your app or container to Docker Hub, the notification arrives at this running instance, and you can act on it, maybe trigger a deployment, log the event, or alert your team. This approach appeals to smaller teams or solo developers who need basic automation without the complexity and cost of enterprise-grade deployment systems. If you're using Docker Hub to host your images and want a lightweight way to know when builds complete or when updates happen, this gives you that visibility without much infrastructure overhead. It's the kind of quick solution someone might set up for a side project or early-stage startup where simplicity and low cost matter more than industrial-strength monitoring.
