kestra-io/kestra ? reverse-engineered prompt

I want you to build a platform for automating our workflows. It should have a clean web UI where we can visually build out processes, monitor their execution, and see the results. The core of the system should be defining these workflows as code, using a simple YAML configuration. The UI should have a nice built-in editor for this, with autocompletion.

The platform needs to support two main types of automation: tasks that run on a schedule, like a nightly data job, and tasks that are triggered by events, like processing a file when it's uploaded. It should be highly scalable and come with a plugin system to easily connect to databases, cloud storage, and other APIs. The backend will be Java, but it's crucial that our workflows can run scripts written in Python, Node, or even just shell commands. Please set it up to run locally using Docker.
