lmenezes/cerebro ? reverse-engineered prompt

Build me a simple browser based admin tool for Elasticsearch that I can open locally and use to connect to a cluster, inspect what is going on, and handle basic admin tasks from a friendly web UI. I want it to run on Java 11 or newer, start up easily on localhost on port 9000 by default, and let me change the host, port, or point it at a different config file when needed.

Please make it easy to run both as a normal app and in Docker. Add optional LDAP login through environment variables so teams can lock it down without much setup. Keep the interface clean and practical, the kind of tool an ops person could use quickly without digging through docs.

Use the existing examples and config approach where it makes sense, and make sure the main settings are obvious. If anything is unclear, look up current docs online and fill in the gaps with sensible defaults.
