My minecraft bot (accompanied by a live chat feed on discord) made for simpvp.net
It is (as of writing) composed of three microservices that communicate using RabbitMQ, using a shared MariaDB database.
In case you want to host your own instance (please don't, or at least not on simpvp), configuration is done through a config.json file in each of the services' working directories.
I'm sure you can figure out what it needs to contain by yourself. It's in the code, anyways.
