Describe the enhancement
Describe the problem / motivation
Many log pipelines and docker observation tools work best with JSON in container stdout. Today the image primarily supports customizing PatternLayout via LOG_CONSOLE_FORMAT / LOG_FILE_FORMAT, which still produces unstructured text. (docker-minecraft-server.readthedocs.io)
Proposed enhancement Add an opt-in way to switch console (and optionally file) logs to JSON output using Log4j2’s JsonTemplateLayout. (logging.apache.org)
Suggested UX:
LOG_FORMAT=json(orLOG_LAYOUT=json-template)LOG_JSON_TEMPLATE=<builtin name | path>
