Unfortunately, I don’t see any significant differences between your startup logs and mine. On my setup, it ends with: [INFO] DOCKER> [elasticsearch:8.17.3] "elasticsearch": Waited on tcp port '[/172.19.0.2:9200]' 6521 ms Whereas yours ends in a timeout: [ERROR] DOCKER> [elasticsearch:8.17.3] "elasticsearch": Timeout after 60739 ms while waiting on tcp port '[/172.19.0.2:9200]' As for the port binding, the Docker Maven Plugin is configured to bind the container port 9200 to an ephemeral host port, assigning it to the `elasticsearch.port` Maven property: <ports> <!-- Binds an ephemeral port to the `elasticsearch.port` Maven property. --> <port>localhost:elasticsearch.port:9200</port> </ports> This assumes that the Docker host is accessible via `localhost`, which is valid on Linux, but may not hold on macOS. You might want to try omitting the host name altogether: <ports> <!-- Binds an ephemeral port to the `elasticsearch.port` Maven property. --> <port>elasticsearch.port:9200</port> </ports> If that works, please submit a PR to fix the issue in `log4j-layout-template-json` and `log4j-mongodb`.
