When starting docker compose image from open-core/docker-compose.yml, it runs graylog-datanode:5.2, which is not starting correctly due to error:

Hi, @djaparidze please configure docker/your OS to use the correct setting as written here: https://go2docs.graylog.org/5-2/setting_up_graylog/graylog_data_node_getting_started.htm?tocpath=Setting%20up%20Graylog%7CGraylog%20Data%20Node%7C_____1

You'll probably want to start over after doing that by issuing docker compose down -v

Please let me know if it works for you!

Worked for me, thanks!

the OP did not come back to this issue but I guess it's fixed now because the solution works for other users.
