Have used compose file from documentation: public/docker/swarm.docker-compose.yaml at master · datagrok-ai/public · GitHub
Can anyone point me to right direction?

Reason - lack of ENV variable GROK_PARAMETERS

Hi @eyewing. Yes, the swarm.docker-compose.yaml is a little bit outdated and we have plans to deprecate it completely. But I have added necessary env variable. Could you please use updated version of public/docker/swarm.docker-compose.yaml at master · datagrok-ai/public · GitHub and follow this guide Docker Swarm | Datagrok?

Yep, already fixed exactly as you, thank you for the reaction! I need to close the thread?
