cron - cronjob not executed on docker swarm deployment -

-

i using docker swarm control deployment several containers used machine learning application.

i have bash script sends commands executed containers. when execute script manually in console, works fine, commands sent containers , run when added same script executed cron, doesn't work (i using crontab -e command script executed user)

here's 1 example of scripts need run:

eval $(docker-machine env --swarm director) docker exec -d container_luigi-worker_1 luigi  --module etl alltasks

and cron line is: 16 * * * * sh /path/script.sh

as using swarm, first need env of director, execute command using docker exec (in case command start job using spotify's luigi tool)

what missing? thanks
