Manual execution?

Hi, I just deployed a docker container (and i'm pretty new to docker). I added; --restart unless-stopped \ to start the container when the host is rebooted for some reason, so I don't forget to start the container. I wanted to test the snapshot execution so I don't have to wait until 1 am following the crontab so I ran; docker exec -it 7f6772ed0a6d python3 snapshot-as-backup.py this gave me as output; Starting CronScheduler [0 1 * * *]... I've waited about 15min but I don't see any snapshots being made. Is it possible somehow? Thanks!
