'How can I set the crond for docker? [duplicate]

I installed cron and

FROM python:3.9.5
ENV PYTHONUNBUFFERED 1

RUN apt-get update && apt-get install -y netcat && apt-get install -y ftp && apt-get install -y cron

log in the docker image

root@ip-172-31-12-132:/usr/src/app# which ftp
/usr/bin/ftp


root@ip-172-31-12-132:/usr/src/app# ps -aef | grep cron
root      1386   764  0 02:15 pts/1    00:00:00 grep cron

no cron is running

root@ip-172-31-12-132:/usr/src/app# crontab -l
no crontab for root

I guess I have to do something to start cron server.

root@ip-172-31-12-132:/usr/src/app# service crond start
crond: unrecognized service

root@ip-172-31-12-132:/usr/src/app# /etc/init.d/crond start
bash: /etc/init.d/crond: No such file or directory

How can I do this??
