I am trying to build a docker image which would have a cron. A cron which will delete files from particular location of docker file system. Below is my Dockerfile
FROM ubuntu:latest MAINTAINER [email protected] RUN apt-get update && apt-get -y install cron # Copy testfiles folder to docker container. COPY ./testfiles /opt/ # Create the log file to be able to run tail RUN touch /var/log/cron.log RUN (crontab -l -u root; echo "* * * * * root rm -rf /opt/*") | crontab # Run the command on container startup CMD cron ENTRYPOINT ["/bin/sh", "-c", "/bin/bash"]
Everything is successful. my cron is also set in the container
roadrunner:test shailesh$ docker run -it crontest /bin/bash root@ac31f5acc49f:/# ls bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var root@ac31f5acc49f:/# crontab -l * * * * * root rm -rf /opt/* root@ac31f5acc49f:/# cd /opt/ root@ac31f5acc49f:/opt# ls file1 file10 file11 file12 file13 file14 file15 file16 file17 file18 file19 file2 file20 file21 file22 file23 file24 file25 file3 file4 file5 file6 file7 file8 file9
However it is not running and deleting the files which are in
/opt/ folder. Can someone tell me what is wrong in the configuration.
