I’ve been running a Docker container for a year or so now, the dockerfile doesn’t exist. Now I want the cron.d service to run automatically in this container (
/etc/init.d/cron start). I already found a solution on stackoverflow:
CMD /etc/init.d/cron start
Now the container is already running and I don’t have a dockerfile in which I can use it to rebuild the container. I am confused at this point. How can I use
CMD in a running container? Sure, I can stop it too, but that doesn’t help me because I don’t know how the command should be implemented without a dockerfile.
