Issues running cron in Docker on different hosts

Question

Im trying to get a docker container running to mange my cronjobs

im running a very simple cron as a test in a docker container using centOS 6.5 base

Answer 1

the base Docker containers don't start services like cron - they only start what you specify in the ENTRYPOINT/CMD

some 'fatter' containers use things like supervisord to start services - but where possible, its more maintainable to separate services into different containers and share data using with volume containers, or --link
