How to run tasks inside a docker container?

Question

Task Schedulers

Tell me how you can get around Docker's restriction on the work of cron?
You need to run a number of background tasks inside the container
It is said that running the cron daemon directly inside the container is not very recommended
Now I run cron from the host system */25 * * * * docker exec -i -t www /script/cron_job sync
Maybe there are more beautiful options like this do ?

Answer 1

Any application can be in only two states: it either solves the task assigned to it or not. But that's it, a bit of theory.
In your particular case, there is no better option.
If you need to make sure that there is your task in cron on the host machine, then you need chef or ansible
