How to run cron inside docker container with php-fpm?

Question

PHP

There is a docker container, php-fpm and a Yii application are spinning in it.
This application has about a dozen Yii commands that are executed via cron.
How to shove cron into this container and make it work?!
Any real experience? Without crutches and prostheses?
All methods from Stackowerflow have already been tried.
PS Why didn't the docker developers provide for human work with cron inside the docker container, is there an official version? :)

Answer 2

The official version is that containers are not virtualization for multiple processes, but isolation of a single process
