I know the theory but in practice I wanted a small static server with
Letsencrypt and cron enabled in one small container. So I took a Alpine
base image added s6 and the services needed. BTW Alpine uses busybox
crond not cron. Especially for small an low resource computers you will
prefer 1 containter above 3  separate ones.
