Adding a backup crontab into a docker container

Question

I want to implement backup tasks for my docker containers using crontab

Question :

• Is it a nice way to implement backup task of a docker containers ?
• How do you add a crontab ? Dockerfile ?

Answer 1

If you want to run cron as a main purpose of the container than fine, look at some older questions:

• How do I start cron on docker ubuntu base?
• Cron containers for docker - how do they actually work?

If you want to run it as side task (as cron usually run), I would reconsider going with first option :)
