yum-cron equivalent in amazon linux 2

Question

It looks like yum-cron is unavailable in amazon linux 2.X, how can I enable automatic updates?

I'm trying to install both security and non-security updates automatically.

Answer 1

You can simulate this util by executing in cron something like:

0 0 * * 6 yum upgrade -y

This will exec update via yum at midnight every Saturday. You can of course tune the schedule per your requirements.
In cron you can add MAILTO to send mail to someone withe the result of update.

If you want to fully automate the process you can use needs-restarting to check if the system need restart and do it.
