Howdy all

I have a playbook that I want to run hourly to check for new hosts and I have a script that returns a variable of new and this host gets the yum update and yum reboot and then come around again this host variable is now old…

My question is how can I get this playbook to run the yum update and reboot when the variable returns as new?

If the variable is old then it skips this
