This is an Ansible playbook that can upgrade all your Linux machines! Or at least most of them. No openSUSE support yet.

Copy the playbook below, and put all your servers into an inventory file and run with

ansible-playbook -i hosts.ini master_update.yaml --ask-vault-pass

Couple of notes.

1. This will do a full update automatically reboot your servers if needed.
2. There is a special section for RHEL, CentOS 7 servers. If a server is running say CentOS 7, it will default to using YUM instead of DNF.
3. You need sudo or become: yes to reboot and install upgrades.
