Hi,
example from previous reply will do all stages for you:
- name: Ensure packages are installed and the latest available version
yum: name="{{ item }}" state=latest
with_items:
- some_package
- some_other_package
- a_third_package
This will check package presence, then install it if it is not installed
and update if it is. This is the key: "state=latest"
