Override Ansible facts similar to Puppet and Facter override

Question

NOTE: Part of Puppet to Ansible migration evaluation. Ansible noob.

CentOS 7 returns operatingsystemrelease (puppet) or ansible_distribution_version (ansible) as 7.2.1511 instead of just 7.2. So in puppet we use the following hack.

# Hack for CentOS 7. operatingsystemrelease includes third part of release version eg 7.2.1511
if [[ "$(facter operatingsystem)" == "CentOS" && "$(facter operatingsystemmajrelease)" == "7" ]]
then
    export FACTER_operatingsystemrelease=$(facter operatingsystemmajrelease).$(facter --json os | grep minor | awk '{ print $2 }' | tr '",' ' ' | sed -e 's/ //g')
fi

Setting environment variable FACTER_operatingsystemrelease overrides the operatingsystemrelease value. This needs to happen only for CentOS 7. CentOS 6 works fine.

What would be the equivalent way to make this work in Ansible?

You can override facts as any other variable:

set_fact: ansible_distribution_version="{{ ansible_distribution_version | regex_replace('7\.2\.\d+','7.2') }}"
when: ansible_distribution == 'CentOS'

This needs to be done in playbook under -tasks or hosts? Sorry still learning. – MavWolverine Sep 15 '16 at 18:26
As I test, I tried running "ansible -m setup -i hosts -u centos -c local --extra-vars "ansible_distribution_version=7.2" localhost", But it still was 7.2.1511. – MavWolverine Sep 15 '16 at 18:29
Also, is there any way to overwrite any other variable only for one command or one run? – MavWolverine Sep 15 '16 at 18:30
