Hello,

I wanted to manage repo names from group\_vars based on OS type. I have a requirement to set reponames for different OS & versions like Centos/Redhat/Ubuntu with all stable versions. The goal is to manage future repo names from group\_vars

My variables looks like this

group\_vars/all.yml

</div>

- name: 'Upgrading packages to latest'  
&nbsp;&nbsp;yum:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;name: "\*"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;state: latest  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;enablerepo: "{{ vars[repo\_name] }}"  
&nbsp;&nbsp;when: ansible\_distribution == "RedHat" or ansible\_\_distribution == "CentOS"

or just drop the set\_fact and use

- name: 'Upgrading packages to latest'  
&nbsp;&nbsp;yum:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;name: "\*"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;state: latest  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;enablerepo: "{{ vars['repo\_' ~ ansible\_distribution\_major\_version ~ '\_repo'] }}"  
&nbsp;&nbsp;when: ansible\_distribution == "RedHat" or ansible\_\_distribution == "CentOS"

Thanks Kai! Came across vars & hostvars from FAQ section of ansible. Missed it, thanks for the response.
