Sure, you can use set\_fact to set it as a task then it will be available for subsequent tasks and when templating.

Here’s how I build up the list of zookeeper hosts to pass to solrcloud. I’m not using private ips but should be adaptable to your situation.

`

- name: set fact zookeeper hosts  
set\_fact:  
zk\_hosts: “{{ groups[‘zookeeper’] | join(':” ~ zookeeper\_client\_port ~ ‘,’) }}:{{ zookeeper\_client\_port }}"  
`

Hope this helps,

Jon
