Using host groups in a playbook

[István Szukács]

Hi everybody,

I was wondering what is the most idiomatic way of doing the following:

---

- name: Install

  hosts: 'webservers'

  remote_user: 'centos'

  roles:

    - { role: 'webserver', db_conn_string: 'hostA.tld.com:9999,hostB.tld.com:9999,hostC.tld.com:9999' }

The db hosts are are called [database] group in the hosts file.

Can I generate the db conn string somehow in the playbook or there is better way of achieving this.

Thank you in advance,

Istvan

try 

{{ ":9999,".join(groups['database']) + ':9999' }}
