Search keyword in “host\_fqdn” variable. If the value has “[lab.com](http://lab.com)” keyword in it, it should directly store the value to “host\_fqdn” again or else it should add “[lab.com](http://lab.com)” keyword to the value and store it to “host\_fqdn” variable. Please assist. vars: host\_fqdn: server host\_fqdn: | {% if ‘[lab.com](http://lab.com)’ in {{ host\_fqdn }} %} {% host\_fqdn = “{{ host\_fqdn }}” %} {% else %} {% host\_fqdn = “{{ host\_fqdn }}.lab.com” %} {% endif %} ---

I'm pretty sure you can't use Jinja in vars like that, but you can have a set\_fact task like this    - set\_fact:        host\_fqdn: "{{ host\_fqdn if 'lab.com' in host\_fqdn else host\_fqdn ~ '.lab.com' }}" ---

Can you please confirm, if the below syntax is correct. I am getting error. vars\_prompt: - name: host\_fqdn prompt: Enter Hostname of a new VM private: no tasks: - set\_fact: host\_fqdn: “{{ host\_fqdn if ‘[lab.com](http://lab.com)’ in host\_fqdn else host\_fqdn ‘.lab.com’ }}” - debug: var=host\_fqdn ---

You are missing the tilde ~ in you syntax, check my previous mail and you'll see the tilde. ---

If possible could you please explain the syntax, It will be very helpful for me to use it in other cases. ---

I could try, not sure if it's understandable Just split it in multiple lines [1] {{ host\_fqdn [2] if 'lab.com' in host\_fqdn [3] else [4] host\_fqdn ~ '.lab.com' }} [2] If the variable host\_fqdn contains the string lab.com the choose [1]. [3] If the variable host\_fqdn dosen't contains the string lab.com the choose [4] [4] Tilde is used to concatenate two strings. So this will concatenate the content of variable fqdn\_host with the string .lab.com You can also use the Ansible ternary filter {{ ('lab.com' in host\_fqdn) | ternary(host\_fqdn, host\_fqdn ~ '.lab.com') }} ---
