Hello,

I have a question, I want 2 use a URL that has to be dynamically generated. I will be providing the version as a variable to the URL. So here’s what I am doing.

1. I have the url variable defined in defaults/main.yml like this  
url: [https://some.app.here/version-](https://some.app.here/version-){{ version\_no }}.tar.gz

2. I have the variable version\_no defined in the vars/main.yml file as below.  
version\_no:1.2.3

So now my question is, will this work? Will the value of url variable will be [https://some.app.here/version-1.2.3.tar.gz](https://some.app.here/version-1.2.3.tar.gz) after evaluation?

Please let me know if this is possible? If not, please suggest me some solution to achieve the same.
