When should I use {{ }}? Also, how to interpolate variables or dynamic variable names
Answer Posted / Pushpendra Singh Thakur
In Ansible, double curly braces `{{ }}` are used for variable interpolation. This means that Ansible replaces the double curly braces with the value of the specified variable at runtime. For example, if you have a variable named `host`, you can use it in your playbook like this: `hosts: {{ host_list }}`. To interpolate dynamic variable names, you can use the `set_fact` or ` vars ` keywords to define a new variable dynamically during the playbook execution.
