Step-by-Step Explanation

1. Read
Ansible reads the employee.j2 template file and detects the custom placeholder syntax items written inside double curly braces {{ }}.
2. Parse
It matches those template keys against the variable data models defined securely in the vars: section of the playbook.
3. Replace
The native template module automatically substitutes every placeholder variable with its actual corresponding real-time runtime value.
4. Create
The completed, fully flattened destination text file is securely provisioned on the host at /tmp/employee.txt.
