Some time ago I created a playbook to show the content of a rendered
template. When you keep digging in the Ansible documentation, you
suddenly stumble over the template lookup-plugin. And then it turns
out that my playbook is a bit clumsy.
A nicer and shorter way to do it:
---
#
# This playbook renders a template and shows the results
# Run this playbook with:
#
# ansible-playbook -e templ=<name of the template> template_test.yml
#
- hosts: localhost
become: false
connection: local
tasks:
- fail:
msg: "Bailing out. The play requires a template name (templ=...)"
when: templ is undefined
- name: show templating results
debug:
msg: "{{ lookup('template', templ) }}"
