Two tier Design Using Local Variables

Updated Dec 16, 2020 ·

Overview

This lab uses local playbook variables to keep repeated values close to the tasks that need them.

Diagram:

Here we're using vars in our playbook just like in any programming language where variables are defined at the beginning.

setup-app-localvars.yml

# setup-app-localvars.yml
# Similar with setup-app-var.yml, but here we're using local variables

- name: Copy app file onto webservers 
  become: true
  vars:
    path_to_app: "/var/www/html"
  hosts: webservers
  tasks:

    - name: Upload application file
      copy:
        src: ~/proj-ansible-1/one/files/index.php
        dest: "{{ path_to_app }}"
        mode: 0755

    - name: Create simple info page
      copy:
        dest: "{{ path_to_app }}/info.php"
        content: "<h1> Info about our webserver: {{ ansible_hostname }} </h1>"
