Power of Ansible Template: Automate Lika a Pro!

As a system administrator, you are probably bored with updating your configuration files manually on multiple servers. But what if you could automate that process with dynamic reusable files for every system? Let us begin with Ansible template automation, it is the new world of infrastructure as code.

The configuration was created in Ansible, and the Ansible templates module was used to create configuration files. Not only does this diminish the possibility of human error, but it also greatly accelerates the deployment process. When you create Nginx configs, systemd service files, or user environments management with Ansible templates, each configuration file is tailored to the unique properties of the host.

So, let us get into ‘Real World Automation with Ansible Templates’ and take your ‘Configuration Management’ skills to the next level!

What is an Ansible Template?

An Ansible template is a file written in Jinja2 templating syntax that ends in the. j2 extension. These templates give the ability to inject variables and conditional logic in the configuration files directly.

The main tool used is the ansible.builtin.template module, more specifically the template module Ansible offers. This module evaluates Jinja2 templates and copies the resulting files on the remote host.

Syntax:

- name: Render Nginx configuration
  ansible.builtin.template:
    src: templates/nginx.conf.j2
    dest: /etc/nginx/nginx.conf

In this example:

• src is the path to the Jinja2 template on the control machine.
• dest is a destination where a rendered file is to be stored on the managed host.

Template Example: Generate and Deploy Nginx Config with Ansible

Step 1: Create Jinja2 Template (nginx.conf.j2)

server {
  listen 80;
  server_name {{ domain_name }};

  location / {
    proxy_pass http://{{ app_ip }}:{{ app_port }};
  }
}

Step 2: Define Variables

vars:
  domain_name: example.com
  app_ip: 127.0.0.1
  app_port: 3000

Step 3: Template Task Playbook

- name: Deploy Nginx config using template module
  hosts: webservers
  tasks:
    - name: Copy templated nginx config
      ansible.builtin.template:
        src: templates/nginx.conf.j2
        dest: /etc/nginx/sites-available/default

Output:

This will result in the file /etc/nginx/sites-available/default to hold:

server {
  listen 80;
  server_name example.com;

  location / {
    proxy_pass http://127.0.0.1:3000;
  }
}

Advanced Template Features

Conditional Logic

{% if enable_ssl %}
  listen 443 ssl;
{% else %}
  listen 80;
{% endif %}

Loops

{% for user in users %}
  - {{ user.name }} ({{ user.email }})
{% endfor %}

Filters

The current date is {{ ansible_date_time.date | replace('-', '/') }}

Overall, these features make Ansible templates very flexible and powerful in any automation scenario.
