Ansible Template Module Create Directory Made Easy

Quick Links :

Creating directories is a common task in IT automation, and Ansible's template module can make this process easier and more efficient. Ansible is an open-source automation tool that allows you to automate repetitive tasks, such as creating directories, copying files, and configuring systems. In this article, we will explore how to use Ansible's template module to create directories and make your IT automation tasks more manageable.

Why Use Ansible's Template Module?

Ansible's template module is a powerful tool that allows you to create directories and files based on templates. This module uses the Jinja2 templating engine to replace placeholders in a template file with actual values. The template module is useful when you need to create multiple directories with similar structures or files with similar content. By using templates, you can define the structure and content of the directories and files once and then use Ansible to create them with different values.

How to Use Ansible's Template Module to Create Directories

To use Ansible's template module to create directories, you need to follow these steps:

1. Create a template file that defines the structure of the directory.
2. Define the values that will replace the placeholders in the template file.
3. Use the template module in your Ansible playbook to create the directory.

Step 1: Create a Template File

Create a file called directory_template.j2 with the following content:

{% for dir in directories %}
{{ dir.name }}/
{% endfor %}

This template file uses a loop to create multiple directories. The directories variable is a list of dictionaries that contains the name of each directory.

Step 2: Define the Values

In your Ansible playbook, define the directories variable as follows:

---
- name: Create directories
  hosts: localhost
  vars:
    directories:
      - name: dir1
      - name: dir2
      - name: dir3

This variable defines a list of three directories with names dir1, dir2, and dir3.

Step 3: Use the Template Module

Use the template module in your Ansible playbook to create the directories:

---
- name: Create directories
  hosts: localhost
  vars:
    directories:
      - name: dir1
      - name: dir2
      - name: dir3
  tasks:
  - name: Create directories
    template:
      src: directory_template.j2
      dest: /tmp/directories
      mode: '0755'

This playbook uses the template module to create the directories in the /tmp/directories path. The src parameter specifies the template file, and the dest parameter specifies the destination path. The mode parameter sets the permissions of the created directories.
