Introduction: As businesses strive for agility and scalability, the demand for rapid infrastructure provisioning has grown exponentially. Ansible, a powerful configuration management and automation tool, allows you to provision infrastructure as code, enabling you to create, configure, and manage resources programmatically. In this blog, we will explore how Ansible can be utilized to provision infrastructure as code, making the process efficient, consistent, and easily reproducible.

Installing Ansible:

firstly, Before diving into infrastructure provisioning, ensure you have Ansible installed on your system. Ansible supports various operating systems, and installation instructions can be found on the official Ansible website (

Creating the Inventory:

Secondly, The first step in provisioning infrastructure with Ansible is defining the inventory, which contains a list of target hosts and their connection details. You can organize hosts into groups based on their roles or environments.

Example inventory.yaml:



Writing the Playbook:

A playbook is a YAML file that defines a set of tasks to be executed on specific hosts in the inventory. It includes roles, tasks, and optional variables to customize the configuration.

Example playbook.yaml:

Creating Templates:

Ansible allows you to use Jinja2 templates to generate dynamic configuration files. These templates can include variables and conditional logic, enabling you to customize configurations based on specific host attributes.

Example nginx_config.j2:

user www-data;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/;

events {
worker_connections 1024;

http {
server {
listen 80;
server_name {{ ansible_hostname }};

    location / {
        proxy_pass http://backend_servers;


Running the Playbook:

To provision infrastructure as code, execute the Ansible playbook with the inventory file and any required variables.

ansible-playbook -i inventory.yaml playbook.yaml


Finally, Provisioning infrastructure as code with Ansible empowers organizations to automate the setup and configuration of resources swiftly and consistently. By creating an inventory, writing playbooks, utilizing Jinja2 templates, and running the provisioning process as code, you can ensure that your infrastructure is easily reproducible, maintainable, and scalable.

Lastly, Remember to adapt these Ansible code snippets to match your specific infrastructure requirements, and explore additional Ansible modules and plugins to further enhance your infrastructure provisioning capabilities.

Happy provisioning with Ansible!
