Today we are going to discuss how to use Ansible to configure HaProxy LoadBalancer using the concept of Dynamic Inventory. For this, we are using AWS as a cloud provider.
The overall scenario would be as follows:
Deploy a Load Balancer and multiple Web Servers on AWS instances through ANSIBLE!
🔅Provision EC2 instances through ansible.
🔅 Retrieve the IP Address of instances using the dynamic inventory concept.
🔅Configure the web servers through the ansible role.
🔅Configure the load balancer through the ansible role.
🔅The target nodes of the load balancer should auto-update as per the status of web…
Today we are going to discuss ansible dynamic inventory. The Ansible inventory file describes the hosts and groups of hosts upon which commands, modules, and tasks in a playbook operate. The inventory file contains to list of IP and hostname where you want to perform certain tasks.

Today we are going to integrate the two most popular DevOps tools. Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. Automation is crucial these days, with IT environments that are too complex and often need to scale too quickly for system administrators and developers to keep up if they had to do everything manually. Automation simplifies complex tasks, not just making developers’ jobs more manageable but allowing them to focus attention on other tasks that add value to an organization. In other words, it frees…
Amazon EC2( Elastic Compute Cloud ) is an infrastructure cloud computing service that provides scalable computing capacity in the cloud and eliminates your need to invest in hardware upfront, So you can develop and deploy applications faster.
Now that we know what is EC2 in AWS, Now we look forward and understand why we need EC2 and what are the benefits of using Amazon EC2.
