ARTH - Task 12 👨‍💻

Task Description 📃

Use Ansible playbook to Configure Reverse Proxy i.e. Haproxy and update its configuration file automatically each time a new Managed node (Configured With Apache Webserver) joins the inventory.

Ansible

Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Here I will be using Ansible as a configuration manager.

Load Balancer

Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.

What is HAProxy?

HAProxy is free, open-source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers. It is written in C and has a reputation for being fast and efficient.

What is a Reverse Proxy?

A reverse proxy server is a type of proxy server that typically sits behind the firewall in a private network and directs client requests to the appropriate backend server. A reverse proxy provides an additional level of abstraction and control to ensure the smooth flow of network traffic between clients and servers.

Inventory file:

Configuration file

Check the connectivity:

Now, firstly we have to make some changes in the configuration file of the haproxy such that every time one or more IP connects to our load balancer it will dynamically update in the inventory file without manually doing by us
