How to Install Ansible

Install Ansible for Configuration Automation

Ansible is a powerful open-source automation tool that helps you automate IT infrastructure and application deployment. It is written in Python and is agentless, meaning it doesn't require any software to be installed on the machines you want to manage. Ansible uses a simple YAML-based language to define the desired state of your systems, and then it automatically takes the necessary steps to achieve that state.

Ansible requires a Control Node that connects with the managed hosts thought ssh to make the desired changes. Installation is done in the Control Node and this node installs the needed packages in the managed hosts when needed.

How to install Ansible on Ubuntu

  1. Install Ansible on the Control Node

    Install Ansible using apt.

  2. Check Ansible Installation

    Check that Ansible has been installed.

  3. Next Steps

    Use Ansible with Terraform for configuration management.

$ sudo apt-add-repository ppa:ansible/ansible
