Introduction:

Ansible is an open-source automation tool that allows you to automate a wide variety of IT tasks, such as configuration management, application deployment, and infrastructure provisioning. It’s designed to help systems administrators and developers streamline the process of managing servers and applications, making it easier to scale infrastructure and manage complex environments.

Key Features & Concepts:

1. Infrastructure as Code (IaC): With Ansible, you can define and provide data center infrastructure using a declarative configuration language. This means you describe your desired state, and Ansible makes it so.

2. Playbooks: Ansible tasks are written in YAML format and are referred to as playbooks. Playbooks are scripts that define the tasks and the order in which they run.

3. Modules: Ansible uses modules to manage different resources. There are core modules for managing files, databases, cloud resources, networking devices, and more.

4. Idempotence: One of the core principles of Ansible. It ensures that operations produce the same results whether they’re applied once or multiple times.

5. Agentless: Unlike some other configuration management tools, Ansible does not require an agent to be installed on the client system. It typically communicates over SSH (or WinRM for Windows).

6. Inventory: Ansible uses an inventory to track and manage which hosts it communicates with.

7. Roles: To simplify playbook distribution and execution, Ansible has a ‘roles’ system. Roles allow you to bundle automation content and make it reusable.

8. Ansible Galaxy: A community hub where users can share Ansible roles and collections.

9. Ansible Tower: A web-based solution that makes Ansible even more easy to use for IT teams of all kinds. It’s particularly useful for role-based access control, scheduling, and centralized logging.

Benefits:
  • Simplicity: The straightforward YAML syntax is easy to learn, read, and write.
  • Consistency: Ensure all your systems are set up the same way, every time.
  • Reliability: If something goes wrong, you can use Ansible to bring your system back to a known good state.
  • Efficiency: Automation means doing more with fewer errors in less time.
  • Scalability: Ansible can manage one machine just as easily as it can manage 1,000 or more.

How Ansible Works:

Ansible works by connecting to your nodes and pushing out small programs, called “Ansible modules”, to them. These programs are written to be resource models of the desired state of the system. Ansible then executes these modules (over SSH by default), and removes them when finished. Your library of modules can reside on any machine, and there are no servers, daemons, or databases required. Typically you’ll work with your favourite terminal program, a text editor, and probably a version control system to keep track of changes to your content. In summary, Ansible provides a powerful and flexible toolset for automating a wide range of IT tasks, from configuration management to application deployment. Its simplicity and agentless architecture have led to its rapid adoption in the DevOps community and beyond.

Prerequisites:

1. Ubuntu System: A running instance of Ubuntu 22.04. It can be a virtual machine or a physical server.

2. SSH Access: Ensure you have SSH access to your Ubuntu instance. Ansible uses SSH to communicate with target machines.

3. User with sudo Privileges: The user account should have sudo privileges to install software packages.

Steps to Install Ansible in Ubuntu 22.04:

Here’s a general step-by-step guide for installing Ansible on Ubuntu, which you can adapt for Ubuntu 22.04:

1. Update System:

    First, make sure your system package repositories are up to date:

  ubuntu@rushi-infotech:~$ sudo apt update
  ubuntu@rushi-infotech:~$ sudo apt upgrade -y

Click on “Enter

Click on “Enter

2. Install Software Properties Utility:

    This utility allows you to manage distribution and independent software vendor software sources:

  ubuntu@rushi-infotech:~$ sudo apt install software-properties-common

3. Add Ansible’s PPA (Personal Package Archive):

    Ansible provides an official PPA that holds the latest stable versions:

  ubuntu@rushi-infotech:~$ sudo add-apt-repository ppa:ansible/ansible

Click on “Enter

4. Install Ansible:

    Now, update your package index again and then install Ansible:

  ubuntu@rushi-infotech:~$ sudo apt update
  ubuntu@rushi-infotech:~$ sudo apt install ansible -y
  Click on "Enter"
  Click on "Enter"

Ansible has Successfully Installed.

5. Verify Ansible Installation:

You can check the version of Ansible to ensure it has been installed correctly:

  ubuntu@rushi-infotech:~$ ansible –-version

This will display details about the Ansible version and its configuration.

6. Optional: Ansible Configuration:    

Ansible uses a configuration file, typically which you can modify to fit your specific needs.

ubuntu@rushi-infotech:~$ sudo vi /etc/ansible/ansible.cfg 

    Additionally, Ansible works based on inventory files where you list the hosts you wish to manage. By default, the inventory file is found at

ubuntu@rushi-infotech:~$ sudo vi /etc/ansibl1e/hosts2

That’s the basic process to get Ansible installed on Ubuntu. Once Ubuntu 22.04 is officially released, always refer to the official Ansible documentation or any specific guidance provided by the Ubuntu community, especially if there are version-specific nuances or updates.
