What is Ansible?

Ansible is a powerful and flexible automation platform that allows you to automate configuration management, application deployment, and orchestration of tasks across your IT infrastructure. It uses a simple and easy-to-understand language called YAML (Yet Another Markup Language) for defining automation tasks, making it accessible to both beginners and experienced system administrators.

Why Use Ansible IT Automation?

Ansible offers several benefits that make it a popular choice for IT automation:

  • Simplicity: Ansible has a shallow learning curve, making it easy to get started with automation even for those without extensive programming knowledge.
  • Agentless Architecture: Ansible operates over SSH, which means you don’t need to install any agents or additional software on the managed hosts. This reduces complexity and makes it easier to manage a large number of servers.
  • Idempotency: Ansible ensures that the desired state of the system is achieved regardless of the initial state. This means you can safely run the same playbook multiple times without causing any unintended consequences.
  • Community and Ecosystem: Ansible has a vibrant and active community, with a vast collection of pre-built roles and modules available for various use cases. This allows you to leverage existing solutions and easily share your automation code with others.


Before we proceed with the installation, make sure you have the following prerequisites in place:

  • An Ubuntu 22.04 server with a user account with sudo privileges.
  • Access to the internet to download and install Ansible.

Now that we have the prerequisites sorted, let’s move on to the installation process.

Installing Ansible on Ubuntu 22.04

To install Ansible on Ubuntu 22.04, follow these steps:

  1. Open a terminal on your Ubuntu server.
  2. Update the package lists for upgrades and new package installations:
   sudo apt update
  1. Install Ansible by running the following command:
   sudo apt install ansible
  1. Confirm the installation by checking the Ansible version:
   ansible --version

This will display the installed Ansible version, indicating a successful installation.

Congratulations! You have successfully installed Ansible IT Automation on Ubuntu 22.04.

Configuring Ansible

After installing Ansible, you need to configure it to work with your infrastructure. Ansible uses a configuration file located at /etc/ansible/ansible.cfg. You can modify this file to suit your needs, but the default configuration should work fine for most scenarios.

To configure Ansible, open the configuration file using a text editor:

sudo nano /etc/ansible/ansible.cfg

Here are a few

configuration options you might want to consider:

  • Inventory: The inventory file defines the hosts and groups that Ansible can manage. By default, the inventory file is located at /etc/ansible/hosts.
  • Remote User: Ansible connects to managed hosts using SSH. You can specify the remote user in the configuration file using the remote_user option.
  • Privilege Escalation: If you need to execute commands with elevated privileges (e.g., using sudo), you can enable privilege escalation by uncommenting the relevant lines in the configuration file.

Make the necessary changes to the configuration file and save it. Ansible is now ready to be used with your infrastructure.

How to Write Ansible Playbooks

Ansible Playbooks are written in YAML and allow you to define a set of tasks that should be executed on remote hosts. Playbooks provide a way to automate complex multi-step processes.

To create an Ansible playbook, follow these steps:

  1. Create a new YAML file using a text editor:
   nano playbook.yaml
  1. Define the playbook structure and add tasks using YAML syntax. For example, to install a package, you can use the apt module:
   - name: Install nginx
     hosts: webserver
       - name: Install nginx package
           name: nginx
           state: present
  1. Save the playbook file.
  2. Run the playbook using the ansible-playbook command:
   ansible-playbook playbook.yaml

Ansible will connect to the specified hosts and execute the tasks defined in the playbook.

Ansible Modules

Ansible provides a rich collection of modules that you can use to perform various tasks. Modules are self-contained units of code that can be executed by Ansible. They can be used to manage packages, files, services, users, and much more.

To discover available modules and their documentation, visit the official Ansible documentation website at https://docs.ansible.com/. You can also use the ansible-doc command to view the documentation directly from the command line.

Ansible Roles

Roles are a way to organize and structure your Ansible code. They allow you to reuse and share common sets of tasks, handlers, and variables across multiple playbooks.

To create an Ansible role, follow these steps:

  1. Create a new role using the ansible-galaxy command:
   ansible-galaxy init role_name

This will create a new directory structure for your role with predefined directories for tasks, handlers, variables, and more.

  1. Add the necessary tasks, handlers, and variables to the role directories.
  2. Use the role in your playbook by including it in the roles section:
   - name: Example playbook
     hosts: webserver
       - role_name

Ansible will automatically execute the tasks defined in the role when the playbook runs.

Troubleshooting Ansible

While Ansible is generally straightforward to use, you may encounter issues during installation or execution. Here are a few common troubleshooting steps:

  1. Ensure that Ansible is correctly installed and that you are using the latest version.
  2. Double-check your configuration files, including the inventory and playbook syntax.
  3. Verify that SSH connectivity is working correctly between the Ansible control node and the managed hosts.
  4. Check the Ansible documentation and community forums for known issues and solutions.

If you’re still experiencing problems, don’t hesitate to ask for help from the Ansible community or seek assistance from experienced Ansible users.
