Ansible Has a Free IT Automation Platform

Ansible is a free, open-source IT automation tool that automates server configuration, application deployment, and orchestration — all without agents.

What Is Ansible?

Ansible uses SSH to connect to servers and execute tasks defined in YAML files called playbooks. No agents to install. No database. Just SSH.

Key features:

• Agentless (uses SSH)
• YAML-based playbooks
• 3,000+ modules (packages, files, services, cloud, etc.)
• Idempotent (safe to run multiple times)
• Inventory management
• Roles and Galaxy (reusable components)
• Vault (encrypted secrets)
• Free and open source

Quick Start

pip install ansible

Example Playbook

# deploy.yml
- hosts: webservers
  become: yes
  tasks:
    - name: Install Nginx
      apt:
        name: nginx
        state: present

    - name: Copy site config
      template:
        src: nginx.conf.j2
        dest: /etc/nginx/sites-available/default
      notify: Restart Nginx

    - name: Deploy app
      git:
        repo: https://github.com/myorg/myapp.git
        dest: /var/www/myapp
        version: main

  handlers:
    - name: Restart Nginx
      service:
        name: nginx
        state: restarted

ansible-playbook -i inventory.ini deploy.yml
