Welcome to the Ansible documentation guide! This page provides an overview of Ansible, its features, and how to get started.
What is Ansible?
Ansible is an open-source automation tool for IT professionals. It allows you to automate repetitive tasks, such as system configuration, deployment, and management. With Ansible, you can define the desired state of your infrastructure and ensure that it remains in that state automatically.
Features
- Idempotency: Ansible ensures that the desired state is achieved and remains consistent across all systems.
- Agentless: Ansible does not require any software to be installed on the managed nodes.
- Easy to Use: Ansible uses a simple YAML-based syntax for defining tasks and playbooks.
- Extensibility: Ansible has a large ecosystem of modules and plugins for extending its capabilities.
Getting Started
To get started with Ansible, you need to install the Ansible package on your control machine. You can download the package from the Ansible website.
sudo apt-get install ansible
Once Ansible is installed, you can start defining your playbooks. A playbook is a collection of tasks that you want to execute on your managed nodes.
Here's an example playbook that installs Apache on a remote server:
---
- name: Install Apache
hosts: webserver
tasks:
- name: Install Apache
apt:
name: apache2
state: present
To run this playbook, use the following command:
ansible-playbook my_playbook.yml
