Introduction

Why Ansible is important for DevOps

Ansible is used to automate configuration, deployment, orchestration, and other infrastructure operations. Its automation model uses concepts such as inventories, playbooks, modules, and managed nodes.

Playbooks are written in YAML and allow teams to define repeatable automation tasks that can be executed across multiple systems.

This makes Ansible useful for configuration management, application deployment, infrastructure automation, and DevOps workflows.

Core Topics

Ansible fundamentals for DevOps

Learn the core Ansible concepts required to automate servers, infrastructure, deployments, and operational workflows.

01

Ansible Architecture

Understand how Ansible uses a control node to automate and manage multiple infrastructure systems and managed nodes.

Key Topics

  • • Control node
  • • Managed nodes
  • • Agentless automation
  • • Remote connections
02

Inventory

Learn how Ansible inventories define and organize managed hosts into groups for infrastructure automation.

Key Topics

  • • Static inventory
  • • Dynamic inventory
  • • Host groups
  • • Host variables
03

Playbooks

Learn how YAML-based playbooks define repeatable automation workflows, configurations, and deployment tasks.

Key Topics

  • • YAML syntax
  • • Plays
  • • Tasks
  • • Task execution
04

Modules

Understand Ansible modules and how they perform actions such as package installation, service management, file operations, and user management.

Key Topics

  • • Built-in modules
  • • Package modules
  • • Service modules
  • • File modules
05

Roles & Reusability

Learn how Ansible roles organize reusable automation content including tasks, variables, handlers, templates, and files.

Key Topics

  • • Ansible roles
  • • Reusable tasks
  • • Role structure
  • • Role dependencies
06

Variables & Automation

Learn how variables make Ansible automation reusable across different environments, hosts, and infrastructure configurations.

Key Topics

  • • Variables
  • • Group variables
  • • Host variables
  • • Templates

Command Line

Essential Ansible commands

Learn commonly used commands for inspecting Ansible, working with inventories, testing connectivity, executing playbooks, and managing automation content.

ansible --version

Display the installed Ansible version and configuration information.

ansible-inventory --list

Display inventory information and managed host details.

ansible all -m ping

Test connectivity to managed hosts using the Ansible ping module.

ansible-playbook playbook.yml

Execute an Ansible playbook against the configured inventory.

ansible-playbook --check playbook.yml

Run a playbook in check mode to preview potential changes.

ansible-playbook --syntax-check playbook.yml

Check playbook syntax before running automation tasks.

ansible-galaxy role init example_role

Create a basic directory structure for an Ansible role.

ansible-vault encrypt secrets.yml

Encrypt sensitive variables and files using Ansible Vault.

Automation Workflow

How Ansible automates infrastructure

Ansible uses an inventory to define the systems that automation targets. Playbooks define ordered plays and tasks, while modules perform specific actions on managed nodes.

A typical workflow defines infrastructure hosts, creates a playbook, validates the automation, and executes tasks across the selected systems. Ansible playbooks support repeatable configuration and multi-machine deployment workflows.

Server Configuration

Automate package installation, system configuration, users, services, files, and operating system settings.

Application Deployment

Automate repeatable application deployment workflows across development, testing, staging, and production environments.

Infrastructure Automation

Use automation playbooks to configure cloud infrastructure, servers, networking components, and supporting services.

Configuration Management

Maintain consistent system configurations across multiple servers and environments.

CI/CD Automation

Integrate Ansible playbooks with CI/CD pipelines to automate deployment and infrastructure workflows.

Network Automation

Automate configuration and management tasks for supported network devices and infrastructure platforms.
