Introduction to Ansible
Ansible simplifies IT automation by providing a simple and powerful approach to configuration management, application deployment, and task automation.
Core Components
- Playbooks: YAML-based scripts to define tasks.
- Roles: Group related tasks for better organization.
- Modules: Reusable, standalone scripts to perform tasks.
Example Playbook
yaml code
name: Install Apache and start service
hosts: webservers
tasks: –
name: Install Apache
yum:
name: httpd
state: present
– name: Start Apache
service:
name: httpd
state: started
Benefits of Ansible
- Agentless: No need for agents on managed nodes.
- Easy to Learn: Simple, human-readable syntax.
Use Cases
- Configuration Management: Ensure consistency across servers.
- Orchestration: Coordinate services across multiple hosts.
