Ansible Practical Tutorial for Beginners | Ansible Ad-hoc Commands | DevOps | SRE

This tutorial provides a practical, step-by-step demonstration of Ansible, building upon prior theoretical concepts. The content focuses specifically on setting up and executing Ansible ad-hoc commands within a DevOps or SRE context. The demonstration covers the initialization process, including creating a Control Node and Managed Nodes using AWS EC2 instances, establishing SSH connectivity, and installing Ansible on the control machine. Furthermore, it details the creation of an inventory file necessary for managing remote servers.

Users are guided through executing fundamental Ansible ad-hoc commands. These practical examples include running commands such as 'ping', 'uptime', and 'df -h' against the managed remote servers to verify connectivity and gather basic system information. The objective is to provide beginners with a clear understanding of how Ansible facilitates immediate server management actions without requiring complex YAML structures, contrasting with the subsequent topic of Ansible Playbooks.
