About this Hands-on Lab

Ansible relies on an inventory for base functionality. While inventories can be very simple, they have been designed to be robust. This exercise walks through how to use some of the more advanced features available within an Ansible inventory. Upon completion of this exercise, students will have practical experience with Ansible inventory configuration.

Additional Resources

Your company decided that their backup software license was frivolous and unnecessary. Because of this, the license was not renewed. As a stopgap measure, your supervisor has created a simple script and an Ansible playbook to create an archive of select files, depending on pre-defined Ansible host groups. You will create the inventory file to complete the backup strategy.

Important notes:

  • For your convenience, Ansible has been installed on the control node.
  • The user ansible has already been created on all servers with appropriate shared keys for access to managed servers from the control node.
  • The ansible user has the same password as cloud_user.
  • /etc/hosts entries have been made on control1 for the managed servers.
