RHEL 8 Training Overview
This Red Hat Enterprise Linux 8 (RHEL 8) System Administration III training course presents the system management and configuration tool Ansible, including methods, techniques, capabilities, and implementation. Participants learn how to configure an Ansible control machine and understand the impact on the Linux system. Attendees learn how to write and apply playbook definitions, a key part of Ansible, allowing the synchronization of Linux, Unix, and Windows systems. This course is comparable to Red Hat course 129.
Note: This class can be customized to be 3, 4, or 5 days depending on what areas are needed for your team.
