RH294: Red Hat System Administration III: Linux Automation with Ansible

Learn how to automate Linux system administration tasks with Ansible! Red Hat System Administration III: Linux Automation with Ansible (RH294) teaches the skills needed to manage large numbers of systems and applications efficiently and consistently. You will learn the techniques needed to use Ansible to automate provisioning, configuration, application deployment, and orchestration.

This course is based on Red Hat® Enterprise Linux 9 and Red Hat Ansible Automation Platform 2.2.

Course content summary

• Install Red Hat Ansible Automation Platform on control nodes
• Create and update inventories of managed hosts and manage connections to them
• Automate administration tasks with Ansible Playbooks and ad hoc commands
• Write effective playbooks at scale
• Protect sensitive data used by Ansible Automation Platform with Ansible Vault
• Reuse code and simplify playbook development with Ansible Roles and Ansible Content Collections.

Course outcome
