Course Description
Automation with Ansible and Ansible Tower
Automation with Ansible and Ansible Tower (DO410) teaches you how to develop standardized automation of the enterprise IT environment in order to improve operational efficiency. You will learn how to use Ansible for automation, configuration, provisioning, and management, as well as how to use Red Hat® Ansible Tower to centrally manage Ansible at an enterprise scale.
This Ansible Concepts course combines the content from Automation with Ansible (DO407) and Automation with Ansible II: Ansible Tower (DO409), and is based on Ansible 2.3 and Ansible Tower 3.3.
Through hands-on labs, you will learn to automate system administration tasks on managed hosts with Ansible, find out how to write Ansible playbooks to standardize task execution, and manage encryption for Ansible with Ansible Vault. This course will also teach you how to deploy and use Red Hat Ansible Tower to centrally manage existing Ansible projects, playbooks, and roles; perform basic maintenance and administration of the Ansible Tower installation; and configure users and teams and use them to control access to systems, projects, and other resources through role-based access controls. You will learn to use Ansible Tower's visual dashboard to launch, control, and monitor Ansible jobs; use the Ansible Tower application programming interface (API) to launch jobs from existing templates; automatically schedule Ansible jobs; and dynamically update host inventories.
The course material covered in this curriculum is now included within our newly released Red Hat System Administration III: Linux Automation with Ansible (RH294) and Advanced Automation: Ansible Best Practices (DO447) offerings. which cover how to use Red Hat Ansible Automation to automate across different functions.
