Red Hat System Administration III: Linux Automation (RH294) for Linux system administrators and developers who need to automate provisioning, configuration, application deployment, and orchestration.
Students will learn how to install and configure Ansible on a management workstation and prepare managed hosts for automation. Students will write Ansible Playbooks to automate tasks and run them to ensure servers are correctly deployed and configured. Examples of approaches to automate common Linux system administration tasks will be explored.
Audience
Linux system administrators, DevOps engineers, infrastructure automation engineers, and systems design engineers responsible for automation of configuration management, consistent and repeatable application deployment, provisioning and deployment of development, testing, and production servers, and integration with DevOps CI/CD workflows.
