Managing OpenShift From Installation and Beyond

Slides from the hands on lab at Red Hat Summit 2017. Configuring distributed systems can be difficult. Fortunately, automation tools such as Ansible are available to help manage even the most complex environments. This lab allowed attendees to take the reigns of their own cluster and experience firsthand how Ansible can be used to install, configure, and maintain OpenShift to support mission-critical systems. Once the installation of Red Hat OpenShift is complete, attendees learned how to diagnose, troubleshoot, and resolve common platform issues. Managing the platform doesn't stop once the installation is complete. Ansible can be used to simplify ongoing maintenance and to make worry-free platform upgrades, all facilitated in an automated fashion. Finally, the use of centralized management systems will be introduced into the environment in order to demonstrate its importance and to provide a streamlined experience for both platform maintainers and users.
