DO380 - Red Hat OpenShift Administration II: High Availability


Duration: 4.0 days

Design, build and test OpenShift HA cluster

RedHat OpenShift Administration II teaches you how to build robust clusters that provide high availability and the ability to run large numbers of applications. You will learn about OpenShift integration with datacenter infrastructures such as load balancers, identity management, monitoring, proxies, and storage. You will also develop more troubleshooting and Day 2 operations skills in this course.

This course is based on Red Hat® OpenShift Container Platform 3.6.

You will design an OpenShift HA cluster, then build and test it. You will use this cluster to examine more advanced topics in the administration and operation ofa robust OpenShift cluster in the remainder of the course.


In this course you will :

  • Understand container and OpenShiftarchitecture.
  • Create containerized services.
  • Manage containers and container images.
  • Create custom container images.
  • Deploy containerized applications on Red HatOpenShift.
  • Deploy multi-container applications.

You should be able to demonstrate these skills:

  • Design and install a highly available cluster.
  • Provision persistent storage using dynamic allocation.
  • Install the GlusterFS Container NativeStorage solution on an OpenShift cluster.
  • Enable log aggregation across the cluster.
  • Perform diagnostics on the cluster.
  • Back up and restore critical data for the cluster.
  • Manage OpenShift and operating system resources to keep the cluster running efficiently.
  • Configure the LDAP security provider.
  • Describe and install the Open vSwitchmultitenant software-defined networking provider.


This course is designed for Linux® system administrators who want to deploy andmanage a large-scale Red Hat® OpenShiftContainer Platform environment in their datacenters.
