Red Hat OpenShift

Red Hat® OpenShift is a container application platform that brings Docker and Kubernetes to the enterprise. Regardless of your applications architecture, OpenShift lets you easily and quickly build, develop, and deploy in nearly any infrastructure, public or private. Whether it’s on-premise, in a public cloud, or hosted, you have an award-winning platform to get your next big idea to market ahead of your competition.

Course overview

Red Hat OpenShift Container Platform is a containerized application platform that allows enterprises to manage container deployments and scale their applications using Kubernetes. OpenShift Container Platform provides predefined application environments and builds upon Kubernetes to provide support for DevOps principles such as reduced time to market, infrastructure-as-code, continuous integration (CI), and continuous delivery (CD).

Outline for this course

○ Introduction to Red Hat OpenShift Container Platform
○ Install OpenShift Container Platform
○ Explore networking concepts
○ Execute commands
○ OpenShift Container Platform resources
○ Persistent storage
○ Manage application deployments
○ Metrics subsystem
○ Manage and monitor
○ Comprehensive review

Audience & Prerequisites

This course is designed for system administrators, architects, and developers who want to install and configure Red Hat OpenShift Container Platform.

Prerequisites for this course

○ Be certified as a Red Hat Certified System Administrator, or equivalent Red Hat Enterprise Linux system administration experience
○ Complete the Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) course or have equivalent experience with containers, Kubernetes, and OpenShift basics.

Course overview

Through hands-on labs, the student will implement user stories for an existing Java™ EE application and deploy the application to an OpenShift instance. The student will learn how to create, update, and maintain applications using Red Hat OpenShift Container Platform.

Outline for this course

○ Introduce and review the course.
○ Describe the developer's tools, agile practices, and deployment environment that will be utilized in this course.
○ Become familiar with the course application architecture, features, and project layout.
○ Describe the features and architecture of OpenShift Enterprise.
○ Define, build, and deploy an application on OpenShift Enterprise.
○ Establish continuous integration with Jenkins.
○ Control and maintain applications using the OpenShift Enterprise command line interface.
○ Create deployments that utilize clustering, load balancing, and customized node scheduling.
○ Use debugging and logs to troubleshoot problems with application performance or deployment issues.
○ Create custom source image containers, templates, and builders.
○ Practice the skills learned in this course.

Audience & Prerequisites

This course is designed for application developers (not necessarily Java EE developers) interested in creating OpenShift applications with automated unit/acceptance tests and deploying those applications using continuous integration (CI) to an OpenShift instance.

Prerequisites for this course

○ Java EE programming skills are helpful—we try to keep the programming tasks simple, like changing the color of an item on an HTML page—so general HTML skills common to many programming environments will suffice
○ Experience as a successful developer in one of the environments supported by Red Hat OpenShift Container Platform—either Python, Ruby, Java EE, Node.js
○ Have taken Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) or have equivalent experience

Course overview

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 of a robust OpenShift cluster in the remainder of the course.

Outline for this course

○ Design a highly available cluster
○ Prepare to install an HA cluster
○ Configure OpenShift to use custom certificates
○ Use the advanced installation method to build an HA OpenShift cluster.
○ Describe storage providers, configure a provider, create a storage class, and test the configuration.
○ Consolidate useful data for analysis by enabling the log aggregation feature.
○ Perform recurring maintenance activities on an OpenShift cluster.
○ Manage operating system and cluster resources for optimal performance.
○ Configure security providers and advanced security options.
○ Configure various advanced networking features and options.

Audience & Prerequisites

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

Red Hat recommends these prerequisites:

○ Become a Red Hat Certified System Administrator, or demonstrate equivalent experience
○ Attend Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) or demonstrate equivalent experience with containers, Kubernetes, and OpenShift
○ Attend Red Hat OpenShift Administration I (DO280) or demonstrate equivalent experience with OpenShift
○ Recommended, but not required: become a Red Hat Certified Specialist in OpenShift Administration (EX280)
