DO290 - Red Hat OpenShift Enterprise Development


Duration: 3 days

Developing and Deploying Applications on OpenShift (DO290) is part of a series of courses that focus on using OpenShift Container Platform to automate a portion of the software delivery pipeline. The course immerses the student in a DevOps environment through the use of agile software development methodology, test-driven development, continuous integration, and a standard operating environment through the use of Platform-as-a-Service (PaaS).

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.


As a result of attending this course, the student should be able to take advantage of the platform in a popular DevOps environment. This course is part of a series of DevOps courses centered on the use of OpenShift to enable continuous delivery—a key goal in the DevOps philosophy. Red Hat is committed in being a leader in providing prescriptive approaches to DevOps using Red Hat and other open source technologies.

Students should be able to demonstrate the following skills:

  • Deploy applications in Docker using images
  • Describe the architecture of Red Hat OpenShift Container Platform
  • Control and maintain applications using the OpenShift command-line interface
  • Define, build, and deploy an application on Red Hat OpenShift Container Platform
  • Establish continuous integration of an application from source code to deployment using Jenkins
  • Create deployments that utilize clustering, load balancing, and customized node scheduling
  • Troubleshoot problems involving application performance or deployment with debugging tools and log files
  • Create custom source-to-image (s2i) builder images and templates
  • Deploy a mutli-pod application to Red Hat OpenShift Container Platform using Jenkins for continuous integration
  • Install and update software packages
  • Access Linux file systems
  • Manage Linux networking


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.

Red Hat recommends these prerequisites:

  • 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.


This course is not associated with any Certification.
