ABOUT THE COURSE
Developing and Deploying Applications on OpenShift (DO290)
Learn to create, update, and maintain applications using OpenShift Container Platform
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.
Course content summary
