Course Overview
The Developing Containerized Apps on OpenShift course teaches modern software development best practices commonly used to develop and deploy enterprise applications on Openshift. In this course, you will learn the fundamentals of containerized software development and how to use them in your application.
On day one, participants learn how to use container technology in application design and building. Day two includes an introduction to the key Kubernetes principles and paradigms on OpenShift and how to use and deploy applications on the platform. On day three, participants learn the fundamentals of software automation and modern best practices for cloud-native software development.
Optional: On the final day, attendees learn about the most advanced development concepts and principles that ensure software is robust, reliable, and ready to run.
All described topics are conceptually elucidated before being tested in the lab. Labs use Openshift as the target platform.
