Course description

Supporting the adoption of container technology through the development of container-native applications

The Container Adoption Boot Camp for Developers (DO720) immerses you in intensive, hands-on development of container-native applications deployed on Red Hat's implementation of Kubernetes, Red Hat® OpenShift® Container Platform. As part of enrollment, you will receive one year of Red Hat Learning Subscription Standard, which gives you unlimited access to all of our courses online, plus up to five certification exams and two retakes. This boot camp is for those seeking to make a quantum leap in their journey toward digital transformation. Making this shift involves developing software in tight iterations so that business value can be realized sooner. In order to accomplish this goal, this offering can facilitate the adoption of container-native applications, including microservices.

This collection of courses is based on Red Hat OpenShift Container Platform 4.6.

Impact on the organization

This boot camp is intended to provide developers who have basic to intermediate knowledge of containers with the foundational and advanced skills needed to develop, deploy, and troubleshoot microservices applications with Red Hat OpenShift Container Platform. Red Hat OpenShift Container Platform enables rapid application development and deployment, as well as portability of an application across environments. The platform also offers simplified application scaling, administration, and maintenance of adaptive or cloud-native applications.

Impact on the individual

As a result of attending this course, you should be able to install, configure, and manage a Red Hat OpenShift Container Platform cluster and deploy applications on it.

You should be able to demonstrate these skills:

• Create and manage custom container images.
• Deploy applications to OpenShift Container Platform.
• Develop microservices using Quarkus.
• Design container images to containerize applications.
• Customize application builds and implement post-commit build hooks.
• Create a multi-container application template.
• Implement health checks to improve system reliability.
• Implement unit and integration tests for microservices.
