DO720 Container Adoption Boot Camp for Developers

Developers interested in adopting container technology and developing microservices.

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.
• Use the Config specification to inject data into a microservice.
• Implement fault tolerance in a microservice using OpenShift Service Mesh.
• Secure an OpenShift Service Mesh.

• Become a Red Hat Certified System Administrator (RHCSA), or demonstrate equivalent experience
• Red Hat Application Development I: Programming in Java EE (AD183), or experience with Java EE development
