OpenShift 4 for Developers

• A general understanding of container concepts
• Software development experience

Audience

• Developers

OpenShift Container Platform (formerly OpenShift Enterprise) is a collection of software put together by Red Hat for deploying containers and Kubernetes in the enterprise. OpenShift Container Platform optimizes developer productivity with features such as, Red Hat CodeReady Workspaces, OpenShift Service Mesh, Kubernetes-based event-driven autoscaling, and Operator-enabled Red Hat OpenShift Container Storage.

In this instructor-led, live training (online or onsite), participants will learn how to create, update, and maintain applications using OpenShift Container Platform.

By the end of this training, participants will be able to:

• Undersand OCI (Open Containers Initiative) and its implications for using container enginees such as Docker in OpenShift.
• Understand the relationship between the different versions of OpenShift (OKP, OpenShift Container Platform, Red Hat OpenShift, etc.)
• Automate the software delivery pipeline.
• Apply DevOps principles to deliver software continuously.

Format of the Course

• Interactive lecture and discussion.
• Lots of exercises and practice.
• Hands-on implementation in a live-lab environment.
