Kubernetes - OpenShift:
Understanding the Differences (Extended)

Course Description

If you are already familiar with the basics of containerization and the usage of Kubernetes, it is time to add OpenShift to your arsenal! This comprehensive OpenShift training equips you with the skills to confidently deploy, manage, and leverage the power of the OpenShift container platform. The curriculum delves into the core concepts of OpenShift, empowering you to gain a deep understanding of the platform's architecture for running microservices reliably.

Throughout the course, you'll gain hands-on experience with essential OpenShift functionalities. Learn to install and configure OpenShift Local (the single machine version of OpenShift, ideal for a learning environment), explore the Web Console and oc CLI for efficient platform management, and deploy applications using Docker images or source code. We'll cover advanced topics like scaling applications automatically, implementing zero-downtime deployments, and utilizing OpenShift operators for streamlined automation.

Explore the principles of CI/CD (Continuous Integration/Continuous Delivery) and its seamless integration with OpenShift, as well as learn to install OpenShift in a disconnected environment. By the end of the course, you'll be empowered to establish efficient and reliable deployment pipelines, accelerating your development process.

Course Objectives

Upon completion, you will be able to confidently:

• Understand and articulate the key architectural and feature differences between OpenShift and vanilla Kubernetes.
• Deploy and manage your own applications using various methods, including Docker images and source-to-image (S2I) builds.
• Implement critical security measures using Security Context Constraints (SCCs) and manage cluster resources effectively with quotas.
• Set up and troubleshoot logging and monitoring stacks for applications and cluster health.
• Execute the advanced process of installing and configuring a disconnected OpenShift cluster, a crucial skill for high-security environments.
