Fundamentals of Containers, Kubernetes and OpenShift

Ricardo da Costa

Fundamentals of Red Hat OpenShift for Developers is an introduction to deploying applications in the OpenShift ecosystem. This course provides the foundational knowledge to build, run, and manage containerized applications using OpenShift resources. We start by defining Kubernetes and OpenShift terminology and concepts as well as the advantages of containerized applications. Next, we will demonstrate various application deployment techniques using both the web console and the command line. After learning how to expose applications to external access, we will cover how to effectively manage the application lifecycle using various deployment strategies and dynamic configuration management. Lastly we will cover basic strategies for monitoring application health and troubleshooting deployments. Our goal is to provide you with a solid foundation in OpenShift, ensuring you can leverage its full potential in developing robust, scalable, and reliable applications.
