9+ Hours of Video Instruction

Certified Kubernetes Administrator (CKA) Complete Video Course provides more than 9 hours of video instruction for IT professionals—including IT Administrators, DevOps Engineers, Software Developers, IT Architects, and Hybrid Cloud Administrators—preparing to take the CKA exam, which requires an in-depth knowledge of how to develop, create, manage, store, and troubleshoot Kubernetes applications.

The course includes labs, demonstrations, and lightboard explanations by Sander van Vugt, who has presented on dozens of Linux and Kubernetes courses. He introduces containers and Kubernetes, and moves through the process of creation, managing, and storing applications. He provides labs on setting up and managing clusters, and you'll also learn how to troubleshoot Kubernetes applications and cluster nodes. Sander shows how to manage deployments, services, ingress, and setting up storage, and walks through key troubleshooting scenarios. He ends the course with a sample exam for the user to practice before taking the real thing.

Topics include:

Module 1: Getting Started
Module 2: Managing Pods and Deployments
Module 3: Managing Kubernetes Clusters
Module 4: Sample Exams

Lesson Descriptions

Module 1, "Getting Started," provides a quick overview of Kubernetes, how to use it, and then how to set up an on premise Kubernetes cluster.

Module 2, "Managing Pods and Deployments," digs into the essentials of working with Kubernetes, including how to work with the API and related utilities to configure Kubernetes. Managing pods, deployments, and storage are all covered in Module 2, as well as how to expose applications that are offered by Pods by using service objects.

Module 3, "Managing Kubernetes Clusters," covers how to manage Kubernetes clusters. It starts with a short lesson about API specifications and creating custom API objects. Then, it discusses scheduling and how this can be used to manage which nodes will service Pods. Security settings and working with all the different aspects of security in the cluster are covered. Networking and how the CNI and network plugins are used to implement the cluster is also covered. Managing nodes and clusters, as well as troubleshooting in a Kubernetes environment, are discussed in this large Module.

Module 4, "Sample Exams," contains a sample exam, as well as some exam tips.
