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. The module ends with performing advanced cluster management tasks, such as configuring HA and performing cluster updates.

Module 4, “Sample Exam,” contains a sample exam, as well as some exam tips.
