Introduction to Kubernetes

Categories: Kubernetes
Course Length: 2 Days

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

This introductory course is to level up operations and developers on how to use and maintain Kubernetes. This course starts with an introduction to Docker, then we proceed to an introduction to Kubernetes where we cover the history and what problems Kubernetes tries to solve. We then cover installation and necessary CLI utilities. We follow up describing the architecture of a Kubernetes cluster. Then we dig into how to do the common real-world operations like installing your app, scaling your app, viewing a dashboard, creating services and ingresses, deploying volumes, and administering your cluster.

Prerequisites: Comfort with the Command-Line, Comfort with an Editor, Basic knowledge of networking and internet communication.
