Course Overview

Master the essentials of Kubernetes in this intensive 2-day crash course. This is a condensed version of our comprehensive 5-day class, focusing strictly on the core fundamentals of container orchestration, deployments, and services. It is the perfect fit for developers and DevOps professionals who need to get up to speed quickly but don't have the time or budget for the full 5-day training. You will still gain practical, hands-on experience with real-world scenarios, ideal for those working with vanilla Kubernetes, OpenShift, AKS, GKE, or other distributions.

Course Prerequisites

Students are expected to have basic knowledge of a Container runtime such as Podman or Docker. At a bare minimum students should be familiar with Images, Containers, Volumes, Repositories. We advise students to follow our DOCKER-4K8S (or the full DOCKER-CORE)

Outline

If you are looking for our full 5-day class, check out K8S-CORE. In case you are looking for a course to set up and manage a cluster, we also offer the admin course K8S-ADMIN. Those longer courses also prepare you for the official exams (CKAD and CKA respectively).
