This playbook walks you through setting up Kubernetes the Alta3 way. This guide is a fully automated command to bring up a Kubernetes cluster using Ansible.
Kubernetes The Alta3 Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.
Kubernetes The Alta3 Way is used extensively within the student lab environments for Alat3's Kubernetes Bootcamp. In this course each student has access to their own high availability Kubernetes environment capable of demonstrating all of the โK8sโ features and components used in CKAD and CKA certifications (Certified Kubernetes Application Developer, Certified Kubernetes Administrator).
