Overview

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions. Using the concepts of "labels" and "pods", it groups the containers which make up an application into logical units for easy management and discovery.

  • This course will provide students with an understanding of the foundational technologies behind Ansible, and show students how to use Ansible as a tool to manage computing infrastructure.

Reviews

This was effective way to provide a ton of information in a short time period.

I think the platform is very good and look forward to taking my next course in early October.

Good course. I appreciate the time the instructor put into teaching this class.

I liked the pace of the course. I like that I have more than instance to use the lab.

The exit certified aws course provided a good introduction to the tools available on aws.
