Managing Clusters and Containers with Kubernetes
-
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.
