Managing Clusters and containers with Kubernetes Training

Course #:WA2507

Managing Clusters and containers with Kubernetes Training (Coming Soon)

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.

Objectives

In this training, attendees will learn how to:

  • Understand the architecture of Kubernetes and use basic terminology
  • Design and Manage Kubernetes Clusters

Prerequisites

Attendees should be comfortable using command shell commands in a Linux or Unix environment.

Duration

3 days
