Description

Lab Overview

By working with Marathon pods in DC/OS you can share resources among a group of applications on a single agent and manage them as a single unit. This is often used for running a logging or analytics application alongside a primary application. Legacy applications may also fit into a pod without having to update any code. For example, if services in a legacy application communicate over the loopback network interface. In this Lab, you will deploy a couple of pods to illustrate the capabilities and limitations of working with Marathon pods in DC/OS.

Lab Objectives

Upon completion of this Lab you will be able to:

  • Write Marathon pod definitions
  • Manage Marathon pods from the DC/OS GUI and CLI
  • Use volumes, health checks, and endpoints with pods

Lab Prerequisites

You should be familiar with:

  • Basic DC/OS concepts including master nodes, agents, services, tasks, and Marathon
  • Working at the command-line in Linux
  • AWS services knowledge is useful in order to understand the architecture of the pre-created DC/OS cluster, but not required
