DC/OS was declared end of life October 31, 2021 and the content is no longer maintained
Description
Lab Overview
DC/OS includes the powerful container orchestration tool called Marathon. Marathon supports multiple container types including Mesos and Docker. Marathon can schedule containers while satisfying a variety of constraints, load balance, perform health checks, and even comes with an intuitive graphical user interface (GUI).
In this Lab, you will deploy two Marathon applications using Mesos containers. You will also learn how to use Marathon to schedule Mesos containers on DC/OS from the DC/OS command-line interface (CLI) and the Marathon graphical user interface (GUI).
Lab Objectives
Upon completion of this Lab you will be able to:
- Write Marathon application definitions
- Deploy Marathon applications using Mesos containers using the DC/OS CLI
- Manage and monitor Marathon using the Marathon GUI
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
- Basic Amazon S3 concepts
- AWS services knowledge is useful in order to understand the architecture of the pre-created DC/OS cluster, but not required
Lab Environment
Before completing the Lab instructions, the environment will look as follows:
After completing the Lab instructions, the environment should look similar to:
