This DC/OS 101 tutorial will guide you through the steps necessary to get started using DC/OS.
Important: Mesosphere does not support this tutorial, associated scripts, or commands, which are provided without warranty of any kind. The purpose of this tutorial is to demonstrate capabilities, and may not be suited for use in a production environment. Before using a similar solution in your environment, you must adapt, validate, and test.
The tutorial is designed to provide users and applications developers an overview of the DC/OS basics. This tutorial discusses basic recipes for developing and orchestrating applications for a distributed landscape. To provide hands-on experience, you will develop and deploy multiple applications (including stateful, dockerized, and non-dockerized) on an actual cluster during each step of the tutorial. To provide even more rationale and background information the tutorial also includes optional deep dives into relevant topics.
The DC/OS 101 tutorial includes the following sessions:
Your app in the previous part of this tutorial used redis.marathon.l4lb.thisdcos.directory as the address for connecting to Redis, with port 6379. As Redis might be running on any agent in the cluster, and potentially on different ports, how does this address resolve to the actual running Redis instance?
Earlier in this tutorial you deployed an app that operates internally in your cluster, interfacing with other applications in the cluster as opposed to interacting externally. In this part you will deploy an app which provides a GUI to users. You will also deploy this app natively, without relying on Docker as a dependency and therefore reducing complexity.
Resource management and resource isolation between tasks are core functions of any operating system. In this section, you will learn how to monitor and understand your resource utilization, how resource limits are enforced, and how to debug resource management issues.
