Apache Mesos Cookbook

By: David Blomquist, Tomasz Janiszewski

Overview of this book

Apache Mesos is open source cluster sharing and management software. Deploying and managing scalable applications in large-scale clustered environments can be difficult, but Apache Mesos makes it easier with efficient resource isolation and sharing across application frameworks. The goal of this book is to guide you through the practical implementation of the Mesos core along with a number of Mesos supported frameworks. You will begin by installing Mesos and then learn how to configure clusters and maintain them. You will also see how to deploy a cluster in a production environment with high availability using Zookeeper. Next, you will get to grips with using Mesos, Marathon, and Docker to build and deploy a PaaS. You will see how to schedule jobs with Chronos. We’ll demonstrate how to integrate Mesos with big data frameworks such as Spark, Hadoop, and Storm. Practical solutions backed with clear examples will also show you how to deploy elastic big data jobs. You will find out how to deploy a scalable continuous integration and delivery system on Mesos with Jenkins. Finally, you will configure and deploy a highly scalable distributed search engine with ElasticSearch. Throughout the course of this book, you will get to know tips and tricks along with best practices to follow when working with Mesos.

Enabling the Mesos containerizer

In this recipe, you will learn how to enable the Mesos containerizer. The Mesos containerizer (a.k.a. the unified containerizer) is the default way of running containers on Mesos. It can support multiple types of isolation, providing the ability to configure process isolation to match system requirements. Starting Mesos version 1.0, container images in Docker and AppC formats are supported.

Getting ready

You need to have Mesos up and running. See the recipes of Chapter 1, Getting Started with Apache Mesos to get more information.

How to do it...

The Mesos containerizer is enabled by default. To make it explicit, run the following command:

echo 'mesos' > /etc/mesos-slave/containerizers

How it works...

The Mesos agent reads the list of enabled containerizers and enables matching implementations. If you want to run a container that is not supported by a particular agent, the task won't start. The Mesos containerizer interacts with the native kernel's cgroups mechanism...
