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.

Configuring cgroup isolators

In this recipe, you will learn how to create a container with cgroups, that is, real resource isolation at the kernel level.

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...

cgroups isolators are enabled in the same manner as POSIX. We need to put a comma-separated list of isolators into the configuration file:

echo "cgroups/cpu,cgroups/mem,namespaces/pid" > /etc/mesos-slave/isolation

By default, Mesos uses soft CPU limits. This means a process will get at least the resources it was allocated but there is a huge chance that it will use more CPU time when doing more intensive operations. To change this behavior, create this file:

touch /etc/mesos-slave/cgroups_enable_cfs

How it works...

cgroup is a Linux mechanism for limiting and isolating processes. cgroup isolation creates a real container for our application. This means when it tries to allocate more memory...
