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.

Setting attributes for agents

In this recipe, we will set different attributes for our agents. Attributes are extremely useful when our cluster is not homogeneous and we want to distinguish agents from each other.

How to do it...

Let's assume our cluster contains agents with SSD and HDD drives. Disk resources will unify SSD and HDD, but from the user's perspective they are different and some tasks need to be run on SSD. We can label agents with the disk attributes hdd or ssd, depending on the disk type, hence allowing the user to decide which disk should be used for the job.

To create an attribute, we need to place the file in /etc/mesos-slave/attributes. The following command will create this directory:

mkdir -p /etc/mesos-slave/attributes

The filename will be the attribute label and the content will be a value. To create the disk:ssd attribute, simply create a file with the following contents:

echossd> /etc/mesos-slave/attributes/disk
