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.

Agent authentication

In this recipe, you will learn how to authenticate agents to prevent alien agents and frameworks joining the cluster.

Getting ready

Before we start configuring authentication, we need to identify the principals of our cluster and generate secrets for them. In the following example, we assume we have two principal marathon (framework) and agent (all agents).

How to do it...

To enable authentication, we need to define which authentication mechanism we want to use. In this example, we will use CRAM-MD5, which is built into Mesos and is, in fact, quite a popular authentication algorithm used in SMTP and LDAP.


Enable authentication of frameworks and agents by setting:

echo true > /etc/mesos-master/authenticate_frameworksecho true > /etc/mesos-master/authenticate_agents

Choose CRAM-MD5 as an authenticator:

echo crammd5 > /etc/mesos-master/authenticators

Create a file with the principals' secrets. Secrets provided by the principal will be checked against this file during...
