Apache Mesos Cookbook

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.

Using the Docker containerizer

In this recipe, you will learn how to enable and run Docker images with a Docker containerizer. What this means is instead of using the Mesos implementation of standard Docker, we will use the Docker daemon to run images.

These days, Docker is the standard for containerization. Mesos supports two ways of launching Docker images. The first implemented was Docker containerizer, which is just a wrapper for the Docker daemon. Mesos does not launch containers itself. Instead, it asks the Docker daemon to do it. When a container is launched, Mesos monitors its state and bypasses framework commands (for example, kill) to the Docker daemon.

There is a second way of running Docker images, introduced in Mesos 1.0. It uses the Mesos containerizer to launch Docker images. Using this approach, no Docker installation is required and Mesos performs all the operations itself.

Getting ready

Install Docker on all agents:

sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers...
