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.

Launching a Docker container

In this recipe, you will learn how to launch a Docker container using the Marathon API. Marathon, as with most Mesos frameworks, is able to run Docker containers. This is extremely useful in a private PaaS because developers are able to ship their machines into production with one simple click without worrying about server configuration or asking admins for help.

Getting ready

Before you start, ensure Marathon is up and running and Mesos has enabled Docker support. You can find more information in Chapter 5, Managing Containers.

How to do it...

The operation is similar to running a command. The main difference is that we need to pass the Docker image description and its configuration such as ports, variables, and optional Docker parameters. Remember to enable Docker support on Mesos agents before proceeding.
