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.

Launching an application

In this recipe, you will learn how to launch an application using the Marathon API. We will create our first application using the API and then write a simple Python script to obtain information about where it has been deployed. Marathon provides a REST API that allows us to easily wire it with CI/CD systems using a simple script.

Getting ready

Before you start, ensure Marathon is up and running.

How to do it...

When you log in to Marathon, you can manually click to deploy an application. The Marathon UI is great, but limited to performing only basic deployments. In the following examples, you will see how to interact with Marathon using its API. This will enable you to plug in Marathon as a final step of your CI/CD solution.

There are two types of applications: native and Docker.

  1. The first example will show how to deploy a simple web server:
cat <<EOF > caddy.json
  "id": "web/server",
  "cmd": "echo \"It's working!\" > index.html &&
