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.

Upgrading Mesos

In this recipe, you will learn how to upgrade your Mesos cluster.

How to do it...

Mesos release cadence is at least one release per quarter. Minor releases are backward compatible, although there could be some small incompatibilities or the dropping of deprecated methods. The recommended method of upgrading is to apply all intermediate versions. For example, to upgrade from 0.27.2 to 1.0.0, we should apply 0.28.0, 0.28.1, 0.28.2, and finally 1.0.0.

If the agent's configuration changes, clearing the metadata directory is required. You can do this with the following code:

rm -rv {MESOS_DIR}/metadata

Here, {MESOS_DIR} should be replaced with the configured Mesos directory.

Rolling upgrades is the preferred method of upgrading clusters, starting with masters and then agents.

To minimize the impact on running tasks, if an agent's configuration changes and it becomes inaccessible, then it should be switched to maintenance mode.
