Learn Apache Mesos

By: Manuj Aggarwal

Overview of this book

Apache Mesos is an open source cluster manager that provides efficient resource isolation and sharing across distributed applications or frameworks. This book will help you build a strong foundation of Mesos' capabilities along with practical examples to support the concepts explained throughout the book. Learn Apache Mesos dives straight into how Mesos works. You will be introduced to the distributed system and its challenges and then learn how you can use Mesos and its framework to solve data problems. You will also gain a full understanding of Mesos' internal mechanisms and get equipped to use Mesos and develop applications. Furthermore, this book lets you explore all the steps required to create highly available clusters and build your own Mesos frameworks. You will also cover application deployment and monitoring. By the end of this book, you will have learned how to use Mesos to make full use of machines and how to simplify data center maintenance.

Enabling and configuring authentication

Before anything else, we need to enable authentication, and for doing this, we need to define which authentication mechanism we want to use. Here, we will be using CRAM-MD5 because it is built into Mesos and is a popular authentication algorithm used in Simple Mail Transfer Protocol (SMTP) and Lightweight Directory Access Protocol (LDAP).

We will work on the following:

  • Master: This will enable the authentication of frameworks and agents.
  • Agent: We will create a file with the agent's secrets and this file will be used to authenticate the master.
  • Marathon: This accepts credentials in a different manner to Mesos. Instead of storing everything in one file, only secrets are stored in the file. We can pass this principal using the command-line flag.
