Enabling the Mesos containerizer
In this recipe, you will learn how to enable the Mesos containerizer. The Mesos containerizer (a.k.a. the unified containerizer) is the default way of running containers on Mesos. It can support multiple types of isolation, providing the ability to configure process isolation to match system requirements. Starting Mesos version 1.0, container images in Docker and AppC formats are supported.
Getting ready
You need to have Mesos up and running. See the recipes of Chapter 1, Getting Started with Apache Mesos to get more information.
How to do it...
The Mesos containerizer is enabled by default. To make it explicit, run the following command:
echo 'mesos' > /etc/mesos-slave/containerizersHow it works...
The Mesos agent reads the list of enabled containerizers and enables matching implementations. If you want to run a container that is not supported by a particular agent, the task won't start. The Mesos containerizer interacts with the native kernel's cgroups mechanism...
