Learning Docker Networking

Overview of this book

<p>Docker is a Linux container implementation that enables the creation of light weight portable development and production environments. These environments can be updated incrementally. Docker achieves this by leveraging containment principles like cgroups and Linux namespaces along with Overlay filesystem based portable images. Docker provides the networking primitives that allow administrators to specify how different containers network with each application and connect each of its components, then distribute them across a large number of servers and ensure coordination between them irrespective of the host or VM they are running in.</p> <p>This book will show you how to create, deploy, and manage a virtual network for connecting containers spanning single or multiple hosts.</p>

Mesosphere

Mesosphere is a software solution that provides ways of managing server infrastructures and basically expands upon the cluster-management capabilities of Apache Mesos. Mesosphere has also launched the DCOS (data center operating system), used to manage data centers by spanning all the machines and treating them as a single computer, providing a highly scalable and elastic way of deploying apps on top of it. DCOS can be installed on any public cloud or your own private data center, ranging from AWS, GCE, and Microsoft Azure to VMware. Marathon is the framework for Mesos and is designed to launch and run applications; it serves as a replacement for the init system. Marathon provides various features such as high availability, application health check, and service discovery, which help you run applications in Mesos clustered environments.

This session describes how to bring up a single-node Mesos cluster.
