Native Docker Clustering with Swarm

Overview of this book

Docker Swarm serves as one of the crucial components of the Docker ecosystem and offers a native solution for you to orchestrate containers. It’s turning out to be one of the preferred choices for Docker clustering thanks to its recent improvements. This book covers Swarm, Swarm Mode, and SwarmKit. It gives you a guided tour on how Swarm works and how to work with Swarm. It describes how to set up local test installations and then moves to huge distributed infrastructures. You will be shown how Swarm works internally, what’s new in Swarmkit, how to automate big Swarm deployments, and how to configure and operate a Swarm cluster on the public and private cloud. This book will teach you how to meet the challenge of deploying massive production-ready applications and a huge number of containers on Swarm. You'll also cover advanced topics that include volumes, scheduling, a Libnetwork deep dive, security, and platform scalability.

Preface

Encryption and routing mesh


The model at the heart of Libnetwork is CNM, as previously mentioned. In Swarm mode, libnetwork is built in a cluster-aware mode and supports multi-host networking without external key value stores. The overlay network fits naturally in this model. And both Data plane and Control plane encryption has been introduced. With encrypted Control Plane, routing information on VXLAN, for example, for which container has which MAC address and which IP address, is automatically secured. Also, with Routing Mesh, CNM provides a decentralized mechanism allowing you to access services from any IP of the cluster. When a request comes from the outsideand hits any node of the cluster, the traffic will be routed to a working container.
