Docker Networking & Swarm Mode Introduction

Download as PPTX, PDF

Phi Huynh

This document introduces Docker networking and Docker Swarm mode. It discusses the different types of Docker networks including bridge, null, and host networks. It also covers multi-host networking using overlay networks. For Docker Swarm mode, it describes the key features including self-healing, self-organizing, blue-print deployment, load balancing using a routing mesh, and not requiring additional components for service discovery or load balancing. The document aims to provide an overview of these topics and includes examples.

Introduction to Docker Networking & Docker Swarm Mode Phi Huynh
A bit history
 Docker Networking  Docker Swarm Mode (Docker v1.12)  Demo  Q&A Agenda
 Pre-defined Networks  Bridge (default) - Containers in local Docker0 bridge  Null - Containers has no network interface  Host - Containers use host’s network interface  Multi-Host Network (Docker v1.9)  Overlay network Docker Networking
Bridge Network Host Machine vnet-1 10.10.0.0/16 container 4 container 5 container 1 container 2 container 3
Bridge Network (Continued) Host Machine frontend-net 10.11.0.0/16 container 2 container 4 container 1 container 3 container 5 backend-net 10.12.0.0/16 container 6
Multi-host Networking - Overlay Network (from Docker 1.9) Host Machine 1 vnet-1 10.0.0.0/24 container 2 container 4 container 1 container 3 container 5 container 6 Host Machine 2 Reference source
