Docker summit 2015: 以 Docker Swarm 打造多主機叢集環境
The document outlines the configuration and management of Docker Swarm and networking, including linking containers, setting up multi-host networking, and orchestrating Docker services across cloud and local environments. It provides specific Docker commands, container setups, and examples for services like MySQL and web applications, along with links to resources and GitHub repositories. Additionally, it covers network creation, firewall rules setup for Digital Ocean and Google Cloud, and emphasizes high availability in Docker Swarm.
