最新的 Docker 1.9.0 在 11 月份正式推出，此講題將介紹最新的 Network 的特性，介紹如何透過 Docker Machine 建置多台 Docker Engine，使用 Docker swarm 整合跨網路多主機叢集環境，最後在由 Docker Compose 來讓環境設置清楚易懂，達到三位一體夢幻的組合！

16. ‣ Port allow
‣ Docker Engine port (e.g TCP 2375)
‣ VXLAN: UDP 4789
‣ Serf: TCP + UDP 7946
‣ Key-value store ( e.g for Consul TCP 8500)
‣ Support Docker Network feature
‣ kernel 3.18+

17. Digital Ocean
‣ setup your token
‣ export DIGITALOCEAN_ACCESS_TOKEN=12345

18. Google Cloud Platform
‣ gcloud auth login https://cloud.google.com/sdk/
‣ create google-project
‣ export GOOGLE_PROJECT='project name'
‣ activate Compute Engine API
‣ setup firewall-rules
‣ gcloud compute firewall-rules update default-swarm --allow tcp:2376 tcp:2375
tcp:3376 tcp:8500 UDP:4789 TCP:7946 UDP:7946 --source-range 0.0.0.0/0
