11. Native Clustering System

12. Nodes Setup
• Docker 1.4.0 or later.
• TLS authentication
• Bind Docker on a network interface.
• -H 0.0.0.0:2375

13. Discovery
• hosted discovery service
swarm join --discovery token://<token> --addr=<node_ip:2375>
• static file describing the cluster
swarm manage --discovery file:///tmp/my_cluster -H=<swarm_ip:swarm_port>
• etcd
swarm manage --discovery etcd://<etcd_ip>/<path> -H=<swarm_ip:swarm_port>

14. Advanced Scheduling
• Filters
• Constraint
• Port
• Health
• Strategies
• bin packing
• random
