3. Docker   •  IntroducCon   •  Popularity   •  History   •  Ecosystem  
4. Docker  
5. Docker   •  Technical   •  Containers   •  Micro  Services   •  Dockerfiles   –  ConfiguraCon   –  Volumes   –  Composable  
6. Docker   •  Cloud  Usage   •  OpenStack   •  Manual  Process   –  CredenCals  and  Keys   –  OperaCng  System  and  Hardware   –  Download  and  InstallaCon   –  ConfiguraCon   –  Dockerfile  per  Service

10. DemonstraCon   Deploying  a  Docker  Cloud  
11. Clocker   •  Demand  Side   –  Create  a  New  Container   –  Resize  Cluster  of  EnCCes   –  AutoScaler  Policy  ATached  to  Cluster   •  Supply  Side   –  Placement  Strategies  for  Containers   –  Depth  or  Breadth  First   –  Affinity  Rules   –  Resource  AllocaCon  (CPU  Shares,  Load,  Memory,  …)  
12. Clocker   •  ApplicaCon  Deployment   –  CAMP  Blueprint  in  YAML   –  Java  Classes   –  Mostly  Unchanged   •  Docker  Specific  ConfiguraCon   –  Affinity  Rules  or  Placement  Strategy   –  Dockerfile  or  Image  ID   –  CPU  or  Memory  Shares   –  Docker  Volumes
