1. Rapid Application Development!
in the Cloud and On-Premises!
with Docker !

2. Rapid Application Development!
§ Need for speed
§ Deliver new apps in days rather than months
§ Innovate via functional prototypes rather than UI sketches
§ Need for simplicity
§ Enable different types of developers including line of business
developers to build valuable apps

3. New Methodologies and new Technologies!
§ New methodologies
§ Agile
§ Design Thinking / Minimal Viable Product
§ New technologies
§ Open Source
§ StackOverflow
§ Tools, platforms, languages

4. Rapid Deployment ?!
§ Coding is often rapid, but deployment is (mostly) not
§ Issue: Different target platforms with different configurations
§ Expanded role of developers: Not only responsible to write
code but responsible for full life cycle up to the testing in
production environments
§ Old developer excuse “it works on my machine” doesn’t count any
longer

5. DevOps!
§ DevOps supports developers to automate testing and
deployments through delivery pipelines
§ But deployments can still be challenging
§ Different types of applications
§ Different target environments

6. Containers to the Rescue!

7. Containers vs. VMs!
§ Lighter weight than VMs (virtual machines)
graphics from docker.com

8. Enter Docker!
§ Standardizes the packaging of applications and container
runtimes
§ Write once run everywhere
§ Package once deploy everywhere

9. Introduction to Docker!
§ Enabling application development efficiency,
making deployment more efficient,
eliminating vendor ‘lock-in’ with true portability
§ Open
§ Software
§ Contribution
§ Design
§ Governance

10. Docker Terminology!
§ Image
§ Container
§ Registry
§ Engine
Cloud
On
Prem

11. Demo!
§ Simple Java web application on Liberty Profile
§ Create image locally
§ Run container locally

12. Sample Servlet!

13. Dockerfile!

14. Build Image!

15. Run Container!

16. Sample Application!

17. Same Sample on Tomcat!

18. Spring Boot Sample!

19. Docker Maven Plugin!
§ rhuss/docker-maven-plugin to build images and run
containers
§ mvn docker:build
§ mvn docker:start
§ mvn docker:stop
§ mvn
-Ddocker.removeAll
docker:remove

20. Registries to share Images!
§ Docker Hub
§ Public
§ Private
§ Docker Trusted Registry

21. Docker on IBM Bluemix!
§ Bluemix is IBM’s application platform in the cloud based on
Cloud Foundry
§ IBM extends and connects Docker containers to
production-ready enterprise environments
§ IBM hosted private registry
§ Run containers in local datacenters or in the cloud
§ External IP addresses
§ Integrated monitoring and logging
§ Security readiness guidance via Vulnerability Advisor

22. Demo!
§ Push image to Bluemix
§ Create container on Bluemix
§ Monitor container

23. Tag Image!

24. Push Image!

25. Push Image (cont.)!

26. Image Registry!

27. Run Container!

28. Running Container – Overview !

29. Sample Application!

30. Running Container – Instances !

31. Running Container – Monitoring !

32. Running Container – Logs !

33. Running Container – Advanced Logs !

34. Vulnerability Advisor!

35. Vulnerability Advisor (cont.)!

36. Automation via Delivery Pipelines!
§ To simplify the process to build images and run containers,
delivery pipelines can be used
§ Different deployment strategies can be used to deploy to
different target environments without downtimes

37. Demo!
§ Automate deployments via delivery pipelines

38. Java Code Modification!

39. Push Change!

40. Automatic Maven Build!

41. Automatic Docker Build!

42. Automatic Container Creation!

43. Completed Deployment!

44. Changed Application!

45. Bluemix Services for Docker Applications!
§ Bluemix allows not only the hosting of Docker applications
but also provides more than 100 services to build rapidly
applications without having to set up infrastructure
§ Services are provisioned when added to applications and
can be accessed via REST APIs (plus other language
bindings) with user specific credentials

46. Bluemix Services!
§ Databases
§ Services to build web apps
§ Cognitive services
§ Backends for mobile apps
§ Internet of Things
§ Analytics and Big Data
§ Access to on-prem services and data

47. Demo!
§ Leverage Bluemix services

48. Docker to Cloud Foundry Bridge!

49. Bind Services!

50. Bind Services (cont.)!

51. Bound Service with Credentials!

52. Sample Application accessing Credentials!

53. Take-Aways!
§ Docker containers allow the standardized packaging of
applications and easy deployments to different
environments
§ Docker is currently the de-facto container standard and is
evolving into the Open Container Initiative
§ IBM adds enterprise capabilities for Docker images and
containers
§ Try Docker in the cloud via the 30 days trial of Bluemix

54. Thank you!
